Three heater units each taking 1,500 watts are connected delta to a 120 Volt three phase line. What is the resistance of each unit in ohms? A. 9.6 B. 5.4 C. 8.6 D. 7.5

Answers

The resistance of each heater unit is approximately 8.6 ohms.

When three heater units are connected delta to a three-phase line, the power (P) consumed by each unit can be calculated using the formula:

P = (V^2) / (R * √3),

where P is the power, V is the voltage, R is the resistance, and √3 is the square root of 3.

In this case, V = 120 Volts and P = 1,500 Watts.

We can rearrange the formula to solve for resistance:

R = (V^2) / (P * √3).

Substituting the given values, we have:

R = (120^2) / (1,500 * √3)

R = 14,400 / (1,500 * 1.732)

R ≈ 14,400 / 2,598

R ≈ 5.54 ohms

Therefore, the resistance of each heater unit is approximately 5.54 ohms.

How is this answer derived?

Answers

Answer:

The answer to your question depends on the context and the system architecture you're dealing with. However, it seems that you're dealing with a 64-bit architecture where virtual addresses are translated to physical addresses using a page table structure. In this context, a PTE (Page Table Entry) contains hardware-readable data that the system uses to translate virtual addresses into physical addresses.

To answer your specific question, when you dereference a virtual address, you get a pointer to the associated PTE. In your case, you're dereferencing the virtual address 0x123456018, which is the virtual address of the second-level page table entry for the address you're interested in. By dereferencing this address, you obtain the contents of the second-level page table entry (PTE) which is 0x0000000000774101.

Without more context, it's difficult to say more about what this value represents, but it's likely that this PTE contains information such as the physical address of the page or page table that contains the actual requested data.

Compare two of the widely used compute resources in software development: AWS Lambda vs EC2. Analyze infrastructure management, performance and cost comparison.
Discuss the evolution of AWS computing resources from EC2 to AWS Lambda and identify potential use cases that will favor one option over the other

Answers

AWS Lambda and EC2 are two widely used compute resources in software development. AWS Lambda is a serverless computing service that allows developers to run code without provisioning or managing servers, while EC2 (Elastic Compute Cloud) provides virtual servers in the cloud.

AWS Lambda and EC2 are two popular compute resources provided by Amazon Web Services (AWS). AWS Lambda is a serverless computing service that allows developers to run code without managing servers. It follows an event-driven architecture and automatically scales based on the incoming workload. On the other hand, EC2 is a service that provides virtual servers in the cloud. It offers more control and flexibility as developers have direct access to the underlying infrastructure.

In terms of infrastructure management, Lambda abstracts away server management, allowing developers to focus solely on writing code. EC2, on the other hand, requires manual provisioning and management of virtual servers.

Performance-wise, EC2 provides more control over resources, allowing developers to optimize the performance of their applications. Lambda, on the other hand, automatically scales and allocates resources based on the incoming workload, offering efficient resource utilization.

When it comes to cost, Lambda can be more cost-effective for short-lived and infrequent workloads since you only pay for the actual execution time of your code. EC2, on the other hand, involves paying for the provisioned servers, regardless of their usage.

The evolution of AWS computing resources from EC2 to Lambda signifies a shift towards serverless computing, where developers can focus more on writing code and less on infrastructure management. Lambda offers faster development, reduced operational overhead, and efficient resource allocation.

Use cases that favor Lambda include event-driven applications, real-time file processing, and microservices, where the workload can be unpredictable and sporadic. EC2 is more suitable for applications that require full control over the underlying infrastructure, high performance, and scalability, such as large-scale web applications and databases.

Ultimately, the choice between Lambda and EC2 depends on the specific requirements of the application, including factors such as workload patterns, scalability needs, control over infrastructure, and cost considerations.

A balanced Y-Y three-wire, positive-sequence system has Van = 200∠0 V rms and Zp = 3 + j4 ohms. The lines each have a resistance of 1 ohm. Find the line current IL , the power delivered to the load, and the power dissipated in the lines.

Answers

Line current (IL): 69.28∠-53.13 A rms.

Power delivered to the load: 5,555.56 W (or 5.56 kW)

Power dissipated in the lines: 1,111.11 W (or 1.11 kW)

Now let's explain and calculate how we arrived at these values:

In a balanced Y-Y three-wire system, the line voltage (VL) is related to the phase voltage (Van) by the expression VL = √3 * Van. Therefore, VL = √3 * 200∠0 V rms = 346.41∠0 V rms.

The line current (IL) can be calculated using Ohm's law as IL = VL / Zp, where Zp is the per-phase impedance. In this case, Zp = 3 + j4 ohms. Substituting the values, we get IL = 346.41∠0 V rms / (3 + j4 ohms). To simplify the calculation, we can convert the impedance to polar form: Zp = 5∠53.13 degrees ohms. Now, dividing the voltage by the impedance, we have IL = 346.41∠0 V rms / 5∠53.13 degrees ohms. Simplifying further, IL = 69.28∠-53.13 A rms.

The power delivered to the load can be calculated as Pload = √3 * VL * IL * cos(θVL - θIL), where θVL and θIL are the phase angles of VL and IL, respectively. In this case, Pload = √3 * 346.41 V rms * 69.28 A rms * cos(0 degrees - (-53.13 degrees)). Evaluating this expression, we find Pload = 5,555.56 W (or 5.56 kW).

The power dissipated in the lines can be calculated as Pline = 3 * IL^2 * R, where R is the resistance of each line. In this case, R = 1 ohm. Substituting the values, we get Pline = 3 * (69.28 A rms)^2 * 1 ohm. Evaluating this expression, we find Pline = 1,111.11 W (or 1.11 kW).

In conclusion, for the given balanced Y-Y three-wire system with Van = 200∠0 V rms and Zp = 3 + j4 ohms, the line current (IL) is 33.33∠-36.87 A rms, the power delivered to the load is 5,555.56 W (or 5.56 kW), and the power dissipated in the lines is 1,111.11 W (or 1.11 kW).

The Laplace transform of f(t) is: 4 1 s+2 L{ƒ(1)} = =+ + S (s+2) +1 (s+2)² +1 Calculate f(x) = ?

Answers

The inverse Laplace transform of the given expression is:

f(t) = e^(-2t) * cos(t)

The Laplace transform of f(t) is given as:

L{f(t)} = 4 / [(s + 2)(s^2 + 4s + 5)]

To calculate the inverse Laplace transform, we can decompose the denominator into partial fractions:

(s^2 + 4s + 5) = (s + 2)^2 + 1

Therefore, the partial fraction decomposition becomes:

4 / [(s + 2)(s^2 + 4s + 5)] = A / (s + 2) + (Bs + C) / [(s + 2)^2 + 1]

Multiplying both sides by the denominator (s + 2)(s^2 + 4s + 5), we get:

4 = A[(s + 2)^2 + 1] + (Bs + C)(s + 2)

Expanding and simplifying the equation, we have:

4 = As^2 + 4As + 2A + Bs^2 + 2Bs + Cs + 2C

Matching the coefficients of s^2, s, and the constants on both sides, we get the following equations:

A + B = 0    (coefficients of s^2)

4A + 2B + C = 0    (coefficients of s)

2A + 2C = 4    (constants)

Solving these equations, we find A = 2, B = -2, and C = -2.

Therefore, the partial fraction decomposition becomes:

4 / [(s + 2)(s^2 + 4s + 5)] = 2 / (s + 2) - 2s - 2 / [(s + 2)^2 + 1]

Now, we can use the inverse Laplace transform tables to find the inverse Laplace transform of each term.

The inverse Laplace transform of 2 / (s + 2) is 2e^(-2t).

The inverse Laplace transform of -2s is -2u'(t), where u'(t) represents the unit step function derivative.

The inverse Laplace transform of -2 / [(s + 2)^2 + 1] is -2e^(-2t)sin(t).

Therefore, the inverse Laplace transform of L{f(t)} is:

f(t) = 2e^(-2t) - 2u'(t) - 2e^(-2t)sin(t)

The inverse Laplace transform of the given expression L{f(t)} is f(t) = 2e^(-2t) - 2u'(t) - 2e^(-2t)sin(t).

Answers

In the `main` function, we ask the user to enter a number and then call the `is_palindrome` function to check if the number is a palindrome. The program then prints the appropriate message based on the result.

Here's a Python program that checks if a number is a palindrome or not using a recursive function:

```python

def is_palindrome(number):

   # Base case: Single digit numbers are palindromes

   if number // 10 == 0:

       return True

   # Recursive case: Check the first and last digits

   elif number % 10 == number // (10 ** (len(str(number)) - 1)):

       # Remove the first and last digits and call the function recursively

       return is_palindrome((number % (10 ** (len(str(number)) - 1))) // 10)

   else:

       return False

def main():

   number = int(input("Enter a number: "))

   if is_palindrome(number):

       print(f"{number} is a palindrome!")

   else:

       print(f"{number} is not a palindrome!")

# Run the main function

main()

```

In this program, we define the `is_palindrome` function which uses recursion to check if a number is a palindrome. The function compares the first and last digits of the number and removes them for the next recursive call. The base case is when the number has a single digit, which is considered a palindrome.

For example, if the user enters `16461`, the program will output: `16461 is a palindrome!`. If the user enters `12345`, the program will output: `12345 is not a palindrome!`.

Line Parameters are z = 0.028 + j0.32 Ω/km and y = j3.5 x 10-6 S/km. The Line data completely transposed 275 kV, 150 km line has 2 ACSR conductors per bundle.

The voltage at the receiving end of the line = 95% of the rated voltage = 261.25 kV.

Full load at the receiving end of the line = 550 MW at 0.99 pf leading. The medium line model is used for the calculation

a) i)  ABCD parameters of the nominal + circuit: Impedance Z = 0.028 + j0.32 Ω/km

Admittance Y = j3.5 x 10-6 S/km= 0.035 x 10^-3 S/km

For the 150 km long transmission line, ZL = Z/2 * l = (0.028 + j0.32) * 150 = 4.2 + j48 ΩY L = Y/2 * l = (0.035 x 10^-3) * 150 = 5.25 x 10^-3 S.

This implies Primary series impedance per phase/ unit length,

z = (ZL + Zc)/2l = (4.2 + j48)/2 * 150 = 0.014 + j0.16 Ω/km.

Primary shunt admittance per phase/unit length,

y = (YL + Yc)/2l = (5.25 x 10^-3)/2 * 150 = 0.3937 x 10^-5 S/km.

The primary line constants are converted into ABCD parameters as follows:

z = 0.014 + j0.16 Ω/km, y = 0.3937 x 10^-5 S/km

β = (z * y)^0.5 = 0.04868 γ = (y * z)^0.5 = 0.004172 A = cosh(β * l) = 3.5696 B = Zc * sinh(β * l) = 149.9818C = Yc * sinh(γ * l) = 0.665 D = cosh(γ * l) = 1.0003

Thus, ABCD parameters of the nominal + circuit = [(3.5696 + j149.9818), (0.665 + j0.0147); (0.665 + j0.0147), (3.5696 - j149.9818)]

(ii) Receiving end voltage, VR and current, IR: The receiving end power = 550 MW at 0.99 pf leading Rated voltage = 275 kV

The sending end voltage Vs can be calculated using the following formula: Vs = VR + (IR) * (z + jy) + (VR) * (y / 2)Vs = 261.25 kV + (IR) * (0.014 + j0.16) + (261.25 kV) * (0.3937 x 10^-5/2)

We can assume the receiving end current (IR) = S / (sqrt(3) * VR * p.f) = 550 * 10^6 / (sqrt(3) * 261.25 kV * 0.99) = 1,924.43 A

Therefore, Vs = 276.32 kV

The receiving end voltage VR and current IR are 261.25 kV and 1,924.43 A respectively.

(iii) The sending end voltage Vs, current Is, and real power Ps:

Solving for Is and Ps: Is = IR * A + VR * B = 2,254.9 AVs = VR * A + IR * B = 276.32 k

VPS = 3 * VR * IR * pf = 162.7 MW.

Thus, sending end voltage, Vs = 276.32 kV, sending end currently, Is = 2,254.9 A, and real power, Ps = 162.7 MW.

(iv) Transmission line efficiency at full load:

The transmission line efficiency (η) can be calculated as follows:

η = (P_r / P_s) * 100% where, P_r = Received Power and P_s = Sent Power P_r = 550 MW * 0.99 = 544.5 MWP_s = 3 * Vs * Is * pf = 3 * 276.32 kV * 2,254.9 A * 0.99 = 1,678.8 MW.

Therefore, η = (544.5 / 1678.8) * 100% = 32.4%

b) A 25 kV synchronous generator is generating 415 MW. The magnitude of the terminal voltage of the generator is 1.0 pu and the magnitude of the internal EMF (electromotive force) induced in the windings is 1.4 pu. The reactance of the generator is 1.0 pu on a 500 MW base. The relationships between the active and reactive power flow with the generator's voltage and load angle are provided in the equations below:

E_V/E cos δ = P/ EV sin δ = Q/ X

Given: Internal EMF, E = 1.4 pu,

Terminal voltage, V = 1 pu

Synchronous reactance, X = 1 pu

Generating power, P = 415 MW

(i) The load angle, ō, of the generator:

Active power, P = EV cos

δ415 * 10^6 = 1.4 * 1 * cos(δ)

cos(δ) = 0.415 / 1.4 = 0.2964

Load angle, δ = cos^-1 (0.2964)

Load angle, ō = 105.57 degrees

(ii) The per-unit reactive power flowing at the terminals of the generator: Reactive power, Q = EV sinδQ = 1.4 * 1 * sin(105.57) = 1.4489 pu

Per-unit reactive power, Q = 1.4489 pu

(iii) The power factor and phase angle 8: Power factor,

pf = P / S = 0.8565

pf = cos(8)cos(8) = 0.8565

Angle 8 = cos^-1(0.8565)

Angle 8 = 30.46 degrees

Therefore, the power factor is 0.8565 and the phase angle is 30.46 degrees.

Answers

To simulate the waveforms Vo and VR for different values of firing angle α (45° and 90°) and inductance L (0.0265 H, 0.265 H, and 530 mH) in PSIM, a simulation setup needs to be created. The firing angle α determines the conduction period of the thyristor, while the inductance L affects the current and voltage waveforms in the circuit. By simulating each combination of α and L, the waveforms Vo and VR can be observed and analyzed.

To perform the simulation in PSIM, start by creating a circuit with the appropriate components, including a thyristor, resistor, and inductor. Connect the input voltage source Vm, set the firing angle α, and specify the value of inductance L according to the desired simulation case.
Run the simulation for each combination of α and L and observe the waveforms of Vo (output voltage) and VR (voltage across the resistor). Analyze the waveforms to understand the effect of the firing angle and inductance on the circuit performance.
For a firing angle of α=45°, the thyristor will conduct for a shorter period compared to α=90°, resulting in a different waveform shape and voltage magnitude for Vo and VR. The inductance value (0.0265 H, 0.265 H, or 530 mH) will affect the current and voltage response, potentially introducing ripple or smoothing out the waveform depending on the value.
By simulating each combination of α and L, you can observe and analyze the waveforms to understand the behavior of the circuit under different conditions. This will help you gain insights into the impact of the firing angle and inductance on the output voltage and voltage across the resistor.

The correct option to find the value of the third bit from the right (bitNum = 2) of variable x is: int bit = (x >> 2) & 1;

To find the value of a specific bit in a variable, we need to perform a bitwise right shift operation followed by bitwise AND operation.

In option b, (x >> 2) performs a bitwise right shift by 2 positions, which moves the desired bit (bitNum = 2) to the rightmost position. Then, & 1 performs a bitwise AND with 1, which masks all the bits except the rightmost bit.

The result of (x >> 2) & 1 will be either 0 or 1, representing the value of the third bit from the right.

In a BJT Common Emitter Configuration Operation(npn), how do I know that the transistor is biased in the active region?

Answers

The datasheet or specifications of the specific transistor being used to determine the appropriate biasing conditions for the active region.

In a BJT (Bipolar Junction Transistor) Common Emitter Configuration with an npn transistor, the transistor is biased in the active region when both the base-emitter junction and the base-collector junction are forward-biased.

To determine if the transistor is biased in the active region, you need to check the voltages applied to the transistor terminals:

1. Base-Emitter Junction: The base-emitter junction should be forward-biased. This means that the base terminal (B) should be at a higher potential than the emitter terminal (E), typically by around 0.6 to 0.7 volts for silicon transistors. You can measure the voltage across the base-emitter junction using a multimeter.

2. Base-Collector Junction: The base-collector junction should also be forward-biased. This means that the collector terminal (C) should be at a higher potential than the base terminal (B), typically by several volts. The voltage across the base-collector junction can also be measured using a multimeter.

If both the base-emitter and base-collector junctions are forward-biased, it indicates that the transistor is biased in the active region. In the active region, the transistor operates as an amplifier, and small changes in the base current can result in significant changes in the collector current.

It's important to note that the biasing conditions may vary depending on the specific transistor and the desired operating point. The values mentioned above (0.6 to 0.7 volts for Vbe) are typical values for silicon transistors but can vary for different transistor types. Therefore, it's recommended to refer to the datasheet or specifications of the specific transistor being used to determine the appropriate biasing conditions for the active region.

Gold has 5.82 × 108 vacancies/cm3 at equilibrium at 300 K. What fraction of the atomic sites is vacant at 600 K? Given that the density of gold is 19.302 g/cm3, atomic mass 196.97 g/mol and the gas constant, R = 8.314 J/(mol K).

Answers

The fraction of vacant atomic sites in gold at 600 K can be calculated using the concept of equilibrium vacancy concentration and the Arrhenius equation. At 300 K, gold has an equilibrium vacancy concentration of 5.82 × 10^8 vacancies/cm^3. To determine the fraction of vacant sites at 600 K, we need to calculate the new equilibrium vacancy concentration at this temperature.

The Arrhenius equation relates the rate constant of a reaction to temperature and activation energy. In the case of vacancy concentration, it can be used to determine how the concentration changes with temperature. The equation is given as:

k = A * exp(-Ea / (R * T))

Where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin.

Since the equilibrium vacancy concentration is reached at both 300 K and 600 K, the rate constants at these temperatures can be equated:

A * exp(-Ea / (R * 300)) = A * exp(-Ea / (R * 600))

The pre-exponential factor A and the activation energy Ea cancel out, leaving:

exp(-Ea / (R * 300)) = exp(-Ea / (R * 600))

Taking the natural logarithm of both sides, we have:

-Ea / (R * 300) = -Ea / (R * 600)

Simplifying further:

1 / (R * 300) = 1 / (R * 600)

300 / R = 600 / R

300 = 600

This equation is not valid, as it leads to an inconsistency. Therefore, the assumption that the equilibrium vacancy concentration is reached at both temperatures is incorrect.

In conclusion, the calculation cannot be performed as presented, and the fraction of vacant atomic sites in gold at 600 K cannot be determined based on the information provided.

Answers

The Hamiltonian and energies for free and confined particles differ due to the presence of constraints and potential barriers in the case of a confined particle. The energies for a confined particle are discrete because its motion is restricted by the boundaries of the box, leading to specific standing wave patterns and quantized energy levels.

1. The Hamiltonian for a free particle and a confined particle in a box differs in terms of the potential energy term. For a free particle, the potential energy term is zero since there are no constraints on its movement. In contrast, for a confined particle in a box, the potential energy term represents the potential barrier created by the box's boundaries.

2. The energies for free and confined particles also differ. In the case of a free particle, the energy is continuous and can take on any value within a range. However, for a confined particle in a box, the energy levels are quantized, meaning they can only take on specific discrete values. These discrete energy levels correspond to different standing wave patterns within the box.

3. The energies for a confined particle are discrete because the particle's motion is restricted by the boundaries of the box. According to the particle-in-a-box model, the wave function of the particle must satisfy certain boundary conditions, resulting in standing wave patterns within the box. Only specific wavelengths, or frequencies, can fit within the box and form standing waves. Each standing wave pattern corresponds to a specific energy level, and since the number of possible standing wave patterns is finite, the energy levels are discrete.

Due to some design inadequacies the bridge failed while in construction. Evaluate with reference to this case whether there will be a legal entitlement (cite relevant article of tort case that can be levied against the engineer incharge in this case)

Answers

In the given scenario, if the bridge failed due to design inadequacies and the engineer in charge was responsible for the design and estimation, there may be a potential legal entitlement against the engineer under the principles of professional negligence in tort law.

The legal entitlement that can be levied against the engineer in charge in this case is professional negligence. Professional negligence occurs when a professional fails to exercise a reasonable standard of care, skill, or diligence in performing their duties, resulting in harm or damage to another party. In this situation, the engineer's role was crucial in the design and estimation of the bridge, and the failure during construction suggests that there were design inadequacies.

To establish a claim of professional negligence, certain elements need to be proven. Firstly, it must be demonstrated that the engineer owed a duty of care to the client or the parties affected by the construction of the bridge. This duty is typically established by the professional relationship between the engineer and the client.

Secondly, it must be shown that the engineer breached the duty of care by failing to meet the standard of care expected from a reasonable professional in the same field. The design inadequacies leading to the bridge failure would likely serve as evidence of this breach.

Lastly, it needs to be established that the breach of duty caused harm or damage to the client or other parties involved in the construction project. The failure of the bridge during construction would likely result in financial losses, delays, and potential safety risks.

To determine the specific legal entitlement or the relevant tort case that could be levied against the engineer, it would be necessary to consult the applicable laws and regulations in the jurisdiction where the incident occurred. Tort laws can vary by jurisdiction, so a specific article or case reference cannot be provided without knowing the specific jurisdiction involved.

What is a measure of the ability of a generator to keep a constant voltage at its terminals as a load varies?

Answers

The measure of a generator's ability to maintain a constant voltage at its terminals as the load varies is known as voltage regulation. It indicates how well a generator can maintain a stable output voltage despite changes in the connected load.

Voltage regulation is a critical parameter for generators, as it directly affects the quality and stability of the electrical power they supply. It quantifies the generator's ability to maintain a steady voltage level at its terminals under different load conditions. Voltage regulation is typically expressed as a percentage and can be classified into two types: positive voltage regulation and negative voltage regulation.

Positive voltage regulation refers to a generator's ability to increase its output voltage as the load increases. This ensures that the voltage at the terminals remains relatively constant, compensating for voltage drops caused by increased load demands. On the other hand, negative voltage regulation occurs when the generator's output voltage decreases as the load increases. In this case, the generator may struggle to maintain a consistent voltage level, resulting in voltage drops and potential power quality issues.Voltage regulation is achieved through various techniques, including the use of automatic voltage regulators (AVRs) and voltage control systems. These systems continuously monitor the generator's output voltage and adjust the field current or excitation system to maintain a desired voltage level. By closely regulating the generator's voltage, the system ensures a stable power supply that meets the requirements of the connected load.

In summary, voltage regulation is a crucial measure of a generator's performance, indicating its ability to provide a consistent voltage output as the load varies. By effectively controlling voltage fluctuations, generators with good voltage regulation contribute to stable power distribution, enhanced equipment performance, and overall system reliability.

To determine the roots of the given polynomial using the Routh-Hurwitz stability criterion, we first need to construct the Routh array. The polynomial is:

A(s) = s^6 + 4s^5 + 12s^4 + 16s^3 + 41s^2 + 36s + 72

The Routh array is constructed as follows:

Row 1: [1, 12, 41]

Row 2: [4, 16, 36]

Row 3: [16, 36]

Row 4: [36]

Now, we calculate the remaining rows of the Routh array:

Row 3: [16, 36] - (12/1) * [4, 16, 36] = [16, 36 - 48, 0] = [16, -12, 0]

Row 4: [36] - (16/1) * [16, -12, 0] = [36 - 256, -12 * 16, 0] = [-220, -192, 0]

The Routh array is as follows:

Row 1: [1, 12, 41]

Row 2: [4, 16, 36]

Row 3: [16, -12, 0]

Row 4: [-220, -192, 0]

The number of sign changes in the first column is 3. According to the Routh-Hurwitz criterion, the number of roots with positive real parts is equal to the number of sign changes in the first column. Since there are 3 sign changes, there are 3 roots with positive real parts.

Therefore, the polynomial has 3 roots with positive real parts and the remaining roots have negative real parts. The Routh-Hurwitz criterion does not provide the actual values of the roots, only the number of roots with positive real parts.

In conclusion, based on the Routh-Hurwitz stability criterion, the given polynomial has 3 roots with positive real parts and the remaining roots have negative real parts.

It is implemented widely in industries such as automotive, mining, dredging, oil refining, pulp and paper manufacturing, chemical processing and power generating plants. Process Control Instrumentation monitors the state of a process parameter, detecting when it varies from desired state, and taking action to restore it. Control can be discrete or analog, manual or automatic, and periodic or continuous. Some terms that are commonly used in describing control systems are defined below.

The vacuum cleaner is a household appliance which has been with us in one form or another for over 150 years. Before its invention, removing dust from rugs and carpets was a difficult and dirty process, which involved taking them outside and hitting them with a device that looked like a tennis racket. Although this was usually done several times a year, it was not very effective, and health problems caused by dust and dirt were very common.In 1869, an American named Ives McGaffey produced a device that effectively removed dust from carpets but made the air very dusty. Ten years later, another American, Melville Bissell created a similar device, but it was better at catching the dust. Unfortunately, both were heavy and expensive, and the public didnt believe that they did a good job. As a result, only a few people bought them.In 1899, John Thurman became the first person to invent a vacuum cleaner with a petrol engine. Shortly afterwards, he set up a house cleaning business, charging people to clean their homes. This idea was so unusual and exciting that people invited their friends over for vacuum parties, and Thurman became rich as a result. Two years later, a Londoner, Hubert Cecil Booth, improved Thurmans device by replacing the petrol engine with an electric motor.The biggest problem with these early powered vacuum cleaners was they were very big, and also needed two or three skilled professionals to work them. Finally, in 1908, another American, James Spangler produced a portable electric vacuum cleaner that could be used by everybody. He later sold the design to his uncle, William Hoover, whose company became the worlds most famous manufacturer of vacuum cleaners. Today, more than 100 years later, people still say a hoover when they mean a vacuum cleaner, even though other manufacturers such as Dyson now have a bigger share of the world market.Q2.
