A projectile of mass m = 0.1 kg is launched vertically upward with a initial speed of v(0) = 8 m/s, its speed decreases due to the effect of gravity and also due to the air resistance, and is modeled with the differential equation:

Answers

Answer 1

This is the solution to the differential equation.

The height of the projectile can be determined by plugging in values for t, g, k, m, and v(0).

A projectile is an object that is thrown into the air with some initial velocity and moves under the influence of gravity. The motion of a projectile is governed by its mass, the initial velocity and the gravitational force acting on it.

The motion of a projectile can be modeled by a second order differential equation.

In this case, we have a projectile of mass m=0.1 kg that is launched vertically upward with an initial speed of v(0)=8 m/s. The speed of the projectile decreases due to the effect of gravity and air resistance.

This can be modeled by the differential equation: [tex]d2y/dt2 = -g - k/m dy/dt[/tex]

where y(t) is the height of the projectile at time t, g is the acceleration due to gravity,

k is the air resistance coefficient, and dy/dt is the velocity of the projectile at time t.

Substituting this into the second equation above, we get: [tex]dy/dt = (-g/k) + Ce^(-kt/m)[/tex]

Integrating both sides, we get:[tex]y(t) = (-gt/k) + (Cm/k) (1 - e^(-kt/m))[/tex]

where Cm = m(v(0) + g/k).

A 5 m high rectangular concrete column with cross section size of 500 mm x 500 mm is reinforced by ten 30 mm diameter steel bars. A compressive load of 1500 kN is applied to the column. Take elastic modulus of steel E, as 200 GPa and elastic modulus of concrete Ec as 30 GPa. (a)  Determine the shortening of the column. (b) If the compressive strength of the concrete is 30 MPa, would the concrete in the column fail under the applied load?

Answers

Since 6 N/mm² is less than 30 N/mm², the concrete in the column would not fail under the applied load.

(a) To determine the shortening of the column, we can use the concept of axial deformation and strain.

Given:

Height of the column (L) = 5 m

Cross-sectional area of the column (A) = 500 mm x 500 mm

= 0.5 m x 0.5 m

= 0.25 m²

Number of steel bars (n) = 10

Diameter of steel bars (d) = 30 mm

Compressive load (P) = 1500 kN

= 1500,000 N

Elastic modulus of steel (E) = 200 GPa

= 200,000 MPa

Elastic modulus of concrete (Ec) = 30 GPa

= 30,000 MPa

First, we need to calculate the stress in the column:

Stress (σ) = P / A

Next, we calculate the strain in the concrete:

Strain (εc) = σ / Ec

The shortening of the column can be calculated using the strain and the original height:

Shortening (ΔL) = εc * L

Substituting the values:

σ = 1500,000 / 0.25

= 6,000,000 N/m²

= 6 MPa

εc = 6 MPa / 30,000 MPa

= 0.0002

ΔL = 0.0002 * 5

= 0.001 m

= 1 mm

Therefore, the shortening of the column is 1 mm.

(b) To determine if the concrete in the column would fail under the applied load, we need to check if the compressive stress exceeds the compressive strength of concrete.

Given:

Compressive strength of concrete (f'c) = 30 MPa

= 30 N/mm²

If the stress in the column (σ) is greater than the compressive strength of concrete, then the concrete would fail.

σ = 6 MPa

= 6 N/mm²

Since 6 N/mm² is less than 30 N/mm², the concrete in the column would not fail under the applied load.

Therefore, the concrete in the column would not fail.

Discuss the following: a. The basic acoustic criteria for Auditorium Acoustical design
b. The hearing conditions in any auditorium which could be affected by purely architectural considerations:

Answers

The basic acoustic criteria for auditorium acoustical design include reverberation time, clarity, and sound distribution. The hearing conditions in an auditorium that can be affected by purely architectural considerations include direct sound, early reflections, and diffusion.

a. The basic acoustic criteria for Auditorium Acoustical design:
1. Reverberation Time: Reverberation time refers to the length of time it takes for sound to decay by 60 decibels after the source stops. In an auditorium, the appropriate reverberation time is determined by the type of performance or activity taking place. For example, a concert hall may require a longer reverberation time to enhance the richness and fullness of music, while a lecture hall may require a shorter reverberation time to ensure speech intelligibility.
2. Clarity: Clarity is the ability to hear and understand speech or music with distinctiveness and intelligibility. It is influenced by factors such as the design of the auditorium, the positioning of reflective surfaces, and the absorption of sound waves. To achieve good clarity, it is important to minimize echoes and unwanted reflections that can cause speech or music to become muffled or distorted.
3. Sound Distribution: Sound distribution refers to the evenness of sound throughout the auditorium. It is essential to ensure that every seat in the auditorium receives an equal level of sound, without any significant variations in volume or tonal quality. Proper placement of speakers, careful consideration of room dimensions, and appropriate use of reflective and absorptive materials can help achieve balanced sound distribution.

b. The hearing conditions in any auditorium which could be affected by purely architectural considerations:
1. Direct Sound: Direct sound is the sound that travels directly from the source (such as a speaker or performer) to the listener without being reflected by any surfaces. Architectural considerations, such as the placement of speakers and the orientation of the stage, can impact the direct sound experience for the audience. Proper placement and aiming of speakers can ensure that the direct sound reaches every listener effectively.
2. Early Reflections: Early reflections are the first reflections of sound waves off the surfaces of the auditorium, such as walls, ceiling, and floor. These reflections can significantly impact sound quality and intelligibility. The architectural design should consider minimizing or controlling these early reflections to avoid any unwanted effects, such as echoes or speech distortion.
3. Diffusion: Diffusion refers to the scattering of sound waves in different directions, creating a sense of spaciousness and envelopment in the auditorium. Architectural considerations, such as the shape and design of the walls and ceiling, can influence the diffusion of sound. Careful design can help create a balanced and immersive listening experience for the audience.

Thabo's statement is incorrect. The correct formula for the function illustrated in the table is not y = 5x + 10.

To determine if Thabo's statement is correct, we need to compare the given function y = 5x + 10 with the values in the table.

Let's evaluate the given function for each x-value in the table and compare it to the corresponding y-value:

For x = 1:

y = 5(1) + 10

y = 5 + 10

y = 15

For x = 2:

y = 5(2) + 10

y = 10 + 10

y = 20

For x = 3:

y = 5(3) + 10

y = 15 + 10

y = 25

For x = 4:

y = 5(4) + 10

y = 20 + 10

y = 30

Comparing the calculated values with the y-values given in the table, we have:

Here, the main objective is to purify an API by means of a cooling crystallisation process. Since filtration of small particles can be problematic, a seeded batch cooling crystallisation process should be developed that avoids nucleation.
Demonstrate that the steady state number density distribution can be analytically determined to be a decaying exponential function.

Answers

The steady-state number density distribution can be determined analytically to be a decaying exponential function by examining the results of cooling crystallization processes that seek to purify an active pharmaceutical ingredient (API).

One key aspect of this approach is to use a seeded batch cooling crystallization process that avoids nucleation since filtration of small particles can be problematic.During the crystallization process, nucleation is a major hurdle, and it frequently contributes to the production of tiny particles in the process stream. These small particles could be difficult to filter out later on, leading to downstream processing issues.

To avoid the nucleation, seeded batch cooling crystallization is used, which is a well-known crystallization technique. The method of seeded batch cooling crystallization is to introduce small crystals into the solution and gradually cool it. The solution gets supersaturated, leading to crystal growth while avoiding the creation of additional crystals.

The temperature of the solution is reduced until the growth of the crystal stops when all the solute has crystallized.The growth kinetics of the crystals in the seeded batch cooling crystallization can be analyzed and modeled, and a steady-state number density distribution can be determined analytically.

In such a distribution, the steady-state number of crystals per unit volume can be described by a decaying exponential function. Therefore, the steady-state number density distribution can be analytically determined to be a decaying exponential function.

The seeded batch cooling crystallization process can be used to purify the API. Additionally, the steady-state number density distribution can be determined analytically to be a decaying exponential function.

The accepted Critical Reynolds Number for a flat plate that allows determining the transition from laminar to turbulent flow that has occurred in the boundary layer is 5 x 10¹.

The Reynolds number is a dimensionless value used in fluid mechanics to predict whether the flow of a fluid will be laminar or turbulent. The transition from laminar to turbulent flow depends on the Reynolds number.The Reynolds number for a flat plate can be given as Re = (ρvd) / μWhere:ρ is the density of the fluid, v is the velocity of the fluid, d is the distance, and μ is the dynamic viscosity of the fluid.

If the Reynolds number is below a critical value, the flow will be laminar. If the Reynolds number is above this critical value, the flow will be turbulent. For a flat plate, this critical value is approximately 5 x 10¹ (Re=5x10¹). Therefore, option (d) is the correct answer.

x² + 6x + 10 / (x + 1)²(x + 2) = A / (x + 1) + B / (x + 1)² + C / (x + 2),

where A, B, and C are the coefficients that need to be determined. By multiplying both sides of the equation by the denominator, we can find a common denominator and equate the numerators. The resulting equation will allow us to solve for the coefficients A, B, and C, which will complete the partial fraction decomposition.

Arif wants to buy some mangoes and apples. He has 122tk. Price of each mango is 7tk and each apple is 12tk. How many mangoes and apples he can buy?

Answers

Let the number of mangoes that Arif buys be m. Similarly, let the number of apples that Arif buys be a. Since the price of each mango is 7tk and each apple is 12tk, therefore: 7m + 12a = 122   -------- (1)

Also, since the number of mangoes and apples must be a whole number, therefore, both m and a must be integers.

From equation (1),

7m + 12a = 122

We can write:

7m = 122 - 12a

If we substitute m = 0, 1, 2, 3, .... in the above equation, we can get the values of a that satisfy the equation.

When m = 0, then 12a = 122, which is not possible, since a should be a whole number.

When m = 1, then 7 + 12a = 122, which gives a = 9.

When m = 2, then 14 + 12a = 122, which gives a = 8.

When m = 3, then 21 + 12a = 122, which is not possible, since a should be a whole number.

When m = 4, then 28 + 12a = 122, which is not possible, since a should be a whole number.

Hence, Arif can buy either 1 mango and 9 apples or 2 mangoes and 8 apples. Arif has a total of 122 taka. He wants to buy mangoes and apples and the cost of each mango is 7 taka and the cost of each apple is 12 taka. We are supposed to find out the number of mangoes and apples that Arif can buy with 122 taka. Let the number of mangoes be m and the number of apples be a. The cost of each mango is 7 taka and the cost of each apple is 12 taka. Therefore, the total cost of all the mangoes and all the apples will be:

7m + 12a

We are also given that Arif has a total of 122 taka, so we can write:

7m + 12a = 122   -------- (1)

Since both m and a must be integers, we can substitute different values of m and find the corresponding values of a that satisfy the above equation.

If m = 0, then we get 12a = 122, which is not possible, since a should be a whole number.

If m = 1, then we get 7 + 12a = 122, which gives a = 9.

If m = 2, then we get 14 + 12a = 122, which gives a = 8.

If m = 3, then we get 21 + 12a = 122, which is not possible, since a should be a whole number.

If m = 4, then we get 28 + 12a = 122, which is not possible, since a should be a whole number.

Therefore, Arif can buy either 1 mango and 9 apples or 2 mangoes and 8 apples.

Hence, Arif can buy either 1 mango and 9 apples or 2 mangoes and 8 apples with the total amount of 122 taka.

PROBLEMS 13-1. A residential urban area has the following proportions of different land use: roofs, 25 percent; asphalt pavement, 14 percent; concrete sidewalk, 5 percent; gravel driveways, 7 percent; grassy lawns with average soil and little slope, 49 percent. Compute an average runoff coefficient using the values in Table 13-2. 13-2. An urban area of 100,000 m² has a runoff coefficient of 0.45. Using a time of concentration of 25 min and the data of Fig. 13-1, compute the peak discharge resulting from a 10-year storm.

Answers

The peak discharge resulting from a 10-year storm is 1,800 cubic meters per second.

To compute the average runoff coefficient and the peak discharge resulting from a 10-year storm, we'll need to use the given proportions of different land use and the provided data.

Average Runoff Coefficient:

We are given the following proportions of different land use:

Roofs: 25%

Asphalt pavement: 14%

Concrete sidewalk: 5%

Gravel driveways: 7%

Grassy lawns: 49%

Using Table 13-2, we can find the corresponding runoff coefficients for each land use type. However, since the table is not provided in the given context, I won't be able to directly provide the exact values from the table. You would need to refer to Table 13-2 to find the respective runoff coefficients for each land use type.

Once you have the runoff coefficients for each land use type, you can calculate the average runoff coefficient by taking the weighted average of the runoff coefficients based on the proportion of each land use type.

For example, if we assume the respective runoff coefficients for each land use type are:

Roofs: 0.80

Asphalt pavement: 0.90

Concrete sidewalk: 0.85

Gravel driveways: 0.70

Grassy lawns: 0.30

Then, the average runoff coefficient can be calculated as follows:

Average Runoff Coefficient = (0.25 * 0.80) + (0.14 * 0.90) + (0.05 * 0.85) + (0.07 * 0.70) + (0.49 * 0.30)

Please substitute the respective runoff coefficients from Table 13-2 and calculate the average runoff coefficient using the provided proportions of land use.

Peak Discharge Resulting from a 10-Year Storm:

To compute the peak discharge resulting from a 10-year storm, we need the time of concentration and the runoff coefficient.

Given:

Area: 100,000 m²

Runoff Coefficient: 0.45

Time of Concentration: 25 min

We can use the Rational Method to calculate the peak discharge. The Rational Method equation is as follows:

Q = (C * A) / T

where:

Q is the peak discharge (in cubic meters per second)

C is the runoff coefficient

A is the area (in square meters)

T is the time of concentration (in minutes)

Substituting the given values:

Q = (0.45 * 100,000) / 25

Q = 1,800 cubic meters per second

Therefore, the peak discharge resulting from a 10-year storm is 1,800 cubic meters per second.

Checking the height-thickness ratio of masonry members D. Examples 2. The longitudinal wall of a single-span house is the pilaster wall with the spacing of two adjacent pilasters equal to 4m. There is a window with the width of 1.8m between two pilasters and the height of pilaster is 5.5m. The house is taken as the rigid-elastic scheme. Check the height-thickness ratio of the pilaster wall (the grade of mortar is M2.5). 240 tozot 2200

Answers

The height-thickness ratio of the pilaster wall in the given example should be checked to determine if it meets the required standard and design specifications, which cannot be determined based on the information provided.

To check the height-thickness ratio of the pilaster wall, we need to calculate the height and thickness of the wall and then compare their ratio to the specified limit.

Spacing between adjacent pilasters = 4m

Width of the window = 1.8m

Height of the pilaster = 5.5m

Grade of mortar = M2.5.

To calculate the thickness of the pilaster wall, we subtract the width of the window from the spacing between adjacent pilasters:

Thickness of the wall = Spacing - Width of window = 4m - 1.8m = 2.2m

Now, we can calculate the height-thickness ratio:

Height-thickness ratio = Height of pilaster / Thickness of wall = 5.5m / 2.2m = 2.5

Comparing the height-thickness ratio to the specified limit, which is not mentioned in the given information, we cannot make a definitive conclusion without knowing the specified limit.

The provided information does not mention any specific limit or criteria for the height-thickness ratio.

Calculate the depth of the neutral axis of the cracked section in mm.

Answers

The depth of the neutral axis of the cracked section in mm is 319.05.

Given data:

Length of rectangular reinforced concrete beam, L = 7.0 m

Width of rectangular reinforced concrete beam, b = 300 mm

Height of rectangular reinforced concrete beam, h = 550 mm

Self-weight of beam = 25 kN/m

Uniform dead load = 10 kN/m

Uniform live load = 10 kN/m

Compressive strength of concrete, f_c = 21 MPa

Tensile strength of steel, f_y = 415 MPa3-32 mm steel is used as tension steel,

area of steel = 3.14 x (32/2)^2 x 3 = 2412.96 mm

Stirrup diameter, φ = 12 mm

Clear cover, c = 40 mm

A = b x hA = 300 x 550A = 165000 mm2

Let's consider two cases to calculate depth of the neutral axis of the cracked section.

Case 1: x ≤ 0.85d

Let's assume the depth of the neutral axis of the cracked section, x = 0.85d

= 0.85 x 530

= 450.5 mm

Let's calculate depth of the compression zone, a = (m / (m + 1)) x xa

= (59.29 / (59.29 + 1)) x 450.5a

= 444.31 mm

Let's calculate compressive force, C from the below equation

C = 0.85 x f_c x b x aa

= depth of the compression zone

= 444.31 mm

C = 0.85 x 21 x 300 x 444.31

C = 2686293.45 N

T = 0.87 x f_y x As / (d - a/2)

As = area of steel

=2412.96 mm

2T = 0.87 x 415 x 2412.96 / (530 - 444.31/2)T

= 3261193.42 N

From the below equation, let's calculate the depth of the neutral axis of the cracked section.

M_r = T (d - Asfy / (0.85f_c b)) + (0.75 x fy x As x a/2)

M_r = 577115287.97 N.mm

T = 2361068.53

NAs = 2412.96 mm

2fy = 415

MPaf_c = 21

MPab = 300 mm

Substitute the given values in the above equation,

577115287.97 = 2361068.53 (d - 2412.96 x 415 / (0.85 x 21 x 300)) + (0.75 x 415 x 2412.96 x 467.41 / 2)

Simplify the above equation and solve for d, we get, d = 337.82 mm

consider the four compounds pentanol, ethane ,dimethyl ether 1,
4 butanediol.which compound would have the highest solubility in water and why?

Answers

1,4-butanediol would have the highest solubility in water due to the presence of hydroxyl groups, molecular weight, and polarity.



The compound with the highest solubility in water would be 1,4-butanediol.

Here's why:

1. Hydrogen bonding: 1,4-butanediol contains multiple hydroxyl (-OH) groups, which can form hydrogen bonds with water molecules. Hydrogen bonding is a strong intermolecular force that enhances solubility in water. Pentanol also contains an -OH group, but it has a longer carbon chain, making the hydroxyl group less accessible to form hydrogen bonds with water molecules.

2. Molecular weight: 1,4-butanediol has a molecular weight of 90 g/mol, which is relatively lower compared to the other compounds. Generally, compounds with lower molecular weights have higher solubility in water because they can be more easily surrounded and dispersed by water molecules.

3. Polarity: 1,4-butanediol is a polar compound due to the presence of the hydroxyl groups. Water is also a polar molecule. Like dissolves like, so polar compounds tend to dissolve well in polar solvents like water.

On the other hand, ethane and dimethyl ether 1 have lower solubility in water. Ethane is a nonpolar molecule, lacking any functional groups that can interact with water molecules. Dimethyl ether 1 is also nonpolar and has a lower molecular weight than 1,4-butanediol, but it lacks the hydroxyl groups that contribute to hydrogen bonding.

In summary, 1,4-butanediol would have the highest solubility in water due to the presence of hydroxyl groups, molecular weight, and polarity.

What is the moisture content of the wood sample of mass 21.5 g and after drying has a mass of 17.8 g?

Answers

The moisture content of the wood sample is approximately 17.21%.

To calculate the moisture content of the wood sample, you need to find the difference in mass before and after drying, and then divide it by the initial mass of the sample. The formula to calculate moisture content is:

Moisture Content = ((Initial Mass - Dry Mass) / Initial Mass) * 100

Let's calculate it for your wood sample:

Initial Mass = 21.5 g

Dry Mass = 17.8 g

Moisture Content = ((21.5 g - 17.8 g) / 21.5 g) * 100

Moisture Content = (3.7 g / 21.5 g) * 100

Answers

Given that the concentration of benzene in the drinking water supply is 5 mg/L, and assuming adults drink 2 L of water per day and children drink 1 L of water per day, we can calculate the daily intake of benzene for adults and children.

What is the daily intake of benzene for adults?

For adults, the daily intake of benzene can be calculated by multiplying the benzene concentration in water (5 mg/L) by the volume of water consumed (2 L/day). Therefore, the daily intake of benzene for adults is:

\[ \text{Daily Intake (adults)} = \text{Benzene concentration} \times \text{Water consumption (adults)} \]

\[ = 5 \, \text{mg/L} \times 2 \, \text{L/day} \]

For children, the daily intake of benzene can be calculated in a similar way. Since children drink 1 L of water per day, the daily intake of benzene for children is:

\[ \text{Daily Intake (children)} = \text{Benzene concentration} \times \text{Water consumption (children)} \]

\[ = 5 \, \text{mg/L} \times 1 \, \text{L/day} \]

A man who steals foodfrom another is shot down without mercy. But it is different in the case of the dogs. Should a man catch one, red-handed, gorging his last piece of bacon, he may not shoot him. If he does, the dog's owner can come down upon himfor his value as a draught-animal. A miners' meeting usually settles the amount. Nor is this any insignificant sum, forthe prices of sled dogs range from one to five hundred dollars, and in times of need as high as a thousand.Which best explains London's purpose for comparing the consequences of stealing for a man and for a husky?O London uses the comparison to persuade readers that huskies sometimes steal food from humans.O London uses the comparison to inform the reader that huskies are viewed as property worth money.O London uses the comparison to entertain the reader with a story about a husky that stole bacon.O London uses the comparison to inform the reader that humans and huskies are treated as equals. Accounting for the Establishment of a New Business (the Accounting Cycle) LO2, 2-5, 2-6 Penny Cassidy has decided to start her business, Penny's Pool Service \& Supply, Inc. (PPSS). There is much to do when starting a new business. Here are some transactions that have occurred in PPSS in March. a. Received $25,000 cash and a large delivery van with a value of $36,000 from Penny, who was given 4,000 shares of \$0.05 par value common stock in exchange. b. Purchased land with a small office and warehouse by paying $10,000 cash and signing a 10-year note payable to the local bank for $80,000. The land has a value of $18,000 and the building's value is $72,000. Use separate accounts for land and buildings. c. Purchased new computer equipment from Dell for $2,500cash, and purchased other office equipment for $4,000, signing a note payable due in six months to the office equipment manufacturer. d. Hired a receptionist for the office at a salary of $1,500 per month; the receptionist will begin working for PPSS starting in April. e. Paid $1,000 on the note payable to the bank [in (b) above] at the end of March (ignore interest). f. Purchased short-term investments in the stock of other companies for $5,000 cash. g. Ordered $10,000 in inventory from Pool Corporation, Inc., a pool supply wholesaler, to be received in April. Required: 1. For each of the events (a) through (g), prepare journal entries if a transaction of the business exists, checking that debits equal credits. If a transaction does not exist, explain why there is no transaction for the business. 2. Create T-accounts and post each of the transactions to determine balances at March 31. Because this is a new business, beginning balances are $0. 3. Prepare a trial balance on March 31 to check that debits equal credits after the transactions are posted to the T-accounts. 4. From the trial balance, prepare a classified balance sheet (with current assets and current liabilities sections) at March 31 (before the beginning of operations in April). 5. For each of the events (a) through (g), indicate if it is an investing activity (I) or financing activity (F) and the direction ( + for increases; for decreases) and amount of the effect on cash flows using the following structure. Write NE if there is no effect on cash flows. 6. Calculate the current ratio at March 31. Round your answer to three decimal places. What does this ratio indicate about the ability of PPSS to pay its current liabilities? Consider two celestial objects with masses m 1and m 2with a separation distance between their centers r. If the separation distance r were to triple, what would happen to the magnitude of the force of attraction? It increases by a factor of 3. It decreases by a factor of 9. It decreases by a factor of 3. It remains unchanged. It decreases by a factor of 6 . 29. The fundamental storage unit is a bit which can be in an OFF or ON state.
