Use g = 9.8m/s2 and calculate the weight of 3 bricks of butter having a mass of half a kilo each
Answers
Answer:
This article deals with weight formula and its derivation. Weight refers to the force which acts on a body or object due to the effect of gravity. So, when an individual stands on a scale, the reading that appears is the weight. The more an individual weighs consequently means a higher reading on the scale. When an individual loses weight, he should think of it as lessening one’s force on the Earth due to gravity.
weight formula
What is Weight?
Simply speaking, weight refers to the force of gravity. Weight is certainly a force that acts on all bodies or objects at all times near a heavenly body such as the Earth. The Earth pulls all objects downward towards the center with a force of gravity. One can find the magnitude of the force of gravity by multiplying the magnitude of the acceleration due to gravity by the mass of the particular object.
Some books describe weight as a scalar quantity, the magnitude of the gravitational force. In contrast, some books refer to weight as a vector quantity, the gravitational force which acts on the object. Moreover, some experts explain weight as referring to the magnitude of the reaction force which is exerted on a body by various mechanisms. Also, these mechanisms keep the body in place.
The unit of measurement for weight is certainly that of force. This unit in the International System of Unit (SI) is the newton. The object with a mass of 1 kilogram would weigh about 9.8 Newtons on the Earth’s surface. Furthermore, it would weigh about one-sixth as much on the moon.
Weight Formula
The weight of an object or body certainly depends on the mass of the object and the gravity acting on it. This is why, the weight is different from mass. The mass of an object would be same whether on the Earth or on the Moon. The weight of an object due to the influence of gravity would be different on the Earth than on the Moon. The weight formula can be explained as follows:
Weight = mass × gravity
The formula for this is:
w = mg
Here we have,
w = weight
m = mass
g = gravity

Using the Breguet range and endurance equation, estimate the amount of kerosene
fuel needed for an aircraft weighing 10 metric tons (this is the dry weight that
includes passengers and cargo) to fly from Boston to Los Angeles, assuming a
distance of 5,000 [km], flying at 300 [m/s].
Assume a lift-to-drag ratio of 15 - this is the ratio of lift force over drag force during
the cruise, the overall efficiency of 0.3, and about half of the standard air density at
an altitude of approximately 6,000 [m]. You can neglect the climb and descent
phases of the flight. The energy density of kerosene is provided in Module 9, section
3: "The Breguet range and endurance equation". Why is this a tricky calculation?
Answers
The amount of kerosene fuel needed for an aircraft weighing 10 metric tons to fly from Boston to Los Angeles, assuming a distance of 5,000 [km] is 10000 kg.
What is Breguet equation?Breguet equation is used to determine the range of airplane fly in some specified set of parameters.
[tex]R=\dfrac{h_f}{g}\dfrac{L}{D}\times \eta \ln \left(\dfrac{W_{initial}}{W_{final}}\right)[/tex]
Here, (L/D) is lift to drag ratio, g is gravitation acceleration, h is height and W is weight.
The weight of aircraft is 10 metric tons (this is the dry weight that includes passengers and cargo) The distance of 5,000 [km], with velocity at 300 [m/s] from Boston to Los Angeles has to be cover by the airplane.
The initial weight is 10 metric tons or 10000 kg. Thus, the final weight with total fuel burn is,
[tex]W_{final}=W_{initial}-W_{fuel}\\W_{final}=1-\dfrac{W_{fule}}{W_{initial}}[/tex]
The lift-to-drag ratio is 15 and the overall efficiency is 0.3, The standard air density at an altitude of approximately 6,000 [m] is half.
Thus, put the values, in above formula,
[tex]5000=\dfrac{6000}{9.81}(15)\times(0.3) \ln \left(\dfrac{10000}{1-\dfrac{W_{fuel}}{10000}}}\right)\\[/tex]
[tex]\ln \left(\dfrac{10000}{1-\dfrac{W_{fuel}}{10000}}}\right)=1.8167\\\ln \left(\dfrac{1}{10000-W_{fuel}}}\right)=1.8167[/tex]
Solving this equation, we get,
[tex]W_{fuel}=10000\rm\; kg\\[/tex]
Thus, the amount of kerosene fuel needed for an aircraft weighing 10 metric tons to fly from Boston to Los Angeles, assuming a distance of 5,000 [km] is 10000 kg.

How to solve Binomial Probability?
The formula for binomial probability distribution is;
P(X = x) = ⁿCₓ × pˣ × (1 - p)⁽ⁿ ⁻ ˣ⁾
where;
x = total number of successes
p = probability of a success on an individual trial
n = number of trials
We are given;
x = 3

Reason for IEE regulations in electrical installation
Answers
Because doing electrical installations without regulations can lead to substandard work that can kill people and destroy property.
Explanation:
Prior to leaving Ohio, I was, for many years, a Certified Fire Safety Inspector. The prevention side of my job involved inspecting structures - houses, churches, schools, commercial, industrial, etc. - for compliance with fire safety regulations. I was required to have a working knowledge of the National Electrical Code, as well as most other building codes, so that I could identify conditions that could cause people to get hurt or buildings to catch fire.
The electrical code was considered to be a compilation of “best practices” for the installation of electrical systems in a structure. In many instances these “practices” were developed as a result of prior unsafe practices leading to fires and/or loss of life. Sort of - opps, we mustn’t do that again! The standards published concerning a wide range of electrical systems and devices, if followed, will make the installation as safe as the current state-of-the-art permits. Failure to follow the relevant codes can destroy a builder’s or an electrician’s defense in court if something bad happens.
As an example: 165 people died at the Beverly Hills Supper Club in Soulgate, KY, on May 28th 1977. The fire appeared to have started by improper electrical wiring. After the fire, numerous electrical code violations, as well as numerous building code violations were found. You wouldn’t want to be the owner of something like that.
Several new laws were passed as a result of this fire -no more aluminum wiring in commercial buildings, exit lighting required, automatic fire alarm systems, automatic sprinkler systems required, etc. The updates made to electrical and building codes made later buildings much safer.
As written, the IEEE codes are not law - after all the IEEE is an association, not a legislature; however, many of the standards they set forth are referenced specifically or by inclusion in formal codes approved by legislative bodies and made into law - The Ohio Fire Code, for example references the National Electrical Code. An inspector noting violations of such codes when they are given legal recognition by the State can issue orders to have violations corrected and can also issue citations which can lead to court appearances and monetary fines levied against the building’s management.
Codes are updated with regularity. In general, a change to the code does not require a change to an existing structure. However, if a structure undergoes renovation then there is a point at which the building must be brought up to meet the present code standards. There are exceptions. Much time, effort , and money has been expended to remove asbestos from existing structures even where no renovation to the structure was even being planned. Exit doors opening to the public way now need automatic EXIT lighting and many older buildings were retrofit with exit lighting as a result in code updates.
Codes are for a reason. They are devised by the collective thinking and experience of people who are experts - or at least experienced - in their field. And they are intended to protect YOU!

A compressible clay layer has a thickness of 3.8 m. After 1.5 yr, when the clay is 50% consolidated, 7.3 cm of settlement has occurred. For a similar clay and loading conditions, how much settlement would occur at the end of 1.5 yr and 5 yr if the thickness of this new layer were 38 m
Answers
The amount of settlement that would occur at the end of 1.5 year and 5 year are 7.3 cm and 13.14 cm respectively.
How to determine the amount of settlement?For a layer of 3.8 m thickness, we were given the following parameters:
U = 50% = 0.5.Sc = 7.3 cm.For Sf, we have:
Sf = Sc/U
Sf = 7.3/0.5
Sf = 14.6
Therefore, Sf for a layer of 38 m thickness is given by:
Sf = 14.6 × 38/3.8
Sf = 146 cm.
At 50%, the time for a layer of 3.8 m thickness is:
[tex]t_{50}[/tex] = 1.5 year.
At 50%, the time for a layer of 38 m thickness is:
[tex]t_{50}[/tex] = 1.5 × (38/3.8)²
[tex]t_{50}[/tex] = 150 years.
For a thickness of 38 m, U₂ is given by:
[tex]\frac{U_1^2}{U_2^2} =\frac{(T_v)_1}{(T_v)_2} = \frac{t_1}{t_2} \\\\U_2^2 = U_1^2 \times [\frac{t_2}{t_1} ]\\\\U_2^2 = 0.5^2 \times [\frac{1.5}{150} ]\\\\U_2^2 = 0.25 \times 0.01\\\\U_2=\sqrt{0.0025} \\\\U_2=0.05[/tex]
The new settlement after 1.5 year is:
Sc = U₂Sf
Sc = 0.05 × 146
Sc = 7.3 cm.
For time, t₂ = 5 year:
[tex]U_2^2 = U_1^2 \times [\frac{t_2}{t_1} ]\\\\U_2^2 = 0.5^2 \times [\frac{5}{150} ]\\\\U_2^2 = 0.25 \times 0.03\\\\U_2=\sqrt{0.0075} \\\\U_2=0.09[/tex]
The new settlement after 5 year is:
Sc = U₂Sf
Sc = 0.09 × 146
Sc = 13.14 cm.
