The theoretical density of diamond given that the C-C distance and bond angle are 0.154 nm and 109.5° respectively is; 3.54 g/cm³

The first thing we will do is to get the unit cell edge length from the given C - C distance.

From the structure of diamond;

Φ = ¹/₂ * bond angle

Φ = ¹/₂ * 109.5°

Φ = 54.75°

Thus;

θ = 90° - 54.75°

θ = 35.25°

Let the height from a point to the base of the cube of the structure be x. Thus;

x = a/4 = y sin θ

where a is unit cell edge length and y is C -C length. Thus;

a = 4y sin θ

a = 4 * (0.154 * 10⁻⁹) * sin 35.25°

a = 3.56 * 10⁻⁸ cm

The unit cell volume is;

V_c = a³

Thus; V_c = (3.56 * 10⁻⁸)³

V_c = 4.51 * 10⁻²³ cm³

Now, there are 8 equivalent atoms per unit cell and as such density is calculated from;

ρ = (n * A_c)/(V_c * N_a)

A_c is atomic weight of diamond = 12.01 g/mol

N_a is avogadro's number = 6.022 * 10²² atoms/g

Thus;

ρ = (8 * 12.01)/(4.51 * 10⁻²³ * 6.022 * 10²²)

ρ = 3.54 g/cm³

Explanation:

If this is a true or false question.

The discoloration is when the color of a particular thing comes off or changes, fading from its original color. In other words, when the original color of anything changes or wanes off, then that is called discoloration. The statement is true.

This chemical shift occurs for a number of reasons, including its interaction with other elements nearby or the unfavorable effects of other elements it comes into touch with.

Water leaks may create cases of discoloration on walls, surfaces, even ceilings, and pipes. As a result, the surface progressively changes and becomes moist.

Discoloration puts the surrounding region in danger in addition to altering the part(s) or area's look and durability.

Since a change in that region or component is required, the raw material(s) used are wasted. The claim that discoloration results in the waste of raw materials are thus accurate.

The model energy equation for a tank is given by Cp * dT/dt = (Q_in - Q_out) / (dm/dt * de/dm), considering energy balance, heater input, and heat transfer to the outside.

To derive the model energy equation for a tank, we can use the principle of energy balance. The energy balance equation for the tank can be written as follows:

Rate of energy accumulation inside the tank = Energy input - Energy output

The rate of energy accumulation inside the tank can be expressed as the product of the mass of the fluid inside the tank and the rate of change of its internal energy with respect to time (dm/dt * de/dm * de/dt).

The energy input to the tank comes from the heater, which generates heat. Let's denote the rate of heat generated by the heater as Q_in.

The energy output from the tank is the heat transfer to the outside. The rate of heat transfer to the outside is given by Q_out, which is related to the heat transfer coefficient (h), the surface area of the tank (A), and the temperature difference between the tank and the surroundings (T - T_surroundings).

Therefore, the energy balance equation for the tank can be written as:

dm/dt * de/dm * de/dt = Q_in - Q_out

Next, let's express the rate of change of internal energy (de/dt) in terms of temperature (T) using the specific heat capacity (Cp) of the fluid inside the tank. The rate of change of internal energy can be written as:

de/dt = Cp * dm/dt * dT/dt

Substituting this into the energy balance equation, we get:

dm/dt * de/dm * Cp * dm/dt * dT/dt = Q_in - Q_out

Simplifying the equation, we have:

Cp * dm/dt * dT/dt = (Q_in - Q_out) / (dm/dt * de/dm)

Finally, rearranging the equation, we obtain the model energy equation for the tank:

Cp * dT/dt = (Q_in - Q_out) / (dm/dt * de/dm)

This equation represents the rate of change of temperature inside the tank (dT/dt) as a result of the energy input from the heater (Q_in) and the energy output through heat transfer to the outside (Q_out). The specific heat capacity (Cp) of the fluid and the rate of change of mass (dm/dt) and internal energy (de/dm) are also considered in the equation.

An extremum is a point where the function has its highest or lowest value, and at which the slope is zero.

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum is as follows;

Reason:

The given parameters are;

Form of silo = Cylinder surmounted by a hemisphere

Cost of construction of hemisphere per square unit = 2 × The cost of of construction of the cylindrical side wall

Required:

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum

Solution:

The fixed volume of the silo, V, can be expressed as follows;

\(V = \pi \cdot r^2 \cdot h + \dfrac{2}{3} \cdot \pi \cdot r^3\)

Where;

h = The height of the cylinder

r = The radius of the cylinder

The surface area is, Surface Area = 2·π·r·h + 2·π·r²

The cost, C = 2·π·r·h + 2×2·π·r² = 2·π·r·h + 4·π·r²

Therefore;

\(C = 2 \times \pi \times r\times \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } + 4 \cdot \pi \cdot r^2 = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)

At the minimum value, we have;

Which gives;

16·π·r³ = 6·V

Which gives;

\(h = \dfrac{\dfrac{8 \cdot \pi \cdot r^3}{3} - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } = 2 \cdot r\)

h = 2·r

The height of the silo, h = 2 × The radius, 2

Therefore, the dimensions to be used if the volume is fixed and the cost is to be kept to a minimum is, height, h = 2 times the radius

Answer:

the percentage of light that gets through this combination is 9.38

Explanation:

Given the data in the question;

Let us represent the incident unpolarized light with \(I_0\).

So, the amount of light intensity passing through the first polarizer will be;

\(I_1\) = \(I_0\) / 2 ------ let this be equation 1

An the amount of light intensity passing through the second polarizer will be;

\(I_2\) = \(I_1\)cos²θ

given that; the second one has its transmission axis at 30°

so, we substitute;

\(I_2\) = \(I_1\) × cos²( 30° )

\(I_2\) = \(I_1\) × 0.75

\(I_2\) = 0.75\(I_1\)

from equation; \(I_1\) = \(I_0\) / 2

\(I_2\) = 0.75( \(I_0\) / 2 )

\(I_2\) = 0.375\(I_0\) .

Now, the amount of light intensity passing through the third polarizer will be;

\(I_3\) = \(I_2\)cos² ( 90° - 30° )

\(I_3\) = \(I_2\) × cos²( 60° )

\(I_3\) = \(I_2\)  × 0.25

we substitute

\(I_3\) = 0.375\(I_0\)  × 0.25

\(I_3\) = 0.09375\(I_0\)

∴ \(I_3\)/\(I_0\) × 100 = 0.09375 × 100

⇒ 9.38%

Therefore, the percentage of light that gets through this combination is 9.38

Explanation: so with out it you are wasting how ever much money you spent on your car

and When you think about automobile or automotive engineering, the first image you probably have is of engineers designing and working on sleek and wickedly fast sports cars. However, the fact is that this is a very limited view of what automobile engineers can do. This particular career path is actually quite interesting and exciting when you realize all that it encompasses. It isn’t just limited to creating the next Bugatti or Lamborghini.

Automobile engineers are dedicated to finding solutions for the challenges that we face when it comes to personal mobility. They look at how the current cars should look and feel, but that isn’t all they do. They are looking at mobility that is sustainable, auto-driven cars (they drive themselves and don’t need drivers) and even working out mobility on Mars.

Being an automobile engineer is no longer just limited to working on cars. Today, an automobile engineer has to design new vehicles and work on improving existing ones, become part of research and development in order to determine solutions to various engineering challenges and even engage in production which also means designing and planning the latest production processes. So how do they go about doing all of this?

They Need to Study

This is one of the first steps that an automotive engineer needs to take to enter this field. One of the more unique things about the automotive industry is that it is truly global. This means that if you are interested in this branch of engineering, you don’t have to focus on getting a degree from your own country. You can apply to study abroad and gain more exposure to a global industry. It will even increase your prospects in the international market.

You can start out by going for mechanical engineering or you can go for a very specific automotive engineering degree. In fact, if you don’t want to take the option of going to a university, you can even consider doing an apprenticeship instead. In order to be able to get into the appropriate course at college level, the subjects that you need to be looking at carefully are known as STEM or Science, Technology, Engineering and Maths.

Another part of your preparation is getting an internship, once you have started the course. You need to research the various companies properly and get the right internship. It can improve your knowledge and experience and really add to your resume.

They Need to Think Big

The automotive industry isn’t just about cars. It includes a plethora of other related industries, for example fuel specialists. So now if you step back and take a good look, you’ll realize that some of the biggest global giants belong to this particular field and as an automotive engineer you’ll have the chance to work for them. Many of these companies offer graduate programs through various universities, so if you want to get a Masters in this field while learning the ropes, you can do it.

They Need to Expand Their Horizons

The profession is global in a way few professions are. The fact is that automobile companies are present all over the world. This also means that there are different cultures and languages to deal with. As an automotive engineer, you will no longer work within the narrow bounds of simply your own culture. You will learn to communicate on a level that is completely global and respect and interact with cultures other than yours. Very simply put, this means that you’ll be expanding your linguistic skills and learning how to work and get along with people from diverse cultures and backgrounds. This is one of the reasons that your resume is greatly enhanced if you have work experience at an automobile enterprise.

There are some who might tell you that the future of this field isn’t exactly great. This, however, isn’t true. Considering all that the automotive industry encompasses from self-driving vehicles to creating new safety features or enhancing existing ones, there is plenty of scope for you to determine which direction you want to go in. This industry will teach you to be forward thinking, visionary and dynamic. You will learn to think creatively and look for out of the box solutions. When you stop to think about it, this field helps you grow as a person in a way that not many other industries or professions can do. theres you a giant answer

In exercise 13.8-1, the three different dimensioning approaches are unilateral, bilateral, and limit dimensioning. The total tolerance between point A and B varies for each approach.

For the unilateral dimensioning approach, the total tolerance between A and B is simply the sum of the upper and lower tolerances. Therefore, the total tolerance would be:

(0.015 + 0.005) = 0.02 inches

For the bilateral dimensioning approach, the total tolerance is calculated by taking the difference between the maximum and minimum dimensions. Therefore, the total tolerance would be:

(2.005 - 1.985) = 0.02 inches

For the limit dimensioning approach, the total tolerance is the difference between the maximum and minimum limits. Therefore, the total tolerance would be:

(2.005 - 1.975) = 0.03 inches

In summary:

- Unilateral dimensioning approach: 0.02 inches
- Bilateral dimensioning approach: 0.02 inches
- Limit dimensioning approach: 0.03 inches

Note: Dimensioning is the process of specifying the dimensions, size, and location of features on a drawing. Tolerance refers to the allowable variation in a dimension and is usually specified as a plus/minus value or a range of values.

Consider the NACA 63-210 airfoil being tested in a low-speed wind tunnel. The tunnel test section measures 3 ft tall and 4 ft wide. The airfoil has a 1.2-ft chord and stretches the 4-ft width of the tunnel test section.

Upstream of the test section, the air is at standard sea level conditions. In the test section, the velocity of the air is 80 ft/s. The airfoil has a drag coefficient of 0.009. At a point on the upper surface of the airfoil at the chordwise location with the maximum thickness, the pressure can be characterized as a lower value compared to the free-stream pressure, owing to the presence of the boundary layer.The upper surface of the airfoil experiences a reduced pressure due to the Bernoulli principle. The fluid speed is greater over the upper surface than it is over the lower surface of the airfoil, resulting in a reduced pressure in accordance with Bernoulli's equation.

Because of the viscosity of air, the pressure over the upper surface is less than it would be if the air was an inviscid fluid. This suggests that the air's viscosity has an impact on the pressures acting on the airfoil's surfaces, with a lower pressure being found on the upper surface compared to the free-stream pressure, owing to the presence of the boundary layer.

Answer: Therefore, the annual depreciation for each year using the double-declining-balance method is $228,000 for the first three years, $194,000 for the fourth year, and $0 for the fifth year. The book value at the end of each year is as follows: $422,000 at the end of year 1, $194,000 at the end of year 2, $228,000 at the end of year 3, $0 at the end of year 4, and $80,000 at the end of year 5.

Explanation:  To calculate the annual depreciation using the double-declining-balance method, we first need to calculate the depreciation rate, which is double the straight-line depreciation rate. The straight-line depreciation rate is calculated as follows:

Depreciation rate = (Cost - Salvage value) / Useful life

Depreciation rate = ($650,000 - $80,000) / 5 years = $114,000 per year

Double-declining-balance depreciation rate = 2 x straight-line depreciation rate = 2 x $114,000 = $228,000 per year

Using this depreciation rate, we can calculate the annual depreciation and book value at the end of each year as follows:

Year 1:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 = $422,000

Year 2:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $228,000 = $194,000

Year 3:

Depreciation = $194,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $194,000 = $228,000

Year 4:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $194,000 - $228,000 = $0

Year 5:

Depreciation = $0

Book value = Salvage value = $80,000
