The print statement will execute a total of 4 times.

In the given code, there are two nested loops. The outer loop iterates over the range from 1 to 3, and the inner loop iterates over the range from 8 to 12 with a step of 2.

The outer loop runs twice, as it iterates from 1 to 2. For each iteration of the outer loop, the inner loop runs twice, as it iterates from 8 to 12 with a step of 2.

Therefore, the inner loop will execute a total of 2 times for each iteration of the outer loop. Since the outer loop runs twice, the inner loop will execute 2 times x 2 iterations = 4 times in total.

Hence, the correct answer is option a. 4.

The outer loop iterates from 1 to 2, so it runs twice. For each iteration of the outer loop, the inner loop iterates from 8 to 12 with a step of 2. This means the inner loop will run for values 8 and 10. Therefore, the inner loop executes 2 times for each iteration of the outer loop, resulting in a total of 4 executions of the print statement. The output of the print statement will be:

1. 8

2. 10

3. 8

4. 10

Hence, the correct answer is 4.

The answer to Question 37 is false. When there is a concentration of X-ray machines in one building, scatter radiation can become a problem. Scatter radiation is the radiation that is produced when the X-rays interact with matter in the body or in the surrounding environment. This can cause the X-rays to bounce off of objects and walls, creating secondary radiation that can be harmful to people who are not directly involved in the imaging process.

When there are multiple X-ray machines in a building, the amount of scatter radiation can increase significantly. This is because the X-rays from one machine can interact with the other machines, creating a cumulative effect. The more machines there are, the more radiation there is to scatter. This can be a particular problem in small buildings, where the radiation can accumulate quickly and create a hazardous environment for anyone who is in the building.

To reduce the risk of scatter radiation in a building with multiple X-ray machines, it is important to ensure that each machine is properly shielded and that there is adequate space between the machines. This can help to minimize the amount of scatter radiation that is produced and keep everyone in the building safe.

An automobile travels along a straight road at 15.65 m/s through a 11.18 m/s speed zone. A police car observed the automobile. At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile at a constant acceleration of 1.96 m/s2 . The motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s2

Find the total time required for the police car  to over take the automobile.

Answer:

15.02 sec

Explanation:

The total time required for the police car to overtake the automobile is related to the distance covered by both  cars which is equal from instant point of abreast.

So; we can say :

\(D_{pursuit} =D_{police}\)

By using the second equation of motion to find the distance S;

\(S= ut + \dfrac{1}{2}at^2\)

\(D_{pursuit} = (15.65 *12 )+(15.65 (t)+ (\dfrac{1}{2}*(-3.05)t^2)\)

\(D_{pursuit} = (187.8)+(15.65 \ t)-0.5*(3.05)t^2)\)

\(D_{pursuit} = (187.8+15.65 \ t-1.525 t^2)\)

\(D_{police} = ut _P + \dfrac{1}{2}at_p^2\)

where ;

u  = 0

\(D_{police} = \dfrac{1}{2}at_p^2\)

\(D_{police} = \dfrac{1}{2}*(1.96)*(t+12)^2\)

\(D_{police} = 0.98*(t+12)^2\)

\(D_{police} = 0.98*(t^2 + 144 + 24t)\)

\(D_{police} = 0.98t^2 + 141.12 + 23.52t\)

Recall that:

\(D_{pursuit} =D_{police}\)

\((187.8+15.65 \ t-1.525 t^2)= 0.98t^2 + 141.12 + 23.52t\)

\((187.8 - 141.12) + (15.65 \ t - 23.52t) -( 1.525 t^2 - 0.98t^2) = 0\)

= 46.68 - 7.85 t -2.505 t² = 0

Solving by using quadratic equation;

t = -6.16 OR  t = 3.02

Since we can only take consideration of the value with a  positive integer only; then t = 3.02 secs

From the question; The motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit;

Therefore ; the total time  required for the police car  to over take the automobile = 12 s + 3.02 s

Total time  required for the police car  to over take the automobile = 15.02 sec

The thevenin equivalent with respect to the terminals a and b is 0 V in series with 120 N.

Terminals are an interface between the user and a computer system. They allow users to interact with the system by providing a command line interface. Terminals are used to access applications and services, enter data, and produce output. They are also used to monitor system performance and manage system resources. Terminals can be either physical or virtual. Physical terminals use hardware, such as keyboards and monitors, to interact with the system.

To find the Thevenin equivalent with respect to the terminals a and b, we can use the Thevenin theorem.

This states that the Thevenin equivalent is equal to the open-circuit voltage (Vt) across the terminals a and b, in series with the equivalent resistance (Rt) between the terminals a and b.

Vt = 0 V

Rt = 120 N

Therefore, the Thevenin equivalent with respect to the terminals a and b is 0 V in series with 120 N.

  (c) 95.106 V

  (d) 25 V, 75 V

  (e) 23.776 V, 71.329 V

  (f) see attached

Explanation:

The peak value of the sine function is 1, so the peak value of U is ...

  100·1 = 100 V.

__

The argument of the sine function is 2πft, so f = 120πt/(2πt) = 60 Hz.

__

When t=0.020, the voltage is ...

  U = 100sin(120π·0.020) = 100 sin(2.4π) ≈ 95.106 V

__

The resistors are in the ratio of 1 : 3, so divide the source voltage in that ratio.

The peak voltage across the 5Ω resistor is 1/4 of 100 V, or 25 V.

The peak voltage across the 15Ω resistor is 3/4 of 100 V, or 75 V.

__

The same fractions as in (d) apply to the instantaneous voltage.

The voltage on the 5Ω resistor is 1/4·95.106 V ≈ 23.776 V

The voltage on the 15Ω resistor is 3/4·95.106 V ≈ 71.329 V

The egg-shaped surfaces machined onto a camshaft are called the Camshaft lobes.

As the camshaft rotates, lobes (referred to as cams) push against the valves to open them; the valves' springs close the valves back up. This is a crucial task that can significantly affect how well an engine performs at various speeds.

As long as the wear on the lobes is not extreme, camshafts can be rebuilt. Examples of a rebuildable and non-rebuildable camshaft are shown above.

Annealed copper

Given :

Width, b = 9 inches

Thickness, \($h_0=2.2$\) inches

K= 90,000 Psi

μ = 0.2, R = 14 inches, N = 150 rpm

For the maximum possible draft in one pass,

\($\Delta h = H_0-h_f=\mu^2R$\)

     \($=0.2^2 \times 14 = 0.56$\) inches

\($h_f = 2.2 - 0.56$\)

     = 1.64 inches

Roll strip contact length (L) = \($\sqrt{R(h_0-h_f)}$\)

                                             \($=\sqrt{14 \times 0.56}$\)

                                             = 2.8 inches

Absolute value of true strain, \($\epsilon_T$\)

\($\epsilon_T=\ln \left(\frac{2.2}{1.64}\right) = 0.2937$\)

Average true stress, \($\overline{\gamma}=\frac{K\sum_f}{1+n}= 31305.56$\) Psi

Roll force, \($L \times b \times \overline{\gamma} = 2.8 \times 9 \times 31305.56$\)

                                 = 788,900 lb

For SI units,

Power = \($\frac{2 \pi FLN}{60}$\)  

           \($=\frac{2 \pi 788900\times 2.8\times 150}{60\times 44.25\times 12}$\)

The electric power requirement, if the efficiency is 90% is given as 1667 W.

The heat loss due to radiation from the stove burner can be calculated using Stefan-Boltzmann Law: Q_rad = εσA(Ts^4 - T?^4),

where ε is the emissivity (1 for a blackbody), σ is the Stefan-Boltzmann constant \((5.67 x 10^-8 W/m^2K^4)\), A is the surface area \((\pi D^2/4)\), and Ts and T? are the absolute temperatures in Kelvin.

The heat loss due to convection is calculated using Newton's law of cooling: Q_conv = hA(Ts - T?), where h is the convection heat transfer coefficient.

The value of h depends on the nature of air flow (laminar or turbulent) and is typically 10-25 W/m^2K for natural convection.

The power requirement can be found by dividing the total heat loss by the efficiency of the energy transfer.

To calculate the heat loss by radiation, we first need to convert the temperatures to Kelvin: Ts = 250°C + 273.15 = 523.15 K, T? = 20°C + 273.15 = 293.15 K.

Then apply the Stefan-Boltzmann Law:

Q_rad = εσA\((Ts^4 - T?^4)\)

=\(1 * 5.67x10^-8 W/m^2K^4\)* \((\pi *(0.2 m)^2/4) * (523.15^4 - 293.15^4)\)

≈ 1354 W.

For heat loss by convection, without a specific heat transfer coefficient (h), If we assume h=10 W/m^2K,

Q_conv = hA(Ts - T?)

= 10 W/m^2K * (π*(0.2 m)^2/4) * (523.15 - 293.15)

≈ 146 W.

The electric power requirement, if the efficiency is 90%, is the total heat loss divided by the efficiency:

Power = (Q_rad + Q_conv) / 0.9

≈ (1354 W + 146 W) / 0.9

≈ 1667 W.
