Technician B is correct.A fuse is a component of an electrical circuit that acts as a safety mechanism in the event of an overload or a short circuit. A circuit overload happens when too much current passes through the circuit, causing the wires to heat up and potentially causing a fire.

A short circuit happens when a live wire comes into contact with a neutral wire or the earth, resulting in a large flow of current.A fuse is a small component that is inserted into an electrical circuit to protect it from short circuits and overloads. When a fuse is exposed to a large flow of current, it heats up and melts, preventing the current from flowing any further. When this occurs, the fuse is said to have blown.The two technicians are discussing fuse testing. Technician A believes that if the fuse is okay, a test light should illuminate on both test points of the fuse. Technician B believes that if a test light only illuminates on one side of the fuse, the fuse is defective. Technician B is correct.A test light can be used to check if a fuse is blown or not. When a test light is placed on the test points of a fuse, if the fuse is good, the light will illuminate on both sides. If only one side of the fuse illuminates, it means that the fuse has blown and needs to be replaced. Hence, technician B is correct.

To create a program that implements a function partition () to print a list of soccer players, you can use the following Python code:```
def partition(input_string):
   soccer_players = input_string.split(",")
   print("Soccer Players:")
   for player in soccer_players:
       print(player)
input_string = input("Enter the names of soccer players separated by comma: ")
partition(input_string)
```The above program prompts the user to input a string of soccer player names separated by a comma. The `partition()` function splits the input string by comma and stores the resulting names in a list called `soccer_players`.It then prints out the string "Soccer Players:" followed by each player's name in the list using a for loop that iterates over the `soccer_players` list. The `partition()` function takes a string of first names separated by commas as input and prints the names of those soccer players.

Answer:

L = 75.25 mm

Explanation:

First we need to find the lateral strain:

Lateral Strain = Change in Diameter/Original Diameter

Lateral Strain = (20.025 mm - 20 mm)/20 mm

Lateral Strain = 1.25 x 10⁻³

Now, we will find the Poisson's Ratio:

Poisson's Ratio = (E/2G) - 1

where,

E = Elastic Modulus = 105 GPa

G = Shear Modulus = 39.7 GPa

Therefore,

Poisson's Ratio = [(105 GPa)/(2)(39.7 GPa)] - 1

Poisson's Ratio = 0.322

Now, we find longitudinal strain by following formula:

Poisson's Ratio = - Lateral Strain/Longitudinal Strain

Longitudinal Strain = - Lateral Strain/Poisson's Ratio

Longitudinal Strain = - (1.25 x 10⁻³)/0.322

Longitudinal Strain = - 3.87 x 10⁻³

Now, we can fin the original length:

Longitudinal Strain = Change in Length/L

where,

L = Original Length = ?

Therefore,

- 3.87 x 10⁻³ = (74.96 mm - L)/L

(- 3.87 x 10⁻³)(L) + L = 74.96 mm

0.99612 L = 74.96 mm

L = 74.96 mm/0.99612

L = 75.25 mm

Complete Question:

If both the ram air input and drain hole of the pitot system become blocked, the indicated airspeed will

a) increase during a climb

b) decrease during a climb

c) remain constant regardless of altitude change

Answer:

0.5 kW

Explanation:

The given parameters are;

Volume of tank = 1 m³

Pressure of air entering tank = 1 bar

Temperature of air = 27°C = 300.15 K

Temperature after heating  = 477 °C = 750.15 K

V₂ = 1 m³

P₁V₁/T₁ = P₂V₂/T₂

P₁ = P₂

V₁ = T₁×V₂/T₂ = 300.15 * 1 /750.15 = 0.4 m³

\(dQ = m \times c_p \times (T_2 -T_1)\)

For ideal gas, \(c_p\) = 5/2×R = 5/2*0.287 = 0.7175 kJ

PV = NKT

N = PV/(KT) = 100000×1/(750.15×1.38×10⁻²³)

N = 9.66×10²⁴

Number of moles of air = 9.66×10²⁴/(6.02×10²³) = 16.05 moles

The average mass of one mole of air = 28.8 g

Therefore, the total mass = 28.8*16.05 = 462.135 g = 0.46 kg

∴ dQ = 0.46*0.7175*(750.15 - 300.15) = 149.211 kJ

The power input required = The rate of heat transfer = 149.211/(60*5)

The power input required = 0.49737 kW ≈ 0.5 kW.

A compressor that compresses gas between a fixed spiral and an orbiting spiral is called a scroll compressor.

A scroll compressor is a type of positive displacement compressor commonly used for compressing gases. It consists of two main components: a fixed spiral and an orbiting spiral. The fixed spiral remains stationary, while the orbiting spiral moves in an eccentric motion. The gas is trapped between the two spirals and is progressively compressed as the orbiting spiral moves closer to the fixed spiral. This action creates a series of crescent-shaped gas pockets that decrease in size, resulting in the compression of the gas.

Scroll compressors are known for their smooth operation, low noise levels, and high efficiency. They are widely used in various applications, including air conditioning, refrigeration, and gas compression. The design of the scroll compressor provides a continuous flow of compressed gas with minimal pulsations, making it a reliable and efficient choice for many industrial and commercial applications.

The motor must supply a torque of 0.1676 Nm to take the plastic disk from 0 to 2000 rpm in 5.0 s.

The torque that the motor must supply to take the plastic disk from 0 to 2000 rpm in 5.0 s can be calculated using the formula:
torque = (moment of inertia x angular acceleration) / radius


The moment of inertia of the plastic disk can be calculated using the formula:

moment of inertia = (1/2) x mass x radius^2

Substituting the given values, we get:

moment of inertia = (1/2) x 0.2 kg x (0.1 m)^2 = 0.001 kg m^2

The angular acceleration can be calculated using the formula:

angular acceleration = (final angular velocity - initial angular velocity) / time

Substituting the given values, we get:

angular acceleration = (2π x 2000 rpm - 0 rpm) / (60 s/min x 5.0 s) = 83.78 rad/s^2

Finally, substituting the values for moment of inertia, angular acceleration, and radius into the torque formula, we get:

torque = (0.001 kg m^2 x 83.78 rad/s^2) / 0.05 m = 0.1676 Nm
