Explanation:

Conductivity and ductility are properties of metals that determine their ability to conduct electricity and be molded into different shapes, respectively.

Conductivity refers to a metal's ability to conduct electricity. Metals are known for their high conductivity, meaning they allow electricity to flow through them easily. This property is due to the fact that metals have free electrons in their outer shell, which are free to move and carry an electrical charge. The conductivity of a metal can be affected by its temperature and impurities, as well as its atomic structure. Ductility, on the other hand, refers to a metal's ability to be stretched or drawn into a wire without breaking. This property is due to the way the atoms in a metal are arranged and the way they interact with each other. Ductile metals are malleable, meaning they can be bent, shaped, and molded without breaking. Metals with high ductility are ideal for shaping into wire, pipes, and other products that require flexibility and strength. In summary, conductivity and ductility are important properties of metals that determine their ability to conduct electricity and be shaped into various forms.

Answer:

Kelvin to Celsius: C = K - 273 (C = K - 273.15 if you want to

91% is the voltage applied to the load (secondary voltage) and the efficiency.

To determine the voltage applied to the load (secondary voltage) and the efficiency, we can use the equivalent circuit parameters of the transformer and the given load impedance.

Given parameters:

Transformer rating: 20 kVA

Transformer turns ratio: 800/230 [V]

R1 = R2 = 10 Ω

X1 = X2 = 50 Ω

Rc = 100 Ω

Xm = 20 kΩ

Load impedance: ZL = 2+j0.6 Ω

First, we can calculate the equivalent impedance seen by the primary side of the transformer using the turns ratio:

Zeq = (ZL * (N2/N1)^2) = (2+j0.6 * (230/800)^2) = 0.79+j0.237 Ω

Next, we can calculate the primary current (I1) using the formula:

I1 = V1 / (R1 + jX1 + Zeq) = 800 / (10+j50 + 0.79+j0.237) = 8.29 - j2.35 A

Now, we can calculate the secondary voltage (V2) using the turns ratio:

V2 = V1 * (N2/N1) = 800 * (230/800) = 230 V

Finally, we can calculate the efficiency (η) using the formula:

η = (Pout / Pin) * 100

Where Pout is the output power and Pin is the input power. Since this is a single-phase transformer, the power factor is given by:

Power Factor (PF) = Pout / Pin = (V2 * I2) / (V1 * I1)

We know V2 = 230 V, V1 = 800 V, and we can calculate I2 using Ohm's Law:

I2 = V2 / ZL = 230 / (2+j0.6) = 105.56 + j31.67 A

Now, we can calculate the power factor:

PF = (V2 * I2) / (V1 * I1) = (230 * (105.56 + j31.67)) / (800 * (8.29 - j2.35))

= 0.91 + j0.21

Finally, we can calculate the efficiency:

η = (PF) * 100 = (0.91 + j0.21) * 100 = 91% + j21%

Therefore, the secondary voltage applied to the load is 230 V, and the efficiency of the transformer is 91% with a power factor of 0.91 leading.

Explanation:

srry if wrong

A standing wave has points of constructive interference called antinodes and points of destructive interference called nodes

This position, where the resulting wave is larger than either of the two original, is called constructive interference.

When the first wave is leading, the second wave is down and the addition of the two is zero. This is called destructive interference.

A standing wave occurs when two waves with the same properties moving in the opposite direction, in the same media, interfere with one another.

Nodes are points where the waves interact destructively, causing an appearance of the wave standing still.  The opposite of nodes is antinodes where they are points of maximum displacement due to constructive destruction.

Thus the standing wave has points of constructive interference called antinodes and points of destructive interference called nodes

Explanation:

Using the equation of motion formula

∆S = ut+1/2at²

S2-S1 = ut+1/2gt²

u is the initial velocity

t is the time taken = 2secs

g is the acceleration due to gravity = 9.81m/s²

30-S1= 0(2)+1/2(9.81)2²

30- S1 = 0+4.905(4)

30 -S1 = 19.62

-S1 = 19.62-30

It can be said that the car which travels first at 40 miles in 40 minutes and then 30 miles in 30 minutes is traveling at a constant speed.

The formula and procedure we will use to solve this exercise is:

v = x /t

Where:

Information about the problem:

Applying the velocity formula for the first data information of the travel, we get:

v₁ = x₁ /t₁

v₁ = 40 miles /40 min

v₁ = 1 mile/min

Applying the velocity formula for the second data information of the travel, we get:

v₂ = x₂ /t₂

v₂ = 30 miles /30 min

v₂ = 1 mile/min

As we notice v₁ = v₂ that means that the car is traveling with a constant speed during the trip

The electrostatic force between two point charges is given by Coulomb's law: F = (1/4πε₀) ((q1 q2)/r²). The work done by the electrostatic force on the moving point charge is -0.332 J.

The electrostatic force between two point charges is given by Coulomb's law:

F = (1/4πε₀) ((q1 q2)/r²)

where ε₀ is the permittivity of free space, q1 and q2 are the charges of the particles, and r is the distance between them.

The work done by a force over a displacement is given by:

W = F * d * cos(theta)

where d is the displacement and theta is the angle between the force and the displacement.

In this problem, the electrostatic force and displacement are in the same direction, so theta = 0 and the cosine term is 1. Therefore, we only need to calculate the force and displacement.

The distance between the two point charges is:

r = sqrt((0.245 - 0.110)² + (0.285 - 0)²) = 0.245 m

The force on q2 due to q1 is:

F = (1/4πε₀) ((q1 q2)/r²) = (9.0×10^9 N·m²/C²) ((3.20×10^-6 C)(-4.20×10^-6 C)/(0.245 m)²) = -1.095 N

The negative sign indicates that the force is in the opposite direction to the displacement.

The displacement is:

d = sqrt((0.245 - 0.110)² + (0.285 - 0)²) = 0.303 m

The work done by the electrostatic force on q2 is:

W = F * d = (-1.095 N) (0.303 m) = -0.332 J

Therefore, the work done by the electrostatic force on the moving point charge is -0.332 J.

Newton's third law of motion states that for every action, there is an equal and opposite reaction. The action-reaction pair is used to describe the interaction between two objects. Therefore, when a car is speeding up as it drives along a level road, an action-reaction pair occurs.

An action-reaction pair is a pair of forces that are equal in strength and opposite in direction. When an object exerts a force on another object, the second object exerts an equal and opposite force on the first object. The action-reaction pair when a car speeds up as it drives along a level road can be explained as follows: Action force: The car exerts a force on the road in the forward direction. This is the action force. Reaction force: The road exerts a force on the car in the backward direction. This is the reaction force.

To understand the concept of moment of a force and how to calculate it using a scalar formulation. The magnitude of the moment of a force with a magnitude f around a point o is defined as follows:

The moment of a force, also known as torque, is a measure of the rotational effect of the force around a particular point. It depends on both the magnitude of the force and the distance from the point of rotation. The formula to calculate the moment of a force is given by: Mo = f * d, where Mo is the moment of the force, f is the magnitude of the force, and d is the perpendicular distance between the point of rotation and the line of action of the force.

The moment of a force is a vector quantity, but it can also be represented by a scalar value. To calculate the scalar moment, we only consider the magnitude of the force and the perpendicular distance. By multiplying these two values, we get the scalar moment. It is important to note that the direction of the moment is determined by the right-hand rule.
In summary, the moment of a force is a measure of the rotational effect and can be calculated using the scalar formulation Mo = f * d, where f is the magnitude of the force and d is the perpendicular distance from the point of rotation.

The producer of refrigerator compressors needs to determine the number of kanbans required for implementing a just-in-time production line to meet the demand for 150 compressors per day from a neighboring appliance manufacturer.

To calculate the number of kanbans required, we need to consider the production lead time, safety stock factor, and optimal production quantity. The production lead time is 5 days, which means that it takes 5 days to produce a batch of compressors once the production process starts.

The safety stock factor is 17%, indicating that the producer wants to maintain an additional 17% of the daily demand as safety stock to mitigate any unforeseen fluctuations. The optimal production quantity is 95 units, which is the batch size that minimizes setup costs.

To determine the number of kanbans, we first need to calculate the total demand during the production lead time. Since the demand is 150 compressors per day and the lead time is 5 days, the total demand during the lead time is 150 compressors/day * 5 days = 750 compressors. Adding the safety stock, the total demand becomes 750 compressors + (17% * 150 compressors) = 750 compressors + 25.5 compressors = 775.5 compressors.

Next, we divide the total demand by the optimal production quantity to get the number of kanbans required. The number of kanbans is calculated as 775.5 compressors / 95 compressors per kanban = 8.16 kanbans. Since we cannot have a fraction of a kanban, we round up to the nearest whole number. Therefore, the producer of compressors requires 9 kanbans to meet the demand of 150 compressors per day from the neighboring appliance manufacturer.
