When electric power is transferred over a long distance then, line loss can be reduced by high voltage and low current. Thus, option A is correct.

The complete question is attached to the image below.

The electric circuit transfers the electric current then it is called electric power. The loss in the line over a larger distance is reduced by transferring AC instead of DC voltage.

The AC transmitted is of high voltage, and the power is low. The equation for current is given,

P = VI

The increase in the voltage causes the decrease in the current and in turn the resistance also reduces resulting in the loss of the power of the circuit to decrease.

Therefore, the loss is reduced by transferring high voltage and, low current AC.

When reconnecting the two-winding transformer as an autotransformer, we need to connect the windings in series. The resulting voltage will be the sum of the two windings, which is 120+90=210 V. Since we want to supply a load at 120 V, we need to tap the autotransformer at a point where the voltage is 120 V. This means that the voltage ratio is 210/120=1.75.

Since we are assuming an ideal transformer, the power is conserved, which means that the kVA rating of the transformer remains the same. Therefore, the maximum load that can be supplied without exceeding the current rating of the windings is 27 kVA.

The efficiency of the transformer can be calculated as follows:

Efficiency = (Output Power) / (Input Power)

The output power is the kVA loading at 0.85 power factor, which is 27*0.85=22.95 kVA.

The input power can be calculated as the sum of the core loss and copper loss:

Input Power = Core Loss + Copper Loss + Output Power

Input Power = 250 W + 840 W + 22.95 kVA = 22.95+0.29 = 23.24 kVA

Therefore, the efficiency is:

Efficiency = 22.95 kVA / 23.24 kVA = 0.988 or 98.8% (rounded to the nearest tenth)

Answer:

The volume percent of graphite is 91.906 per cent.

Explanation:

The volume percent of graphite (\(\% V_{Gr}\)) is determined by the following expression:

\(\%V_{Gr} = \frac{V_{Gr}}{V_{Gr}+V_{Fe}} \times 100\,\%\)

\(\%V_{Gr} = \frac{1}{1+\frac{V_{Gr}}{V_{Fe}} }\times 100\,\%\)

Where:

\(V_{Gr}\) - Volume occupied by the graphite phase, measured in cubic centimeters.

\(V_{Fe}\) - Volume occupied by the ferrite phase, measured in cubic centimeters.

The volume of each phase can be calculated in terms of its density and mass. That is:

\(V_{Gr} = \frac{m_{Gr}}{\rho_{Gr}}\)

\(V_{Fe} = \frac{m_{Fe}}{\rho_{Fe}}\)

Where:

\(m_{Gr}\), \(m_{Fe}\) - Masses of the graphite and ferrite phases, measured in grams.

\(\rho_{Gr}\), \(\rho_{Fe}\) - Densities of the graphite and ferrite phases, measured in grams per cubic centimeter.

Let substitute each volume in the definition of the volume percent of graphite:

\(\%V_{Gr} = \frac{1}{1 +\frac{\frac{m_{Gr}}{\rho_{Gr}} }{\frac{m_{Fe}}{\rho_{Fe}} } } \times 100\,\%\)

\(\%V_{Gr} = \frac{1}{1+\left(\frac{m_{Gr}}{m_{Fe}} \right)\cdot \left(\frac{\rho_{Fe}}{\rho_{Gr}} \right)}\times 100\,\%\)

Let suppose that 100 grams of cast iron are available, masses of each phase are now determined:

\(m_{Gr} = \frac{2.5}{100}\times (100\,g)\)

\(m_{Gr} = 2.5\,g\)

\(m_{Fe} = 100\,g - 2.5\,g\)

\(m_{Fe} = 97.5\,g\)

If \(m_{Gr} = 2.5\,g\), \(m_{Fe} = 97.5\,g\), \(\rho_{Fe} = 7.9\,\frac{g}{cm^{3}}\) and \(\rho_{Gr} = 2.3\,\frac{g}{cm^{3}}\), the volume percent of graphite is:

\(\%V_{Gr} = \frac{1}{1+\left(\frac{2.5\,gr}{97.5\,gr} \right)\cdot \left(\frac{7.9\,\frac{g}{cm^{3}} }{2.3\,\frac{g}{cm^{3}} } \right)} \times 100\,\%\)

\(\% V_{Gr} = 91.906\,\%\)

The volume percent of graphite is 91.906 per cent.

Refrigerants from a refrigeration system that has a burned out motor-compressor assembly can be dangerous because it could contain a high concentration of toxic chemicals such as chlorine, fluorine, or bromine. These chemicals can pose a significant danger to the environment and human health, especially if they are released into the atmosphere.

In a refrigeration system, the refrigerant is responsible for absorbing heat from the inside of the unit and releasing it outside. This process is repeated continuously to maintain the desired temperature. The compressor is the heart of the refrigeration system, and it compresses the refrigerant gas to increase its temperature and pressure so that it can release the heat it has absorbed. If the motor-compressor assembly burns out, the refrigerant may not be circulated properly, which can cause it to stagnate and decompose.

These chemicals can be harmful to people and the environment if they are released into the atmosphere.To avoid these hazards, it is essential to handle refrigerants carefully, especially when repairing or disposing of refrigeration units. Technicians who handle refrigerants must be trained and certified to ensure that they know how to handle these chemicals safely. They must follow proper procedures for handling and disposing of refrigerants to prevent environmental contamination and protect human health.

In summary, the refrigerants from a refrigeration system that has a burned out motor-compressor assembly can be dangerous because it could contain a high concentration of toxic chemicals such as chlorine, fluorine, or bromine, and it is important to handle these chemicals carefully to avoid environmental contamination and protect human health.

To implement a Java method sumArray that returns the sum of the values in a given double array, you can write the following code.

This method takes in a double array as its parameter and initializes a variable called "sum" to zero. It then iterates through the array using a for loop, adding each value in the array to the sum. Finally, it returns the total sum of the values in the array. The sumArray method starts by creating a variable called "sum" and setting it equal to zero. This variable will be used to keep track of the total sum of the array values. For each index in the array, the method adds the value at that index to the "sum" variable using the += operator. This will accumulate the sum of all the values in the array.

```java
public static double sumArray(double[] a) {
   double sum = 0;
   for (int i = 0; i < a.length; i++) {
       sum += a[i];

The loop-current method is a widely used method in circuit analysis to determine the loop currents in a circuit.

This method involves the use of Kirchhoff's current law to write equations for each loop in a circuit. The current law states that the sum of the currents entering a node is equal to the sum of the currents leaving the node. Using this method, we can write a set of equations for each loop in the circuit. For example, for a circuit with three loops, we would write three equations, one for each loop. These equations would relate the loop currents to the sources and the resistors in the circuit. To simplify the equations, we would use Ohm's law to express the currents in terms of the voltages and resistances in the circuit. We would then substitute the known values for the sources and the resistors into the equations to obtain a set of three equations in terms of the loop currents.
