The average amount of solar energy incident on the PV per day is 10000 kWh/day.

<h3>Equation</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let the PV array has an area equal to 50 square meters. Hence:

Average amount of solar energy incident on the PV per day = 200 kWh/m²/day * 50 m² = 10000 kWh/day.

Since temperature increases when the average kinetic energy of particles increases, what is happening to the added energy when t
Blizzard [7]

Latent heat is the heat required to change the phase. When the temperature remains constant during melting or boiling the added energy is employed in the phase change process.

<h3>What is average kinetic energy?</h3>

The average kinetic energy (KE) is defined as the one-half of the mass of each gas molecule times multiplied by the square of RMS velocity.

KE = \frac{1}{2}m (V_{rms})^{2}

where,

KE is the kinetic energy

m is the mass of each molecule

(V)rms is the RMS velocity

As we know since the temperature is increasing the average kinetic energy of the particle increases. So the added energy is utilized in the sensible heat due to which the temperature of the body increases resulting in the increase in average kinetic energy

But when the temperature remains constant during melting or boiling the added energy is converted into latent heat energy utilized to convert the phase of a substance.

A process generates 250 watts of useful energy and 600 watts of waste energy. WhT is the efficiency of the process?
Cloud [144]

The efficiency of the process is 42%

From the question given above, the following data were obtained:

Useful energy = 250 watt

Wasteful energy = 600 watt

<h3>Efficiency =? </h3>

The efficiency of the process can be obtained as illustrated below:

efficiency \:  =  \frac{useful \: energy}{wasteful \: energy}  \times 100 \\  \\ efficiency \:  =  \frac{250}{600}  \times 100 \\

<h3>Efficiency = 42%</h3>

Therefore, the efficiency of the process is 42%

If it takes 150 N of force to move a box. 10 meters, what is the work done on
Scrat [10]

Answer:

C ) 1500 Joules

Explanation:

In the attached image, we can see how the box was moved 10 meters by the force of 150 N.

The definition of work is W = F * d

therefore

W= 150*10 = 1500 J
