Question

Calculate the rate of energy flow or power for a battery that generates close to 5000J over the course of 180 seconds. Which formula should be used for this calculation?

A) Power = Energy / Time
B) Power = Time / Energy
C) Power = Energy x Time
D) Power = Energy - Time

Answer 1

The formula to calculate the rate of energy flow or power is Power = Energy / Time. Plugging in the values into the formula, the rate of energy flow or power for the battery is approximately 27.78W.

Step-by-step explanation:

The formula to calculate the rate of energy flow or power is:

Power = Energy / Time

In this case, the energy generated by the battery is close to 5000J and it takes 180 seconds. Plugging in the values into the formula:

Power = 5000J / 180s

Therefore, the rate of energy flow or power for the battery is approximately 27.78W.
