Answer 1

Answer:

Explanation:

Power is the rate work is done, so this would involve how long it would take to do a certain amount of Work and it is also the measure of the transfer of energy over a period of time.

The formula for power is:

$P = \dfrac{W}{t}$

Where:

P = Power

W = Work

t = time
