Damon Powell · Answer 1

20000 W

Explanation:

Power: This can be defined as the rate at which energy is dissipated or used. The S. I unit of power is Watt (W).

The expression of power is given as,

P = E/t ... Equation 1

Where P = power, E = Energy, t = time.

Given: E = 200 J, t = 0.01 s

Substitute into equation 1

P = 200/0.01

P = 20000 W.

Hence the average power = 20000 W
