How much power can a motor output if it does 25 J of work in 1 s? *

Because the dept in the ocean

there are no components of a physical goal mentioned on the list of choices that you've provided.

The power is 25 W

Explanation:

Given;

work done by motor output. E = 25 J

Time taken to complete this task, t = 1 s

Power is the amount of work done per unit time or energy per unit time.

The amount of power developed by the motor, can be calculated as follows using the formula below;

[tex]Power = \frac{Energy}{time} = \frac{25}{1} = 25 \ W[/tex]

Therefore, the amount of power developed by the motor in the given time is 25 W.

25 W

Explanation:

Power: This can be defined as the rate at which work is done. The S.I unit of power is Watt (W).

The expression of power is given as

Power = work output/time

P = W/t Equation 1

Given: W = 25 J. t = 1s

Substitute into equation 1

P = 25/1

P = 25 W

Hence the output power of the motor is 25 W
