Answer:

power = 100 watts

Step-by-step explanation:

Power is said to be the rate at which work is done. Power is the work done or energy used per unit time. Mathematically, it can be defined as the work done per unit time.

Power = work/time

Power = w/t

Work done is measured in joules and time is measured in seconds.

Power is measured in joules per seconds or watts.

power = w/t

w = 2500 joules

t = 25 seconds

power = 2500/25

power = 100 watts

Or
