Acar uses 2500 joules in 25 seconds. find power

100 W

Explanation:

The power can be defined as energy change / time taken

Or

Energy used/time taken

So in this case you get,

Power = 2500/25 = 100 W

power = 100 watts

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
