If 68 W of power is produced in 18 seconds, how much work is done?
1 answer:
Answer: 1224 joules
Explanation:
Given variables are:
Power (p) = 68 W
Time taken (t) = 18 seconds
work done (w) = ?
Recall that power is the rate of work done per unit time i.e Power is obtained by dividing the work done by the time taken.
Hence, Power = work / time
Make work the subject formula
work = power x time
work = 68 watts x 18 seconds
work = 1224 joules
Thus, 1224 joules of work is done.
