Question

How much time is needed to produce 810 Joules of work if 90 watts of power is used?

Answer 1

Answer:

time = 0.1111111111 S. (seconds)

Explanation:

Power (watts) = work (joules) / time (seconds)

So: 90 = 810 / time

--Divide both sides by 810 to get time variable alone

90/810 = time

time = 0.1111111111 S. (seconds)

Hope this helps!
