A river does 6500 J of work on a water wheel every second. The wheels efficiency is 12%
A. How much worked in joules can the axle of the wheel do?
B. What is the power output of the wheel in 1s?

Answer :

The power output is 6500 J - ( 12% of 6500 J)

= 5460 J .

Is the first question complete? Because the work done by the river would be equal to work done by the axle of the wheel.
