Question

If an engine can produce 670 J of energy in 1 min, how many watts can it output?

Answer 1

Answer:

11.2Watts

Explanation:

Given parameters:

Energy produced by the engine  = 670J

Time taken  = 1min  = 60s

Unknown:

Number of watts it can output  = ?

Solution:

This problem entails finding the power of the engine.

Power is the rate at which work is being done.

So;

      Power  = $\frac{Work done }{time}$  

       Power  = $\frac{670}{60}$    = 11.2Watts
