Question

A steam engine does 12 kJ or work in 55 s. how much power does the engine produce?

Answer 1

p=w/t
12kj=12000J
the answer is p=12000/55=218.18

Answer 2

Power, P = 218.18 watts

Step-by-step explanation:

It is given that,

Work done by the steam engine,
`W=12\ kJ=12* 10^3\ J`

Time taken to do work, t = 55 seconds

Power produced by the engine is given by work done divided by time taken i.e.

`P=(W)/(t)`

`P=(12* 10^3\ J)/(55\ s)`

P = 218.18 watts

Hence, this is the required solution.
