Asked by John Desmond
An engine has an efficiency of 60%. If the heat source inputs
26,000 J of heat energy every second, show why the engine
does 15,600 J of work every second.
I really have no clue how to do this question.

the energy in is 26,000 Joules/second
the energy(work) out is x Joules per second
energy out per second = efficiency * energy in per second
x = 0.60 * 26,000
x = 15,600 Joules per second (which is Watts by the way)
