Part a
A heat engine absorbs 1200 J of heat from a high-temperature reservoir and rejects 900 J to a low-temperature reservoir in each cycle. Calculate the net work done per cycle by the engine.
Part b
If the engine operates at a frequency of \(f\) cycles per second (Hz), calculate its average power output in terms of \(f\).
Part b
The piston assembly has a mass of 15 kg. It accelerates outwards at \(4.0 \text{ m s}^{-2}\). Determine the net force acting on the piston. Hence, deduce the magnitude of the total opposing force acting on the piston.
