A Carnot engine is operated between two heat reservoirs at temperatures of 520 K and 300 K. If the engine receives 6.45 kJ of heat energy from the reservoir at 520 K in each cycle, how many joules per cycle does it reject to the reservoir at 300 K? How much mechanical work is performed by the engine during each cycle?
