Use the information below for the two (2) following questions: An ideal heat engine uses 0.01 mole of gas and operates between a hot reservoir at TH = 400 K and cold reservoir at TL = 300 K, in a cycle from a -> b -> c -> d -> a. From a -> b the gas undergoes an isothermal expansion, changing its volume from Va to 2.5Va. From b -> c, the pressure is reduced at a constant volume. From c -> d, the gas undergoes an isothermal compression, and from d -> a, the pressure is increased at a constant volume until the gas is back at the original condition at a. If the engine operates at 50 cycles per second, the power output is
