Two carnot engines are connected to each other. The second engine uses the heat flow out of the first engine as its energy input. The first engine operates between T1 and T2 (T1>T2) and the second engine operates between T2 and T3 (T2>T3). a) Find the efficiency of the combined system of the two engines. b) For the work done by the engines to be equal to each other, what should be T2? c) If the engines have the same efficiency, what is T2?
