Two Carnot engines are operated in succession. The first engine receives heat from a source at `T=800K` and rejects to sink at `T_(2)K`. The second engine receives heat rejected by the first engine and rejects to another sink at `T_(3)= 300K`. If work outputs of the two engines are equal, then find the value of `T_(2)`.

Two Carnot engines A and B are operated in succession. The first one , A receives heat from a source at T_1 = 800 K and rejects to sink at T_2K . The second engine B receives heat rejected by the first engine and rejects to another sink at T_3 = 300K . If the work outputs of two engines are equal , them the value of T_2 is

Two Carnot engines A and B are operated is succession. The first one A receives heat from a source at T_(1)=800K and rejects to a sink at T_(2)K . The second engine B receives hence rejected by the first engine and rejects the another sink at T_(3) =300K. If the efficiencies of two engines are equal, then the value of T_(2) is

Two carnot engines A and B are operated in series. The first one A receives heat at 900K and rejects it to a reservoir at T K . The second engine B receives the heat rejected by the first engine and rejects it to a heat reservoir at 400K . Calculate the value of T , when the efficiency of two engines is the same.

Two Camot engines A and B are operated in series. The first one, A , receives heat at T_(1)(=600 K) and rejects to a reservoir at temperature T_(2) . The second engine B receives heat rejected by the first engine and, in turn, rejects to a heat reservoir at T_(3)(=400K). Calculate the temperature T_(2) if the work outputs of the two engines are equal :
