What percentage `T_(1)` is of `T_(2)` for a `10%` efficiency of a heat engine?

What per cent T_(1) is of T_(2) for a heat engine whose efficiency is 10%

Can the efficiency of heat engine be 100% ? Justify

The efficiency of a carnot heat engine is 0.6 when the absolute temperatures of the source and sink are T_(1) and T_(2) respectively. The efficiency of another carnot engine is also 0.6 but the source and sink temperatures are different. What are the temperatures of the source and the sink of the other engine ?

What is a heat engine? Explain the efficiency of a heat engine.

The efficiency of carnot's heat engine is 0.5 when the temperature of the source is T_(1) and that of sink is T_(2) .The efficiency of another crot's heat engine is also 0.5.the temperature of source and sink of the second engine are respecitvely

Two Carnot engines A and B are operated in series. The engine A receives heat from the source at temperature T_1 and rejects the heat to the sink at temperature T. The second engine B receives the heat at temperature T and rejects to its sink at temperature T_(2) . For what value of T the efficiencies of the two engines are equal?

Two Carnot engines A and B are operated in series. The engine A receives heat from the source at temperature T_1 and rejects the heat to the sink at temperature T. The second engine B receives the heat at temperature T and rejects to its sink at temperature T_(2) . For what value of T the efficiencies of the two engines are equal?
