Consider a Carnot 's cycle operating between `T_1 = 500 K` and `T_2 = 300 K`producing 1 kJ of mechanical work per cycle. Find the heat transferred to the enginer by the reservoirs.

A Carnot engine working between 300 Kand 400 K has 800 J of useful work. The amount of heat energy supplied to the engine from the source is

A Carnot engine working between 200 Kand 500 K has done work equal to 800 joules. Amount of heat energy supplied to the engine from the source is

The efficiency of a Carnot engine which operates between the two temperatures T_1=500K and T_2=300K is

Distinguish between G_1 , S and G_2 Phase of cell cycle.

In a heat engine , the temperature of the source and sink are 500 K and 375 K . If the engine consumes 25 xx 10^5 J per cycle, find heat rejected to the sink per cycle.

In a heat engine , the temperature of the source and sink are 500 K and 375 K . If the engine consumes 25 xx 10^5 J per cycle, find the efficiency of the engine.

An ideal heat engine working between temperature T_(1) and T_(2) has an efficiency eta , the new efficiency if both the source and sink temperature are doubled, will be

Two vibrating tuning forks produce prograssive waves given by y_1 = 4sin 500 pi t , and y_2 =2 sin 506 pi t and are hold near the ear of a person Number of beats head per minute is

Two Carnot engines A and B are operated in series. A receives heat at 900 K and rejects it to the reservoir at TK. B receives the rejected heat from Aand rejectsit to itsreservoir at 400 K. If the work outputs of A and B are equal, then T is

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
