A Carnot engine, used as refrigerator absorbs 380 J energy in one cycle from low temperature reservoir. If efficiency of this Carnot engine is 5% then amount of work done on refrigerator per cycle is

Find relation between efficiency (eta) of carnot engine and coefficient of performance (eta^( )) of refrigerator.

A Carnot heat engine has an efficiency of 10% . If the same engine is worked backward to obtain a refrigerator, then find its coefficient of performance.
