The pilot of an airplane notes that the compass indicates a heading due west. the airplane's speed relative to the air is 130 km/h. the air is moving in a wind at 35.0 km/h toward the north. find the velocity of the airplane relative to the ground.

Answerboth technicians (a) and (b);

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.
