Calculate the gravitational acceleration of an object with mass of 50 kg above the surface of the Earth. Given that the mass of the Earth is 5.97 x 1024 kg and the radius of the Earth is 6.37
x 106 m.

Fitness is the ability to perform only very light levels of physical activity.

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.
