Letting x be east and y be north, find the components of v⃗ p/e (the velocity of the plane relative to the earth).

It indicates no change in temperature and the process of matter changing its state

Apossible long term health effects of stress would be work

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.
