A0.010 kg ball is shot from theplunger of a pinball machine.
because of a centripetal force of0.025 n, the ball follows a
circulararc whose radius is 0.29 m. what isthe speed of the
ball?

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.
