Determine the rate at which the electric field changes between the round plates of a capacitor, 5.6 cmcm in diameter, if the plates are spaced 1.4 apart and the voltage across them is changing at a rate of 140 V/sV/s .

Since the pully is a simple machine so the mechanical advantage is a 1

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.

True will be your answer dude

The answer is -6hope this
