A ball moving at 8.4 m/s rolls off of the edge of a cabinet and lands 5.2 m from the base of the cabinet.
How high is the edge of the cabinet?

t=d/v
d=1/2at^2

Amagnetic field "does not" interact with stationary electric charges. so, a.hope my answer you : )

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.
