A point charge with charge q1 = 3.90 μC is held stationary at the origin. A second point charge with charge q2 = -4.20 μC moves from the point ( 0.120 m , 0) to the point ( 0.275 m , 0.245 m ). How much work W is done by the electric force on the moving point charge?

Global warming was a major concern some people do not care global warming is fake it is not real the percentage of it happening  is slight 

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.

Ive never heard of creep meters
