When sugar is poured from the bag into the sugar bowl, the rubbing of the sugar grains creates a static electric charge that repels the grains and causes sugar to go flying out in all directions. If two sugar grains each acquire a charge of 7.10×10-11 C at a separation of 322 micrometers, with what force will they repel each other?

The answer to your is is c motion and shape

Cin carbonh in hydrogeno in oxygen

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.
