If Jim is pushing a chair with 12N of force to the right while John is pushing with a force of 24N to the Left, what is the net force acting on the chair? A 0 N

B 12 N to the Right

C 24 N to the Right

D 12 N to the left

HURR

Ibelieve that the correct answer is: c. along plate boundaries

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.

What the heck r u talkin bout? ?
