Our friend peter back at the zoo is using a crane to lift an elephant into an enclosure. the elephant weighs 10,000 n. the crane lifts the elephant 5 meters in 25 seconds. how much power was used to accomplish this task?

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade

Ithink it’s 98 because jajajjajansmsmjs

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.

The geological theory that states that pieces of earth's lithosphere are in constant slow motion is the theory of plate tectonics.
