Consider a person sliding down a water slide at constant velocity. What are the forces acting on the person as they slide? Determine if the forces are balanced or unbalanced. Explain.

Which principle states: "geologic processes taking place on earth today operated similarly in the past and can be used to explain past geologic events"? a. lateral continuity

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.
