A student wants to use a ramp to move boxes into a truck bed that is 3 m high. He has a choice of 2 different ramps. The length of one ramp is 2m, and the length of the other ramp is 8m. Which one will make his work easier? A. 8m, because he has to apply more force over a greater distance. B. 8m, because he has to apply less force over a greater distance. C. 2m, because he has to apply less force over a greater distance. D. 2m, because he has to apply more force over a greater distance

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
