The forklift exerts a 1,500.0 n force on the box and moves it 3.00 m forward to the stack. how much work does the forklift do against the force of gravity?

a) 1.50 × 10^3 j

b) 0.00 j

c) 500 j

d) 4.50 × 10^3 j

i think it is d, but i can also justify b, !

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.
