identical spheres are dropped from a height of 100m above the surfaces of both planet x and planet y. the position of the spheres as a function of time is recorded as the spheres fall. these data are shown in the graphs above. which planet exerts a greater gravitational force on the sphere, and what evidence supports this conclusion?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

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.
