A 11 kg mass is pulled up with a 40 N and 50 N force, right with a 30 N and 4 points 35 N force, down with a 60 N and 20 N force, and left with a 50 N and a 20
N force. What is the acceleration of the mass?

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.

Does current flow through or across a resistor?
