Calculate the electrical force between two objects with charges of 2.2 uC and 4.2 uc. respectively, placed at different distances apart. Complete the table below with your
calculations. Graph the electrical force versus the distance between the two objects. Be sure to
include your axes labels and graph title. What happens to the force when the distance is
doubled? Quadrupled?

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.
