2. Diagram 2 shows two objects of mass 75 kg and 90 kg respectively are separated by a distance, D. If the gravitational force between the two objects is 2.0 X 10^-7 " N and the value of gravitational constant, G = 6. 67 × 10^11 Nm^2 kg^-2 ? what is the value of D? ​

What color would an object that reflects green and blue light appear to be in white light? a. blue b. cyan c. magenta d. black

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.
