Two spheres are touching. Sphere A has a mass of 3.2 slug and a diameter of 15 inch, while Sphere B has a mass of 4.5 slug and a diameter of 18 inch. Determine the
gravitational force Sphere A applies to Sphere B.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
