Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at 0.14 mpa, and leaves as superheated vapor at 0.8 mpa and 60°c at a rate of 0.06 kg/s. determine the rates of energy transfers by mass into and out of the compressor. assume the kinetic and potential energies to be negligible.

The process in which the nucleus of an atom splits into two lighter atoms, releasing a large amount of energy is nuclear

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.
