How many horsepower are required to compress 20 lbmol⁄hr of helium = 1.666) from 1 atm at 68°f to 10 atm using (a) a single adiabatic compressor? (b) a two-stage, adiabatic compressor with optimum inter-stage pressure and inter-stage cooling to 68°f? (see textbook for example.)

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
