If a distant galaxy has a substantial redshift (as viewed from our galaxy), then anyone living in that galaxy would see a substantial redshift in a spectrum of the milky way galaxy. choose the correct explanation why the statement makes sense (or is clearly true) or does not make sense (or is clearly false).
a) this statement makes sense. the redshift means that we see the galaxy moving away from us, so observers in that galaxy must also see us moving away from them—which means they see us redshifted as well. b) this statement doesn't make sense. the redshift means that we see the galaxy moving to us, so observers in that galaxy must see us moving away from them—which means they don't see us redshifted. c) this statement makes sense. the redshift means that we see the galaxy moving to us, so observers in that galaxy must also see us moving to them—which means they see us redshifted as well. d) this statement doesn't make sense. the redshift means that we see the galaxy moving away from us, so observers in that galaxy must see us moving to them—which means they don't see us redshifted.

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r
