In studying a voyage to theMoon in Chapter 3 we somewhat arbitrarily started at a height of 50 kilometers above the
surface of the Earth.
(a) At this altitude, what is the density of the air as a fraction of the density at sea level?
(b) Approximately how many air molecules are there in one cubic centimeter at this altitude?
(c) At what altitude is air density one-millionth (1 × 106) that at sea level?
