Question
As measured by NASA’s Viking landers, the atmosphere
of Mars, where g ≈ 3.71 m/s 2 , is almost entirely carbon
dioxide, and the surface pressure averages 700 Pa. The temperature
is cold and drops off exponentially: T ≈ T o e - Cz ,
where C = 1.3E-5 m - 1 and T o = 250 K. For example,
at 20,000 m altitude, T ≈ 193 K. ( a ) Find an analytic
formula for the variation of pressure with altitude.
( b ) Find the altitude where pressure on Mars has dropped
to 1 pascal.
