mostly concerned with B and C.

The density of atmospheric air varies with elevation, decreasing with increasing altitude. (a) Plot the density of air ( $$y$$-axes) versus the elevation (x-axes). (b) Using the data given in the table, obtain a relation for the variation of density with elevation, and calculate the density at an elevation of $$7000\mathrm{m},14000\mathrm{m},21000\mathrm{m}$$, and $$28000\mathrm{m}$$. (c) Calculate the mass of the atmosphere using the correlation you obtained. (d) Explain the validity of your solution. (Very briefly, max five lines.) Assume the earth is a perfect sphere and the diameter of the Earth is about $$12750\mathrm{km}$$, and also take the thickness of the atmosphere to be $$28\mathrm{km}$$.
