1. How high would the atmosphere extend (assume P=0 at the top) if it were uniform density Pair - 1.29 kg/m3 and we assumed the air was incompressible (Patm = 1.013 x 10e5 Pa



2. maybe roh g h?



3. I dont have any idea where to start with this. There are a few ideas in there that i just dont know where my teacher is going. This is a test review and we did not have a question quite like this in the homework or notes./b]

Think about what rho g h equals

if P = roh g h
1.013 x 10e5 pa= 1.29kg/m3 x 9.8m/s2 x h
h = 8012.97 m?

It's correct. You ought also to have been told to assume g is constant to that height.
