1. For the earth, an estimate of the variation of pressure with altitude above the surface of the earth is made for a gas of molecular weight, M, assuming the atmosphere is isothermal, the variation of g with altitude is negligible, and that the atmosphere behaves like an ideal gas. A significant error in this estimate arises from the assumption that the temperature of the atmosphere, T, is isothermal instead of decreasing with altitude. This decrease with altitude y in...

-8(0) dt 25.22 Suppose that a projectile is launched upward from the earth's surface. Assume that the only force acting on the object is the downward force of gravity. Under these conditions, a force balance can be used to derive, dυ R? (R + x)2 where v = upward velocity (m/s), t = time (s), x = altitude (m) measured upwards from the earth's surface, g(0) = the gravita- tional acceleration at the earth's surface (=...

8. A satellite is in circular orbit about planet Rosseforp at an altitude (above the surface) h. When h = 1.75 × 104 km, the period of the orbit is T = 12 hours. If Rosseforp has a mass of 7.0 × 1024 kg, what does the satellite weigh on the surface of Rosseforp if it weighs 850 N on the surface of Earth? You are part of an expedition to planet Rosseforp (same planet as in the previous question)....
