One of the great difficulties in landing on Venus is dealing with the crushing pressure of the atmosphere, which is 92 times the Earth’s atmospheric pressure.
(A) If you are designing a lander for Venus in the shape of a hemisphere 2.5 m in diameter, how many Newtons of inward force must it be prepared to withstand due to the Venusian atmosphere?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).
