(b) now consider the scattering of a small projectile off a hard "sphere" (actually a hard disk) of radius r pinned down to the ice. find the differential cross section. (note that in two dimensions, hard "sphere" scattering is not isotropic.) (c) by integrating your answer to part (b), show that the total cross section is 2r as expected.

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
