Consider a giant molecular cloud (gmc) which has typical temperature and number density in its dense core of t = 10 k and n = 1010 m−3 . note that dense clouds are predominantly molecular hydrogen so that n = nh2 and rho0 = 2mhnh2 = 3 × 10−17 kg m−3 . calculate the jeans mass and jeans length for the gmc. note: you will need to estimate µ.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
