Consider a rigid body with moment of inertia i, which is constrained to rotate in the xy plane, and whose motion is given by the schrödinger equation, a) find the eigenfunctions and eigenvalues. b) assume the rotator has a fixed dipole moment p in the plane. an electric field e is applied to the plane. find the changes in energy levels to first and second order in the field.

A175 g lump of molten lead at its melting point (327 c) is placed into 55.0 g of water at 20.0 c. the specific heat of lead is 130.j/kg c and the hf of lead is 20,400 j/kg. when the lead and the water have reached equilibrium, what is the temperature of the mixture?
