1. For linear motion, we know that E kin = p 2 /2m. For angular motion (e.g. rotation), we can make the following assumptions: mass  moment of inertia I linear momentum  angular momentum L As a result, the rotational energy is (A) E rot = L 2 /2m (B) E rot = p 2 /2I; (C) E rot = L 2 /2I

3. For linear motion, you have seen how the deBroglie wavelength changes as the momentum of the particle changes (e.g. number of nodes for PIB). Consider a particle confined to the surface of a sphere, which can be described by the rigid rotator model. What do you expect for the shape of the wave function describing a pole-to-pole motion? (A) nodes form “circles of latitude” on the sphere; the number of nodes increases with angular momentum (B) nodes form “circles of latitude” on the sphere; the number of nodes decreases with angular momentum (C) nodes form “circles of longitude” on the sphere; the number of nodes increases with angular momentum (D) nodes form “circles of longitude” on the sphere; the number of nodes decreases with angular momentum
