1. What are the differences and similarities between the quantization of angular momentum in the Bohr model and the Schrödinger theory?
2. Can the magnetic moment of an atom line up exactly with an external magnetic ?eld? Explain.
3. What are the possible magnetic quantum numbers for an f state?
4. List all the reasons why a fourth quantum number (intrinsic spin) might have helped explain the complex optical spectra in the early 1920s.
5. Is it possible for the z component of the orbital magnetic moment to be zero, but not the orbital angular momentum? Explain.
Determine the group and phase velocity of 8 MeV protons and 8 MeV electrons. For the phase velocity, find both the relativistic and non-relativistic results
Sally travels by car from one city to another. She drives for 30.0 min at 69.0 km/h, 37.0 min at 34 km/h, and 54min at 74.0 km/h and she spends 13.0 min eating lunch and buying gas.

Calculate the fluid force (in Newtons) on a square plate with aside of 2 m that is submerged at ahorizontal angle of 30°. Assumethat the top edge of the plate is located at the surface of the water.
Two moles of helium are initially at a temperature of 30.0C and occupy a volume of 3.20×102m3 . The helium first expands at constant pressure until its volume has doubled. Then it expands adiabatically until the temperature returns to its initial val..
