When a solid sphere moves through a liquid, the liquid opposes the motion with a
force F. The magnitude of F depends on the coefficient of viscosity n of the liquid, the
radius r of the sphere and the speed of the sphere. Assuming that F is proportional to
different powers of these quantities, derive a formula for F using dimension analysis.

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object
