Why would we expect protogalactic clouds with relatively high density to form an elliptical galaxy rather than a spiral galaxy?
A. The higher density allows the protogalactic cloud to cool slower
B. The higher density increases the gravitational potential energy
C. The higher density allows the protogalactic cloud to cool faster
D. The higher density increases the total angular momentum

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
