Each harmonic frequency is:
a. one more number times the fundamental frequency (i.e., fundamental frequency times two, times three, times four).
b. the fundamental frequency plus one more number (i.e., fundamental frequency plus one, plus two, plus three).
c. twice the previous frequency (second harmonic frequency is twice the fundamental frequency, third is twice the second).
d. any combination of two or more frequencies.
e. there is only one harmonic frequency.

Which of the following best describes why a white dwarf cannot have a mass greater than the 1.4-solar-mass limit?
A) Electron degeneracy pressure depends on the speeds of electrons, which approach the speed of light as a white dwarf's mass approaches the 1.4-solar-mass limit. B) White dwarfs get hotter with increasing mass, and above the 1.4-solar-mass limit they would be so hot that even their electrons would melt. C) White dwarfs are made only from stars that have masses less than the 1.4-solar-mass limit. D) The upper limit to a white dwarf's mass is something we have learned from observations, but no one knows why this limit exists.
