Suppose that two stars are identical in every wayfor example, same distance, same mass, same temperature, same chemical composition, and same speed relative to Earthexcept that one star rotates faster than the other.
 
  Spectroscopically, how could you tell the stars apart? A) The faster rotating star has wider spectral lines than the slower rotating star.
  B) The faster rotating star will have an emission line spectrum while the slower rotating star will have an absorption line spectrum.
  C) The peak of thermal emission will be at a shorter wavelength for the faster rotating star than for the slower rotating star.
  D) There is no way to tell the stars apart spectroscopically, because their spectra will be identical.

Question 2
