5. A star whose temperature is 8000 K has a peak wavelength of 362.5 nm, according to
Wien's Law. If the star is in the Andromeda Galaxy, which is moving towards us at about
402,000 km/hour, what would an observer on Earth see as the peak wavelength for this
star (show your work, and use c = 300,000 km/s)?
