A distant galaxy is moving away from Earth at a speed of 70,000 km/s. If a star in that galaxy emits light at a wavelength of 450 nm, what is the wavelength of that light when it reaches Earth? Speed of light c= 300,000 km/s.

The rate at which two galaxies are moving away from each other can be determined from Hubble's law. This speed can be estimated by multiplying the distance between the galaxies by the Hubble constant of 20 km/s/Mly. The formula isv Hod where Ho is the Hubble constant and d is the distance between the galaxies. A galaxy is 22 Mly away from the Milky Way. How fast is this galaxy moving away from the Milky Way in kilometers per second?...
