Using Hubble's law, determine the recessional velocity of a galaxy 700 Mly away. Use 22 km/s/Mly for the Hubble's parameter. Show your work for full credit
700 Mly * 22 (km/s)/Mly = ?
that is all you do to get this answer? i don't understand..
See if any of the following links will help you to understand better:
Count ibis is correct. That is what Hubble's "law" is all about.
More recent research has determined that velocity is NOT proportional to distance, however. The expansion rate of the universe is increasing.
if count ibis is correct the answer would be 15400 accroding to another person you would get 15, 022.9 which is correct?
I agree with rachel, which is correct????
