Question
question 1/ according to the hubble law the more distant galaxies _________. are older. have more mass. are fainter. are more elliptical. have more redshift.
Hubble's Law states that the recessional velocity of a galaxy is directly proportional to its distance from Earth ($v = H_0 d$, where $v$ is velocity, $H_0$ is Hubble constant, $d$ is distance). Greater distance means higher recessional velocity, which corresponds to more redshift (Doppler effect for light from receding objects). Other options (age, mass, faintness, ellipticity) are not related to Hubble's Law.
