Using a value for Hubble's constant of 72 km/s/Mpc, find the recession velocity of a galaxy at a distance of 40 Mpc. Redshift of galaxy:
Added by Michelle A.
Step 1
We know that Hubble's constant (H0) is 72 km/s/Mpc. This means that for every megaparsec (Mpc) of distance, the recession velocity of a galaxy is increasing by 72 km/s. Show more…

The spectrum of a distant galaxy shows the H $\alpha$ line of hydro$\operatorname{gen}\left(\lambda_{\mathrm{rest}}=656.28 \mathrm{nm}\right)$ at a wavelength of $750 \mathrm{nm} .$ Assume that $H_{0}=70 \mathrm{km} / \mathrm{s} / \mathrm{Mpc}$. a. What is the redshift $(z)$ of this galaxy? b. What is its recession velocity $\left(v_{r}\right)$ in kilometers per second? c. What is the distance of the galaxy in megaparsecs?
A distant galaxy has a redshift $z=5.82$ and a recession velocity $v_{\mathrm{r}}=287,000 \mathrm{km} / \mathrm{s}$ (about 96 percent of the speed of light). a. If $H_{0}=70 \mathrm{km} / \mathrm{s} / \mathrm{Mpc}$ and if Hubble's law remains valid out to such a large distance, then how far away is this galaxy? b. Assuming a Hubble time of 13.8 billion years, how old was the universe at the look-back time of this galaxy? c. What was the scale factor of the universe at that time?
