If a Quasar Has a Recessional Velocity of 2

question 13

Multiple Choice

If a quasar has a recessional velocity of 2.7 × 10⁵ km/s and is determined to be 3600 Mpc, what is the Hubble constant based on this quasar alone? Hint: Note that the units of your result should be (km/s) /Mpc to see what arithmetic process you need to perform.

• A) 50 km/s/Mpc
• B) 9.7 × 10⁸ (km/s)Mpc
• C) 75 km/s/Mpc
• D) 0.013 km/s/Mpc
• E) 273,600 km/s/Mpc
