WebThe Hubble law indicates that a) the Milky Way Galaxy appears to be at or near the center … WebTo be able to compute a meaningful distance from the Hubble law, we must deal with galaxies for which the expansion velocity is much greater than these random velocities: at least 5000 km/s. What is the distance corre- sponding to this speed of 5000 km/s? The Hubble Law tells us that v = H0d.

WebPhysics Physics questions and answers If the Hubble constant is 70 km/s/Mpc, how far away is a quasar that has an apparent velocity of recession of 96,000 km/sec? (Hint: Use the Hubble law.) Mpc This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebHubble's Law, when written in this form, $$ v = H_0D, $$ means: if $D$ is the current distance of a galaxy, and $H_0$ the Hubble constant, then $v$ is the current recession velocity of the galaxy. So it tells you what the recession velocity of a galaxy is right now, not what it was in the past. WebD. Hubble's law is a relationship between galaxy speeds and galaxy distances. This relationship can be shown as a line on a graph of speed versus distance. Each of the following four graphs shows a possible relationship expressing Hubble's law.
