Question 47
Easy

A distant galaxy has a redshift, zzz, of 0.042.

The speed of light, c=3.00×108 m/sc = 3.00 \times 10^8 \text{ m/s}c=3.00×108 m/s.

The recession velocity, vvv, of the galaxy is given by the equation:

v=z×c v = z \times c v=z×c

Calculate the recession velocity of this galaxy. Give your answer in standard form.
