distant galaxy is simultaneously rotating and receding from the earth. As the drawing shows, the galactic center is receding from the earth at a relative speed of uG 5 1.6 3 106 m/s. Relative to the center, the tangential speed is vT 5 0.4 3 106 m/s for locations A and B, which are equidistant from the center. When the frequencies of the light coming from regions A and B are measured on earth, they are not the same and each is diff erent from the emitted frequency of 6.200 3 1014 Hz. Find the measured frequency for the

the total distance traveled by the car is

30km + 49km = 79 km .

this is an example of "committed" time.
