Question

Work is defined as the a. (a) mass times velocity b. (d) mass times velocity times distance c. (e) none d. (b) force times acceleration e. (c) mass acceleration Doppler's effect arises due to a. the motion of observer toward the source and the motion of the source toward the observer b. the stationary nature of the source c. (c) the stationary nature of the observer d. (d) all of (a), (b), and (c) If the distance between two gravitating objects doubles, the resulting force of attraction a. becomes four-fold b. drops to one-fourth c. (e) none d. becomes two-fold e. (d) drops to one-

Explanation / Answer

(2) The Doppler effect is due to the relative motion between the source and the observer. So, either observer or the source has to be moving relative to the other. Hence, the first option is correct.
