Answer Key / Explanation : (d) -
|
(d) When earth moves round the sun then according to Kepler’s second law, the radius vector drawn from the sun to earth, sweeps out equal areas in equal time, |
its areal velocity (or the area swept out by it per unit time) is constant. While in such motion, angular velocity, kinetic energy and potential energy change.127 votes
