48. Calculate the kinetic energy that the planet has because of (a) its rotation about its very own axis and (b) the motion approximately the sun. Assume the the earth is a uniform sphere and also that its path approximately the sun is circular. Because that comparison, the complete energy provided in the United states in one year is about 1.1 x 1020 J. |
