Which one of the following is correct information about G.E.R.L. system

Name the indirect sources of information about the interior of the earth.

In Rutherford's nuclear model of the atom, the nucleus (radius about 10^(-15)m ) is analogous to the sum about which the electron moves in orbit (radius about 10^(-10)m ) like the earth orbits around the sun. If the dimensions of the solar system had the same proportions as those of the atom, would the earth be closer to or further away form the sun than actually it is ? The radius of earth's orbit is about is 1.5xx10^(11)m . The radius of the sun is taken as 7xx10^8m .

What are different sources of information about the interior of the earth?

The earth revolves round the sun because the sun attracts the erth. The sun also attracts the moon and this force is about twice as large as the attraction of the earth on the mon. Why does the moon not revolve round the sun? Or does it?

Find the angular momentum of the earth (a) about the sun due to its orbital motion and (b) about its axis due to its spinning motion.
