What si earth is made up of protons and moon is of electrons...class bata de pgli |

Answer» Answer: the earth ismade entirely of a single material (say iron), then things are pretty easy. An iron nucleus contains 26 protons and 30 neutrons. Thus the mass of an iron nucleus is (56 x mass of a proton) = 9.4 x 10^-26 kg. And then the earth would have 6.4 x 10^49 iron atoms in it. On one level, it makes a kind of sense; after all, electrons orbit protons, and moons orbit planets. ... If you PUT 1052 electrons together—to build a Moon—they push each other apart really hard. In FACT, they push each other apart so hard, each electron would be shoved away with an unbelievable amount of energy. |
