WebThe radius and period of the Moon’s orbit was measured with reasonable accuracy thousands of years ago. From the astronomical data in Appendix D, the period of the Moon is 27.3 days = 2.36 × 10 6 s, and the average distance between the centers of Earth and the Moon is 384,000 km. Solution Solving for M E , WebExample 12.5 A 10 kg satellite circles earth once every 2 h in an orbit having a radius of 8000 km. Assuming that Bohr’s angular momentum postulate applies to satellites just as it does to an electron in the hydrogen atom, find the quantum number of the orbit of the satellite. Solution From Eq. (12.13), we have m v n r n = nh/ 2 π 2024-19
WebBohr radius. The Bohr radius ( a0) is a physical constant, approximately equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.291 772 109 03(80) × 10−11 m.
