The Moon (7.3x 10 22 kg) located at a distance of 4 x10 m from the center of the Earth (6.0 x 10 24 kg ). The moon gets thrown out of earth's orbit. What is the acceleration of the moon when it is thrown out of earth's orbit ? (Hint: What is the Force of Gravitational Attraction between the planets? How is force and mass related to each other?)​

How would you place two electrons on a sphere of radius r so that the electrostatic potential energy is minimized. how would you place three electrons to solve the same problem.

How have the competing explanations' experiments on atoms affected the development of the atomic model?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
