(a) Calculate the frequency of revolution and the orbit radius of the electron in the Bohr model of hydrogen for n 100, 1000, and 10,000. (b) Calculate the pho- ton frequency for transitions from the n to n 1 states for the same values of n as in part (a) and compare with the revolution frequencies found in part (a). (c) Explain how your results verify the correspondence principle.

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

Wavelength of 125 meters is moving at a speed of 10 m/s. what is it's frequency?

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
