Use the bohr quantization rules to calculate the energy levels for the harmonic oscillator, for which the energy is mw? 2m, that is, the force is mw^r. restrict yourself to circular orbits. what is the analog of the rydberg formula? show that the correspondence principle is satisfied for all values of the quantum number n used in quantizing the angular momentum.

Galileo was the first to notice that the moon has craters, valleys, and mountains. how might this have changed people's perception of the moon at the time?

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
