The classical energy of a plane rotator is given by 1l2 2 i where l is the angular momentum. apply the bohr quantization rule of angular momentum to obtain the energy levels of this "quantum" rotator.

The movement of electrons between atoms is called an

Which is an example of an exothermic process?

An electric power distributor charges residential customers $0.10 per kilowatt-hour (kwh). the company advertises that "green power" is available in 150 kwh blocks for an additional $4 per month. (green power is generated from solar, wind power, and methane sources.) if a certain customer uses an average of 391 kwh per month and commits to one monthly 150 kwh block of green power, what is her annual power bill
