2. An energetic golden hamster (Mesocricetus auratus) is running at a constant speed on its frictionless exercise wheel (25.0 cm diameter,
weighing 25.0 g). If the hamster is considered part of the exercise wheel
system (his efforts are internal to the system), how much work is being
done on the hamster-wheel system?

Quantum mechanics applies to subatomic, atomic, nanometer-size, and micrometer-size systems. nanometer, micrometer, and kilometer-size systems. atomic, nanometer-size, and micrometer-size systems. subatomic, atomic, and nanometer-size systems.

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
