Which answer best represents the system's change in energy for the following process? the system includes earth, two carts, and a compressed spring between the carts. the spring is released, and in the final state, one cart is moving up a frictionless ramp until it stops. the other cart is moving in the opposite direction on a horizontal frictionless track.

Which of these is not a possible type of energy transformation? a. electrical energy into light energy b. sound energy into nuclear energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

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?
