Make a claim about the relationship between potential energy, kinetic energy, and speed whats your evidence I NEED THIS ASAP PLEASE (with actual answers not just random things to get points plz)

Using gravity, an elephant can pull a mouse towards it from the ground. true or false explain why. will give brainliest if answered fast and the best explanation

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?

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
