Al entrar a una curva a 30 m/s un conductor reduce su velocidad con una aceleración de -4m/s ¿cual sera su velocidad de 3 segundos después de empezar a frenar? como le hago

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?
