From the inclined plane of the figure take the whole system m1 and m2, make the free-body diagram and try to reach the expression of acceleration of the bodies. with m1 = 2m2 a = g (sinθ-1) / 3

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

Select all the correct answers. which three statements about electromagnetic radiation are true?

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?
