Gelombang air laut membuat perahu yang berlabuh di dermaga bergerak naik turun. Deni menghitung gerakan naik turun perahu tersebut sebanyak 6 kali dalam 30 sekon. hitunglah periode gelombang air laut tersebut !

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
