How does sound get from one point to another?

1. sound travels as a wave from one point to another, and the particles in the medium move with the wave from one point to another.

2. a sound creates a wave that stays in place, but pushes particles in a medium from one point to another.

3. sound particles travel in a wave from one point to another to transmit the sound.

4. sound travels as a wave from one point to another, but particles in the medium do not move from one point to another.

An electron is traveling with initial kinetic energy k in a uniform electric field. the electron comes to rest momentarily after traveling a distance d. (a) what is the magnitude of the electric field

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?
