[W]? 4. A car changes its position from 52 km [W] to 139 km (E).
What is the car's displacement?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

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?

Boiling water is an example of physical change. true or false
