If the velocity of a moving object decreases from 60 m/s to 30 m/s, what happens to its momentum? it is reduced by half it stays the same it doubles it quadruples ill mark as brainliest

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

In a series circuit the __ is the same at every point

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?
