Abumper has a non negligible mass. after a collision with an ideal spring, the spring is compressed to a distance of 90% of the value of its distance when the bumper's mass was negligible. give a reasonable explanation for this decrease.

Write maxwell's equations and discuss the terms involved and the results of each equation in classical electrodynamics. if it is possible to write these equations in integral form, give the integral forms. find the wave equation for electromagnetic waves from the maxwell equations. what is the propagation velocity of electromagnetic waves in space according to the wave equation you find?
