A yellow ball with a mass of 2 kg is rolling across the floor at 3 mis. A red ball with a mass of 3 kg is rolling across th
same floor at 3 mis. Which ball has greater Kinetic energy, and why?

A) The yellow ball has greater kinetic energy, because it is rolling at a higher position above the ground.
B) The red ball has greater kinetic energy, because it has a greater mass.
C) The yellow ball has greater kinetic energy, because it is rolling at a greater speed
D) The red ball has greater kinetic energy, because it is releasing more thermal energy.

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?
