It is always good to have an understanding of the magnitude of physical units. in physics, pressure is typically measured in units of pascals (pa). categorize each object according to the pressure it exerts when placed on a flat surface. assume that the bottom of each object is flat.

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?

An isotope undergoes radioactive decay by emitting radiation that has a –1 charge. what other characteristic does the radiation have?
