How much time would it take for an airplane to reach its destination if it traveled at an average speed of 790 kilometers/hours for a distance of 4700 kilometers? what is the airplanes speed in miles/hours?

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?

Does work output exceed work input when a machine is used? a) yes, it does, as machines create energy. b) it depends on the type of machine used. c) no, it doesn’t, as machines are inefficient. d) no, it doesn’t, as machines cannot create energy.

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?
