Two infinite, flat, parallel, and perfectly conducting metal plates lie in the planes . the space between the plates acts as a cavity oscillator in which 2aythe electric field is given by: , where is a unit vector in 0(/eecosyasintk)k)the direction of z-axis. (a)assuming that is in the x-direction, apply ampere’s to bobtain the magnetic field everywhere inside the cavity region.(b) use ampere’s law to compute the current per meter on the metal surface, and compare with the displacement current per meter between the plates.

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)
