Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones. The antennae on your television set receive the signal, in the form of electromagnetic waves, that is broadcasted from the television station. It is displayed on your television screen.
Cathode-ray-type television screens, like the one in the video, create an image on the screen by accelerating charged particles (electrons) using an electric field. The electrons then pass between two steering coils made of copper wire. Currents running through the coils produce magnetic fields.
The TV signal is carried by wire to an antenna, which is often on a high mountain or building. The signal is broadcast through the air as an electromagnetic wave. These waves can travel through the air at the speed of light but not over very long distances.

A radar station, located at the origin of xz plane, as shown in the figure , detects an airplane coming straight at the station from the east. At first observation (point A), the position of the airplane relative to the origin is RA. The position vector RA has a magnitude of 360m and is located at exactly 40 above the horizon. The airplane is tracked for another 123} in the vertical east-west plane for 5.0s, until it has passed directly over the station and reached point B. The position of point B relative to the origin is RB (the magnitude of RB is 880m). The contact points are shown in the diagram, where the x axis represents the ground and the positive z direction is upward.

Define the displacement of the airplane while the radar was tracking it: RBA=RBRA. What are the components of RBA
Express RBA in meters as an ordered pair, separating the x and z components with a comma, to two significant figures.

Part A
Find the magnitude of the current I that will make the magnetic field at the center of the square equal to zero.
Part B
What is the direction of the current I (up or down)?

A constant potential difference of 12V is maintained between the terminals of a 0.25 micro-F parallel plate air capacitor. 
A. A sheet of Mylar is inserted between the plates of the capacitor completely filling the space between the plates. When this is done how much additional charge flows into the positive plate of the capacitor? (K for mylar = 3.1) 
B. What is the total induced charge on either face of the mylar sheet? 
C. What effect does the mylar sheet have on the electric field between the plates? Explain how you can reconcile thiswith the increase of charge on the plates, which acts to increase the electric field.
