Q1. A dielectric-filled parallel-plate capacitor has plate area = 40.0cm^2, plate separation = 5.00mm and dielectric constant = 6.00. The capacitor is connected to a battery that creates a constant voltage = 10.0 V. all through the problem, use = 8.851016 .The dielectric plates is now slowly pulled out of the capacitor that remains connected to the battery. The dielectric plate is now slowly pulled out of the capacitor that remains connected to the battery. Find the energy of the capacitor at the moment when the capacitor is half-filled with the dielectric.

Q2. The radar system at an airport broadcasts 15 GHz with 150 kW. An approaching airplane with a 34 m^2 cross section is 24km away. Assume that the radar broadcasts uniformly in all directions and that the airplane scatters microwaves uniformly in all directions.
