Q1. Find flux due to a point charge q on a rectangle of sides l x b at a distance r from the charge along the center of the rectangle.

Q2. A wave in the ocean has amplitude of 3 m. winds pick up suddenly increasing the waves amplitude to 6 m. How does this change in amplitude affect the wave's frequency and the amount of it transports?

Q3. An old trick to find out if a train is coming is to put your ear on the rails of the track. Why is this more effective than just listening for the sounds the train makes in air?
