72) A coil with a self-inductance of 6.0 H is connected to a dc battery through a switch. As soon as the switch is closed, the rate of change of current is 2.0 A/s. What is the emf induced in this coil at this instant

If a 40 kg rock fell from a cliff and had a speed of 31.3 m/s when it hit the ground, what is it's kinetic energy?

Assume that a hockey player skates 60 feet in 3 seconds. What is the player's speed? If the hockey player travels this distance from East to West, what is his velocity?

How does friction slow things down?

A rock is thrown horizontally from the top of a radio tower lands 17.0 m from the base of the tower. if the speed at which the object was projected was 9.50 m/s, how high is the tower?

Why does a charged balloon stick to a neutral wall?

While the cart is moving along an aisle, it comes in contact with a smear of margarine that had recently been dropped on the floor. Suddenly the friction force is reduced for - 40.0 newtons to - 20.0 newtons.
