You pull into a gas station and fill up your car with gasoline. during the time you are filling up, the car has
a)kinetic energy only. b)potential energy only. c)both potential and kinetic energy. d)neither potential or kinetic energy.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
