If 10 j of work (electric potential energy) is used in pushing 2 c of charge into an electric field, its electric potential relative to its starting position is a. less than 5 v c. more than 20 v. d. 20 v

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up

Both independent and dependent clauses

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
