A rollercoaster moves from the bottom of a hill and approaches the top of the hill. If friction between the wheels and the track is ignored, which statement describes the components of the total energy?

The kinetic energy decreases, and gravitational potential energy increases.

Explanation:

The rollercoaster will slow down as it goes up the hill, so kinetic energy should not increase.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

correct it is c.) b b
