Which describes the average velocity of a unicycle going around in circles? check all that apply!

a. the total displacement divided by the time.

b. every time the unicycle returns to its starting point, the average velocity equals zero.

c. the slope of the acceleration vs. time graph.

d. the average acceleration divided by the time.

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.)

it is called kinetic energy
