A real cubic expansivity is an increase in the volume of a liquid per unit volume per degree rise in temperature when heated in an inexpansible vessel.
An object that's moving doesn't necessarily change its speed or acceleration. Also, the force applied to it doesn't need to change ... in fact, a moving object doesn't need ANY force applied to it in order to keep moving.
But any moving object WILL have a change in its position ... THAT's how you know it's moving, and that's WHY you say "It's moving !". (choice-B)

Explanation:
1) An electron is moving east in a uniform electric field of 1.53N/C directed to the west. At point A, the velocity of the electron is 4.51�105m/s pointed toward the east. What is the speed of the electron when it reaches point B, which is a distance of 0.400m east of point A? 2) A proton is moving in the uniform electric field of part A. At point A, the velocity
