What is the difference between velocity and acceleration? A.
Velocity describes an object's position and acceleration describes how fast it moves.
B.
Velocity is how fast an object moves and acceleration is the rate of change in velocity.
C.
Velocity is used to determine the magnitude of force acting on an object, and acceleration isn't.
D.
Velocity is a time-dependent property of an object, while acceleration is not.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
