Which statements are true about moving the compass around the wire? check all that apply. with no current, the compass needle will not move. if the light bulb is on, the compass needle will move. if the circuit is on, compass needle movement will indicate a dead battery. if current is flowing, the compass needle will not move unless the compass is touching the wire. changing the battery terminals will change the current flow and the compass will point differently.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
