Two long current-carrying wires run parallel to each other and are separated by a distance of 4.50 cm. If the current in one wire is 1.30 A and the current in the other wire is 3.20 A running in the opposite direction, determine the magnitude and direction of the force per unit length the wires exert on each other.

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.
