The cause of resistance to the flow of charge within an electrical wire is? . a) mobile charge carriers collide with atoms of the resistor. b) mobile charge carriers have mass (possess inertia) which resists their motion. c) the electric field that causes charge flow diminishes with distance. d) charge is consumed or used up as it flows through the wire.

b) mobile charge carriers have mass (possess inertia) which resists their motion

The correct answer among the choices listed is option B. The cause of resistance to the flow of charge within an electrical wire is the mobilecharge carriers have mass (possess inertia) which resists their motion. 

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.
