A 12 volt resistor is connected to a 400 ohm resistor. The circuit is temporarily disconnected and a 200 ohm resistor is added in series. Which of the following are true? Select all that apply.
The battery is producing more voltage due to more resistance in the circuit.
The current in the series circuit is 0.02 amps.
The total current in the series circuit is lower than the current in the initial circuit.
The voltage drop across the 400 ohm resistor is lower in the series circuit than it was in the simple circuit.

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.

Wish i knew this to !
