Two capacitors, one that has a capacitance of 6 µF and one that has a capacitance of18 µF are first discharged and thenare connected in series. The series combination is then connectedacross the terminals of a 12-V battery. Next, they are carefully disconnected so that they are notdischarged and they are then reconnected to each other--positiveplate to positive plate and negative plate to negative plate.
(a) Find the potential difference across eachcapacitor after they are reconnected.
1Your answer is incorrect. V (6 µFcapacitor)
2Your answer is incorrect. V (18µF capacitor)

(b) Find the energy stored in the capacitor before they aredisconnected from the battery, and find the energy stored afterthey are reconnected
3 µJ (beforedisconnected)
4 µJ(reconnected)

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.
