Aparallel plate capacitor (air filled) is connected to a 25 volt battery and left alone for a long time. the charge on the capacitor is 221 nanocoulombs. the battery is then disconnected, and the plates are pulled apart so that their separation distance is 3 times the original. what is the change in energy stored in the capacitor in micro-joules

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
