Physics

A parallel plate capacitor with plate separation d is connectedto a battery. The capacitor is fully charged to Q Coulombs and avoltage of V. (C is the capacitance and U is the stored energy.)Answer the following questions regarding the capacitor charged by abattery. For each statement below, select True or False.
With the capacitor connected to the battery, increasing ddecreases Q.
After being disconnected from the battery, inserting a dielectricwith Îº will increase V.
After being disconnected from the battery, inserting a dielectricwith Îº will increase C.
With the capacitor connected to the battery, inserting a dielectricwith Îº will decrease U.
With the capacitor connected to the battery, increasing d increasesU.
After being disconnected from the battery, decreasing d increasesC.
