Complete this formal proof of Ex(P(x)v~P(x)) from the empty set. NOTE: similar to the rule above when instantiating quantifiers, if you need a random name, always start at the beginning of the alphabet. That is, use a first; only use b if necessary; etc.

Two capacitors are identical, except that one is empty and the other is filled with a dielectric (κ = 4.69). The empty capacitor is connected to a 11.0-V battery. What must be the potential difference across the plates of the capacitor filled with a dielectric so that it stores the same amount of electrical energy as the empty capacitor?
