Could someone please help me with this?

When two waves of same amplitude but differing frequencies are added together, the frequency of the amplitude modulation of the resulting wave is the difference b/w the frequencies of the two parent waves. How about beat frequencies from the interference of more than 2 waves, say 3, 4, or 10...

Also, just to clarify: The difference b/w a charged capacitor disconnected from a battery and one that is still connected to a battery is that the latter maintains a constant V across the capacitor regardless of distance d between the plates, and the former maintains a constant Q on the...

When you increase the charge Q on a capacitor, why don't you increase voltage V across it as well? Wouldn't higher Q increase E, and since V = Ed for a uniform E, V increases also? I know that for a uniform E across a capacitor, E stays the same regardless of distance d between the two plates...
