:<span> </span><span>Under the assumption that a cell is made up of two concentric spheres you find the surface are of the inside sphere which will be your A.
You already have your separation and dielectric constant so just use the formula you stated towards the end of your question and you get 8.93x10^-11 Farads which is about 89pF</span>
Yes, the friction is acting in the opposite direction you are pushing.
D, all of these are voltage sources. A battery can power small things, generators can power larger things, and outlets can charge, or power things.
