An axon is the relatively
long tail-like part of a neuron, or nerve cell. The outer surface of the axon membrane is charged
positively, and the inner surface is charged negatively. The membrane itself has a dielectric
constant k ~ 5 and a thickness d ~ 10−8 m. Thus the membrane is a kind of capacitor. Assuming
that the membrane acts like a parallel plate capacitor with a plate area of 5 × 10−6 m2, what is
