Physics

The thickness of a single membrane is about 7 nm. A myelinsheath consists of multiple membranes produced by coils of Schwanncell or oligodendroglia cells. Suppose a myelin sheath results from100 membranes stacked on top of each other.
A) What is the specific capacitance of the myelin?
B) If the myelin sheath is a right circular cylinder 1 mm long,what is its total capacitance?
C) How much charge does it take to produce a voltage of -70 mVacross this capacitor?
D) If the myelin were just 1 membrane--i.e, not myelin--whatwould be its capacitance? How much charge would it take to producea voltage of -70mV across the single membrane?
