Compute each part of given question:

Question: The thickness of a single membrane is about 7 nm. A myelin sheath consists of multiple membranes produced by coils of Schwann cell or oligodendroglia cells. Suppose a myelin sheath results from 100 membranes stacked on top of each other.

Part A: What is the specific capacitance of the myelin?

Part B: If the myelin sheath is a right circular cylinder 1 mm long, what is its total capacitance?

Part C: How much charge does it take to produce a voltage of -70 mV across this capacitor?

Part D: If the myelin were just 1 membrane--i.e, not myelin--what would be its capacitance? How much charge would it take to produce a voltage of -70mV across the single membrane?

Please help for the above question, completely confused!! Show each steps if possible, Thanks.
