please answer question 8-13
This is the prior information: Nerve impulses are electrical
currents in the form of “ionic flows.” Therefore the electrical
properties of the axon are important to understand in order to
understand the flow of electrical impulses. In this test, you will
explore the capacitance and resistivity of an axon of a nerve cell.
For this test, the axon will be treated as a CYLINDER of arbitrary
length “L” and radius “a” that is filled with a...

A nerve signal is transmitted
through a neuron when an excess of Na+ ions suddenly enters the
axon, a long cylindrical part of the neuron. Axons are
approximately 10 μm (10x10-6 m) in diameter, and measurements show
that about 5x1011 Na+ ions per meter (each of charge +e) enter
during this process. Although the axon is a long cylinder, the
charge do not all enter the axon at the same time. A plausible
model would be a series of point...

3. An electric circuit consists of a battery, three 2 12 resistors and a 10 A fuse. 12V 2Ω Calculate the total current out of the battery. If the current through the fuse exceeds 10 A, assume that it melts and opens the circuit. a) Determine the amount of charge that flows between the top two resistors at point B during a period of 5 seconds. b) c) Assume that the potential on the batteries positive terminal to be 12...

answer question 3-4
40. Heart-lung machines and artificial kidney machines BIO employ electromagnetic blood pumps. The blood is con- QIC fined to an electrically insulating tube, cylindrical in prac- S tice but represented here for simplicity as a rectangle of interior width w and height h. Figure P28.40 shows a rect- angular section of blood within the tube. Two electrodes fit into the top and the bottom of the tube. The potential difference between them establishes an electric current...
