Nerve impulses are carried along axons, the elongated fibers that transmit neural signals. We can model an axon as a tube with an inner diameter of 10 μm. The tube wall is insulated, but the fluid inside it has a resistivity of 0.50 Ω⋅m. Part A What is the resistance of a 6.0-mm-long axon? Express your answer with the appropriate units.
The membrane of
the axon of a nerve cell is a thin cylindrical shell of radius r-
10 m, length L 0.48 m, and thickness d 108 m. The membrane has a
positive charge on one side and a negative charge on the other, and
acts as a parallel plate capacitor of area A 2arL and separation d.
Its dielectric constant is about 7.

Exercise 9.45 - Enhanced - with Solution 19 of 24 > Constants Part A A thin, light wire is wrapped around the rim of a wheel, as shown in the following figure. The wheel rotates without friction about a stationary horizontal axis that passes through the center of the wheel. The wheel is a uniform disk with radius 0.252 m. An object of mass 4.00 kg is suspended from the free end of the wire. The system is released from...
