Homework chapter 11 with Solution Problem 11.23 Enhanced If an object on a horizontal frictionless surface is attached to a spring, displaced, and then released, it oscillates. Suppose it is displaced 0.124 m from its equilibrium position and released with zero initial speed. After 0.900 s, its displacement is found to be 0.124 m on the opposite side and it has passed the equilibrium position once during this interval.

Problem 19.03: Transmission of nerve impulses. Enhanced-with Solution < 10116 Constants Part A Nerve cells transmit electric signals through their long tubular axons. These signals propagate due to a sudden rush of Na ions, each with charge +e, into the axon. Measurements have revealed that typically about 5.8x1011 Na ions enter each meter of the axon during a time of 11 ms What is the current during this inflow of charge in a meter of axon?
