If the action potential starts with a potential difference of +40.0 mv, and the length constant of the axon is 2.00 mm, how far from the site of the stimulus will the potential difference across the membrane drop to 1.00 mv (assuming the action potential is not regenerated)?

Waves that cause the most damage during an earthquake are a. surface waves c. s waves b. p waves d. ocean waves

The electric potential a distance r from a small charge is proportional to what power of the distance from the charge? a. r^-1 b. r c. r^-2 d. r^2

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
