You put a voltage across a metal wire and examine the progress of a group of electrons that begin at a certain point. You notice that after 4 seconds they have gone an average distance of 0.10 m in the +x direction through the wire and have spread out to the point where their standard deviation about this location is 10−3 m. They undergo 1012 collisions per second.
(a) What is the average distance gone in the +x direction between any two successive collisions?
(b) What is the standard deviation for the average distance traveled between any two successive collisions?
