Unformatted text preview: Name:__________________________________________ Date:__________________________ PHYS 360 Lecture Question #37 Consider a copper wire. Connect a battery across the ends, and a current will flow. This means that electrons are able to move in the direction of the (electron) current, and the distances travelled are large compared to the distance between atoms. 1. This happens because there is a force that takes bound electrons and pulls them away from the atomic core, allowing these atoms to move. True False 2. This happens because in a metal there is no force of attraction between the atomic cores and the outer electrons. True False 3. This happens because there is no force between the outer electrons themselves, even when they are moving together in the current. True False 4. Obviously the reason must be due to quantum mechanics. It is simply the result of non ­local nature of entangled states. True False ...
