... When E(k) is as in problem 2, the semiclassical equations of motion are linear, and therefore easily solved. a) Assuming that the mean free time between electron collisions is τ , show that the DC conductivity is given by σ = ne2 τ M−1 b) Rederive the result of the problem 2 by finding explicitly th ...

mass on an incline - Feynman Lectures

... mass M2 hanging vertically as shown. The length of the cord is such that the masses can be held at rest both at height H/2. The dimensions of the masses and the pulley are negligible compared to H. At time t = 0 the two masses are released. (a) For t > 0 calculate the vertical acceleration of M2 (b) ...

Law of Conservation of Momentum

... pTOTAL (i ) pTOTAL ( f ) Momentum can be transferred from one part of a system to another, but the total amount remains constant. Momentum is conserved during any interaction among objects – collisions, explosions, etc. – since these interactions involve INTERNAL impulses (one part of the system ...
