Consider a gas of free and independent electrons in two dimensions a- show that the electron density of states (w( is independent of the electron kinetic energy b- calculate the fermi energy at t 0k° c- calculate the average electron kinetic energy at t-ok" c- calculate the heat capacity at very low temperature

Who was the first scientist to measure speed as distance over time?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
