Assumption of Drude Model are,
1. Between collisions , electron interactions with other electrons and the ions are neglected.
2. Collisions are instantaneous, abruptly changing velocity.
3. Electrons collide with probability 1/relaxation time per unit time .
4. Electrons are in thermal equilibrium with their surroundings.
5. Electrons move in straight lines between one collision and another.
1. (5 points) Please provide five assumptions used in developing the Drude model.
The neoclassical model of labour supply is based on a number of assumptions. List and discuss any five assumptions that you think are most unrealistic for modelling the labour supply decisions made by workers in a developing country such as South Africa.
The Drude model can be used to estimate the force constants, vibrational frequencies, and related properties in metals. We use a crude model to describe the vibration of a single ion in a monovalent metal: The ion is assumed to be a positive point charge in a spherical unit cell that is filled with electrons of the appropriate density n. All the rest of the crystal is ignored. (a) Consider a small displacement of the ion from the center of...
What is the purpose of an economic model? Why do economists make assumptions in developing models?
2. (5 points) Consider the following regression model with the usual assumptions (a) Assume that the columns of n x p dimensional X in the model are orthogonal. Show that B and B, (i A j) are independent (b) Suppose that an extra term uy is added to the model Assume that u is orthogonal to the columns of X. Show that B in the extended model is equal to B in the original model.

Tony Stark is developing a new model of the Iron Man suit. His previous suit model uses an average of 222.4 kilowatts per second, and he wishes to see if his new model is more efficient in other words, if the mean kW/s used is lower than the previous model). He takes a sample of five randomly selected suits made under the new model and finds that the mean amount of energy used is 210.2 kW/s with a standard deviation...
