Consider a paramagnetic material made up of atoms, each with intrinsic magnetic moment of magnitude to with number density n atoms per unit volume. according to classical thermodynamics, the probability of each atom to be in a state of energy e is given by e p(e)=t exp (1) where t is the absolute temperature of the material, kp is the boltzmann constant, and t is a normalization factor determined by the requirement that the sum of all probabilities must be 1. if a magnetic field bo is applied to the material, quantum mechanics dictates that the atoms must be in one of two states: with magnetic moment parallel to the magnetic field, or antiparallel. the number of atoms in each state is governed by the above probability distri- bution. calculate the magnetization-magnetic moment per unit volume of this material, as a function of n, u, magnetic field magnitude bo, t, and assorted constants. disregard competing diamagnetic effects.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
