Explain what is physically meant by “Degrees of Freedom” and the “Equipartition Theorem”.

Expert Solution

Degrees of freedom, in a mechanics context, are specific, defined modes in which a mechanical device or system can move. The number of degrees of freedom is equal to the total number of independent displacements or aspects of motion. A machine may operate in two or three dimensions but have more than three degrees of freedom.

Law of Equipartition
It states “Total energy of a gas molecule is equally distributed among all the degrees of freedom”
Average Kinetic energy of a gas molecule per degree of freedom is 0.5kT

Explain what is meant by the Fisher Separation Theorem (FST). Graphically demonstrate FST for the case where an individual ends up lending in financial markets. Graphically analyse the effect of an increase in the interest rate on the utility of lenders. Discuss whether or not the lenders are better off as a result of the interest rate rise. Critically evaluate the assumptions upon which the Fisher Separation Theorem is based and assess the extent to which these limit its usefulness...
