The holographic principle and this statement reproduce Newton's law of universal gravitation in a model developed by Erik Verlinde. This statement picks up a factor of 2 in the ultra-relativistic limit since kinetic energy is roughly equal to c times momentum. It’s not the fluctuation-dissipation theorem, but Nyquist used this law to derive an equation explaining Johnson noise. In the general form of this statement, the expectation of the quantity (-5[2])x times the derivative of the Hamiltonian with (15[1])respect to x equals (-5[1])(*) kT. This (-5[1])statement implies that an ideal gas has a constant (10[1])specific heat equal (10[1])to the number of degrees (10[1]-5[1])of freedom (10[3])times k over (-5[2])2. (10[1]-5[1])This statement only applies to degrees (10[1]-5[1])of freedom (10[1])that are quadratic in energy. (10[1])For 10 points, name this theorem which states that in thermal equilibrium, each degree of freedom (10[2])has an average energy (10[1])of one half kT. (10[2])■END■ (10[4]0[6])
