German physicist Werner Heisenberg related the uncertainty of an object's position (triangle)x to the uncertainty of its velocity (triangle)v. using plank's constant: The mass of an electron is 9.11x10^-31. What is the uncertainty in the position of the electron moving at 9.00x10^6 m/s. with an uncertainty of 0.01*10^6 m/?
Consider a system with four energy levels: 0E, 1E, 2E, 3E, where E is kT (E can be represented by epsilon and T is 100K). Assume that there are 10 particles. Provide an expression for energy, heat capacity and entropy. Plot all as a function of T
