3. Evaluate the product lin=1(4k/2). Prove your answer. 4. Give an asymptotically tight bound for Ση=1 kr where r > 0 is a constant.
The atoms of a crystalline solid may occupy either a position of equilibrium, with zero displaced position, with energy >0. To each equilibrium position, energy, or a there corresponds a unique displaced position. Given N atoms and the total energy U, determine 2(U,N) the number of available microstates of this system.
