Consider a polymer formed by connecting n disc-shaped molecules into a one-dimensional chain. each molecule can align along either its long axis (of length 2a) or short axis (length a). the energy of the monomer aligned along its shorter axis is higher by ε. that is, the total energy h=εu, where u is the number of monomers standing up. a) calculate the partition function, z (t, n), of the polymer. b) find the relative probability for the monomer to be aligned along its short or long axis. 3. calculate the average length, (l(t, of the polymer. 4. obtain the variance, (l(t, n)(t, n))^2. 5. what does the central limit theorem say about the probability distribution for the length l(t, n)?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
