  1. Consider a system of two Einstein solids, A=20 and B=20, sharing a total of 100 units of energy. Assume that the solids are weakly coupled, and that the total energy is fixed.

    1. How many different macrostates are available to this system?

    2. How many different microstates are available to this system?

    3. Assuming that this system is in thermal equilibrium, what is the probability of finding all the energy in solid A?

    4. What is the probability of finding exactly half of the energy in solid A?

A system of 6 identical 1-dimensional harmonic oscillators (it could be two atoms of an Einstein model solid). What is the probability that the first oscillator has 2 quanta of vibrational energy when the system has 3 quanta of vibrational energy? Hint: You may find it useful to consider how many microstates the system has and how many microstates the rest of the system has when the first oscillator has 2 quanta. Answer is 5/56 For the system considered in...

Consider the states of the combined total spin of two particles, each of which has spin 5/2 with ms= +5/2, +3/2, +1/2, −1/2, −3/2, and −5/2. (a) How many macrostates are there corresponding to the different values of the total spin if the particles are distinguishable? (b) If the two particles are distinguishable, what is the total number of microstates for all the allowed macrostates? (c) If the two particles are indistinguishable, what is the total number of microstates for...

1. Consider a 45-ball lottery game. In total there are 45 balls numbered 1 through to 45 inclusive. 4 balls are drawn (chosen randomly), one at a time, without replacement (so that a ball cannot be chosen more than once). To win the grand prize, a lottery player must have the same numbers selected as those that are drawn. Order of the numbers is not important so that if a lottery player has chosen the combination 1, 2, 3, 4...

Please summarize the below article in approximately 100 words: Monumental function in British Neolithic burial practices Ian Kinnes The high-risk rate of survival for the non-megalithic series of Neolithic funerary monuments, recently re-emphasized by Piggott (1973: 34), introduces a further variable into the deductive study of burial practices. In Britain and Europe the overall distribution of monumental forms present both lacunae and a marked preponderance of cairns over earthen mounds which are in ill accord with the known or predicted...
