Derive the density of states of electrons in a three dimensional solid. Using this density of
states show that the specific heat of electrons (which is a fermion) in a three dimensional
solid is linear in temperature T.

Calculate the density of states function for a systemconsisting of alarge number of independent two-dimensional simple harmonic oscillator.Use an adaptation of the methods developed in"distribution function and densiy of states" for the 3D case

PLEASE PROVIDE CALCULATIONS

A protein can fold into four different conformations.

A) If the states are iso-energetic, and the system has 1 mole of protein equally mixed between the four states, what is the entropy change of forcing it all into a single confirmation on a per mole basis? (This might occur for example during the process of crystallization.)

B) Instead imagine that states B, C, D have a +1 kbT, +2 kbT, and +3 kbT energy increase compared to state A, respectively. What is the probability of finding the protein in each of the states?

C) For the system in part (B), now what’s the entropy change (on a per mole basis) of forcing the equilibrium mixture all to state A?

The City of Pfeiffer starts the year of 2017 with the general fund and an enterprise fund. The general fund has two activities: education and parks/recreation. For convenience, assume that the general fund holds $144,000 cash and a new school building costing $1,180,000. The city utilizes straight-line depreciation. The building has a 20-year life and no salvage value. The enterprise fund has $65,000 cash and a new $360,000 civic auditorium with a 30-year life and no salvage value. The enterprise fund monitors just one activity, the rental of the civic auditorium for entertainment and other cultural affairs.

The following transactions for the city take place during 2017. Assume that the city’s fiscal year ends on December 31.

Decides to build a municipal park and transfers $72,000 into a capital projects fund and immediately expends $20,600 for a piece of land. The creation of this fund and this transfer were made by the highest level of government authority.

Borrows $113,400 cash on a long-term bond for use in creating the new municipal park.

Assesses property taxes on the first day of the year. The assessment, which is immediately enforceable, totals $618,600. Of this amount, $525,800 will be collected during 2017 and another $51,600 is expected in the first month of 2018. The remainder is expected about halfway through 2018.

Constructs a building in the park in (b) for $40,000 cash so that local citizens can play basketball and other sports. It is put into service on July 1 and should last 10 years with no salvage value.

Builds a sidewalk around the new park for $10,000 cash and puts it into service on July 1. It should last for 10 years, but the city plans to keep it up to a predetermined quality level so that it will last almost indefinitely.

Opens the park and charges an entrance fee of only a token amount so that it records the park, therefore, in the general fund. Collections during this first year total $4,000.

Buys a new parking deck for $220,000, paying $22,000 cash and signing a long-term note for the rest. The parking deck, which is to go into operation on July 1, is across the street from the civic auditorium and is considered part of that activity. It has a 20-year life and no salvage value.

Receives a $110,000 cash grant for the city school system that must be spent for school lunches for the poor. Appropriate spending of these funds is viewed as an eligibility requirement of this grant. During the current year, $40,700 of the amount received was properly spent.

Charges students in the school system a total fee of $6,600 for books and the like. Of this amount, 90 percent is collected during 2017 with the remainder expected to be collected in the first few weeks of 2018.

Buys school supplies for $23,000 cash and uses $17,800 of them. The general fund uses the purchases method.

Receives a painting by a local artist to be displayed in the local school. It qualifies as a work of art, and officials have chosen not to capitalize it. The painting has a value of $83,700. It is viewed as inexhaustible.

Transfers $20,600 cash from the general fund to the enterprise fund as a capital contribution.

Orders a school bus for $102,000.

Receives the school bus and pays an actual cost of $105,000. The bus is put into operation on October 1 and should last for five years with no salvage value.

Pays salaries of $247,000 to school teachers. In addition, owes and will pay $30,800 during the first two weeks of 2018. Vacations worth $23,600 have also been earned but will not be taken until July 2018.

Pays salaries of $43,000 to city auditorium workers. In addition, owes and will pay $3,500 in the first two weeks of 2018. Vacations worth $5,800 have also been earned but will not be taken until July 2018.

Charges customers $150,800 for the rental of the civic auditorium. Of this balance, collected $127,600 in cash and will collect the remainder in April 2018.

Pays $10,400 maintenance charges for the building and sidewalk in (d) and (e).

Pays $16,200 on the bond in (b) on the last day of 2017: $5,800 principal and $10,400 interest.

Accrues interest of $15,000 on the note in (g) as of the end of 2017, an amount that it will pay in June 2018.

Assumes that a museum that operates within the city is a component unit that will be discretely presented. The museum reports to city officials that it had $48,500 of direct expenses this past year and $57,700 in revenues from admission charges. The only assets that it had at year-end were cash of $27,700, building (net of depreciation) of $346,300, and a long-term liability of $242,400.

Prepare the 2017 government-wide financial statements for this city. Assume the use of the modified approach.

Prepare a statement of net position. (Amounts to be deducted should be indicatedby a minus sign.)

During the presidential debate in 1990, the candidate Arnold (Democratic) won 22 states and Joseph (Republican) won 26 states. We are given that the states mean/average for Arnold came out to be 13.545 of the votes with a standard deviation of 10.591. On the contrary, Joseph had an average/mean of 8.423 of the votes with a standard deviation of 6.777. Please compute a 99% Conf. Interval for # of votes in a state a Democratic wins minus the # in a state a Republican wins.

Suppose that the one-year interest rate is 10 percent in the United Kingdom. The expected annual rate of inflation for the coming year is 4 percent for the United Kingdom and 7 percent for Switzerland. The current spot exchange rate is £:SFr = 3.75. Using the precise form of the international parity relations, compute the one-year interest rate in Switzerland, the expected Swiss franc to pound exchange rate in one year, and the one-year forward exchange rate.
