Determine the amount that would be reported in ending merchandise inventory on November 15 using the FIFO inventory costing method. Enter the transactions in chronological order, calculating new inventory on hand balances after each transaction. Once all of the transactions have been entered into the perpetual record, calculate the quantity and total cost of merchandise inventory purchased, sold, and on hand at the end of the period.

A particle in the infinite square well has the initial wave function $\Psi(x,0) = Ax(a-x)$. (a) Normalize this wave function. (b) Graph the wave function. (c) Which of the \"stationary states\" (i.e., $\psi_n(x)$ with definite energy) does it most closely resemble? On that basis, estimate the expectation value of the energy. (d) Compute $\langle H \rangle$ and compare this to your estimate in (c).

Consider an airline that faces two groups of travelers that have a different but constant price elasticity of demand. If the marginal cost per passenger is $60, how much should the airline charge each group of customers? (show the procedure to reach your results) (12pts) Vacation travelers Business travelers Elasticity 4 2 Price 7. The Museum of Fine Arts (MFA) in Boston normally charges $4 for admission. Suppose that the number of MIT students who visit the MFA is given by: Q = 6000 - 1000P and that the marginal cost of additional visitors is 0. a. Draw MIT's demand curve in the diagram below, and depict the equilibrium situation with the regular $4 admission price. (4pts) b. Why might it be reasonable to assume that MC = 0? (4pts) Consider two alternative ways of charging MIT students for admission to the MFA: Option A: Charge the normal price of $4. Option B: Collect a lump sum payment of $10,000 from MIT (financed by MIT out of student tuition revenues) and grant MIT students free admission. c. Complete the following table comparing the two options: (5pts) Consumer surplus (1) (2) Option A Option B Change (2) - (1) Producer surplus Combined (market surplus) d. How is it possible for Option B to make both MIT students and the MFA better off compared to Option A? (5pts)

Part 1: By using at least two types of aircraft engine (one from piston and one from gas turbine) produce a report with appropriate images and graphical representation, explaining all relevant characteristics of the thermodynamic and mechanical principles that apply during the operating cycles and the production of propulsive thrust. Two sets of data for a piston engine and gas turbine engine are provided in the tables below. Conclude your report by assessing the relative merits of both piston and gas turbine propulsion. TABLE-1 (Group A) For Piston Engine An aircraft reciprocating piston engine flying at a speed of 100ft/s, has a compressor compression ratio of 8. The pressure and temperature before compression are 100kPa and 300K respectively. The specific heat at constant volume is 0.718 KJ/kg.K and specific heat ratio is 1.4. The Calorific value of the fuel is 43MJ/kg and the mass flow rate of fuel is 9.52x10$^3$ kg/s. The mechanical efficiency of the piston engine is 90% and the propulsive efficiency of the propeller is 80%. The aircraft has a weight of 1338kg.
