Will rate! Consider a particle of mass m that can move freely along the x-axis from -(a)/(2) to +(a)/(2), but which is strictly prohibited from being found outside this region. The wave function of the particle within the allowed region is known as psi (x)=Acos((pi x)/(a)). (a) What is the energy E in this allowed region? (b) What is the value A in the wave function? (c) What is the probability of finding this particle between 0 and +(a)/(4) ? 6.

Draw the major 1,2- and 1,4-addition products obtained in the reaction shown. Assume that both are derived from the most stable carbocation intermediate. HCI • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • If the 1,2- and 1,4- addition products are the same due to symmetry, only draw one structure. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate multiple products using the + sign from the drop-down menu.

Buchanan Industries is evaluating a proposal to install solar panels on the roof of its factory near Huntsville. The panels will cost $540,000 per set. Depending on the price of electricity and the efficiency of the panels, the project will increase net operating cash flows by either $86,000 per year or $170,000 per year with a 67% likelihood that the lesser outcome will occur. The useful life of the panels is 6 years. If early results indicate savings of $170,000 per year, 3 additional sets of panels will be installed next year at the same cost and with the same projected increase in net operating cash flows. What is the expected NPV of the project (in $ thousands, rounded to one decimal place, e.g., 12.3) including the option to expand, given a discount rate of 12%? Answer should be 68.0.

QUESTION 11 Explain why economic profits in all perfectly competitive markets will tend toward zero in the long run. QUESTION 12 Explain how a perfectly competitive market causes allocative efficiency to occur. What is the mathematical requirement for allocative efficiency? Why is this requirement met in perfect competition and in no other market structure?
