A company expects to purchase 10,000 barrels of oil in 3 months. The current spot price of oil is $75 per barrel, and the 3-month futures price is $76 per barrel. The company wants to hedge against a potential rise in oil prices by using futures contracts. Each futures contract represents 1,000 barrels of oil. 1. How many futures contracts should the company buy to hedge its position? 2. If the spot price of oil rises to $80 per barrel at the end of 3 months, calculate the net cost of purchasing the oil after accounting for the futures hedge.

EXERCISE 2.14 Consider the double square well, with a single well described with the parameters $a = 3 \AA$, $m = 1 \ m_e$, and $V_0 = 10 \text{ eV}$. If the two wells are far apart, there are two energies very near the energy of a single well. Why? Investigate the dependence of these energies as the wells are brought nearer to one another.

Problem 1 (40 pts): Wind blowing past a flag causes it to \"flutter in the breeze.\" The frequency of this fluttering, $\omega$ (with dimension of T?¹), is assumed to be a function of the wind speed, V, the air density, $\rho$, the acceleration of gravity, g, the length of the flag, l, and the \"area density,\" $\rho_a$, (with dimensions of ML?²) of the flag material. It is desired to predict the flutter frequency of the large l = 40 ft flag in a V = 30 ft/s wind. To do this, a model flag with l = 4 ft is to be tested in a wind tunnel. a) It has been shown that $\omega = f(V, \rho, g, l, \rho_a)$. Express each parameter in terms of its primary dimensions using the MLT system. (3 pts) b) How many nondimensional parameters are expected to fully describe this problem? Show how you arrived at your answer. (2 pts) c) Show that l, g, and $\rho$ meet the criterion of being selected as repeating variables. (4 pts) d) Using l, g, and $\rho$ as repeating variables, and the linear equations method, develop the $\Pi$ term. Make $\Pi_1$ contain the dependent variable ($\omega$). (8 pts)

Consider the following PL/SQL script: SET SERVEROUTPUT ON BEGIN INSERT INTO COURSE (course_no, description, created_by, created-date, modified_by, modified_date) VALUES (course_no_seq.nextval, 'database development', USER, SYSDATE); COMMIT DBMS_OUTPUT.PUT_LINE ('One course has been added'); END; Assumptions: All the COURSE table fields have check constraints defined on them indicating that none can be null. 1. Explain why the script does not execute successfully. (3 marks) 2. Add a user-defined exception to the script, so that the error generated by the INSERT statement is handled. Assign the code 2290 to this exception. (5 marks)
