A typical recreational scuba diver might fill his or her breathing tank with a mixture of nitrogen (P=136 atm) and oxygen (P=64 atm). Below is an equilibrium that exists between oxygen and nitrogen gases at 298 K: N2(g) + O2 (g) yields 2NO(g) K=4.1 x 10^-31. Nitrogen monoxide is a pretty nasty gas that will burn the lungs when inhaled in high enough concentrations. Should the diver be concerned about the toxic gas? The EPA recommends against NO concentrations greater than about 5 x 10^-8 atm for indoor air.

20 pts An insulated piston-cylinder device contains 5 L of saturated liquid water at a constant pressure of 175 kPa. Water is stirred by a paddle wheel while a current of 8 A flows for 45 min through a resistor placed in the water. If one-half of the liquid is evaporated during this constant-pressure process and the paddle-wheel work amounts to 400 kJ, determine the voltage of the source. 1000VA=1KJ/s Thermodynamics Property Tables are at the end of questions.

[Problem 1] (20 points) The impulse response and input signal are given by h(t) = e$^{-at}$u(t) and x(t) = t(u(t-t$_1$)-u(t-t$_2$)). Obtain the output y(t) = x(t)*h(t) by using the following methods. (a) Time domain convolution integration (b) Fourier transformation (c) By using y$^{(m+n)}$(t) = x$^{(m)}$(t) *h$^{(n)}$(t).

18. You are conducting an experiment to see if a given therapy affects test anxiety in a group of college students. A standard measure of test anxiety is known to produce a mean of 20. You want to test this claim. You find that a random sample of 54 college students has a mean anxiety score of 17 after taking a statistics exam. Assume the population standard deviation is 9. At $\alpha = 0.05$, can you support the claim? Write the answers to all steps with correct notation here. Show any calculations on your scratch paper. (8 pts.)

Explain ing regulators. 8. In its 2003 annual report, Honda Motor Company Ltd. states: Honda's manufacturing operations are principally conducted in 25 separate factories, 5 of which are located in Japan. Principal overseas manufacturing factories are located in the United States of America, Canada, the United Kingdom, France, Italy, Spain, India, Pakistan, the Philippines, Thailand, Vietnam, Brazil, and Mexico.... The company and its domestic subsidiar ies maintain their books of account in conformity with financial account- ing standards of Japan, and its foreign subsidiaries generally maintain their books of account in conformity with those of the countries of their domicile. The consolidated financial statements presented herein have been prepared in a manner and reflect the adjustments which are necessary to conform them with accounting principles generally accepted in the United States of America. (p. 59) Required: Discuss the possible reasons for Honda to prepare its consolidated financial statements in conformity with U.S. GAAP.
