Write a paragraph discussing the ethical dilemma in the following situation and identifying possible solutions: An insurance agent forgets to get the required signature from one of her clients who is buying an automobile insurance policy. The client acknowledges the purchase by giving the agent a signed personal cheque for the full amount. To avoid embarrassment and inconvenience, the agent forges the client's signature on the insurance application and sends it to the insurance company for processing.

For the simple, sinusoidally driven RC circuit of example 4.6 in the text, the particular solution for the current is given by eqn. 4.51 (p. 184), and the general solution is eqn. 4.54. Write this particular solution in phasor form. Next, analyze the circuit with impedances and the methods of Chapter 5 to solve for the steady-state current in phasor form. Then, plot this general solution and your found, steady-state current to see the agreement (or not) for the current of this circuit. What stands out to you in this case? (4.51) i_p (t) = 200 cos (200t) + 200 sin (200t) ?A which can also be written as i_p (t) = 200\sqrt{2} cos (200t - 45°) (In Chapter 5, we will learn shortcut methods for combining sine and cosine functions.) We obtain the homogeneous equation by substituting 0 for the forcing function in Equation 4.46 Thus, we have (4.52) RC \frac{di(t)}{dt} + i (t) = 0 The complementary solution is (4.53) i_c(t) = Ke^{-t/RC} = Ke^{-t/\tau} Adding the particular solution and the complementary solution, we obtain the general solution (4.54) i (t) = 200 cos (200t) + 200 sin (200t) + Ke^{-t/RC} ?A

1. A researcher has participants either take 0, 40, or 80 milligrams of caffeine and then measures how much their hands shake. In this hypothetical study, the independent variable is A) the amount of hand shaking B) the participants who take 40 or 80 milligrams of caffeine C) the participants who take for 0 milligrams of caffeine D) the number of milligrams of caffeine taken E) none of the above 2. In the scenario above, what would the dependent variable be? A) the amount of hand shaking B) the participants who take 40 or 80 milligrams of caffeine C) the participants who take for 0 milligrams of caffeine D) the number of milligrams of caffeine taken E) none of the above 3. Suppose Dr. Green finds the correlation between the number of letter in a person's name and that person's IQ score is $r = -.007$. Which of the following statements would BEST describe the relationship between these two variables on the basis of this result? A) As the number of letters in one's name increases, the likelihood that one has a high IQ decreases. B) The more letters in a person's name, the more likely they are to have a high IQ. C) The fewer letters in a person's name, the lower their IQ score. D) There appears to be no relationship between the variables because the correlation coefficient is so close to zero. E) None of the above statements describe the relationship.
