The Simple Quantity Theory of Money predicts that: changes in velocity bring about proportional changes in the price level. changes in the money supply will lead to proportional changes in the price level. changes in the price level bring about changes in the money supply. increases in real GDP are larger than changes in the price level if the money supply declines.

Dr. Noymer talked about some of public health's successes, as well as failures, regarding infectious diseases. Which of the following is false? - Historically, we saw a single type of dominating influenza A strain in circulation at a time. However, since 1977, we now have co-circulation of two influenza strains simultaneously. Having two strains in circulation at one time makes it much easier to develop successful flu vaccines because there are more viral components for the vaccine to target. - The word "quarantine" originates from the Italian word "quarantena," meaning forty days. This is due to the 40-day isolation of people on ships practiced as a measure of disease prevention related to the plague. - The main Samoan island successfully quarantined from the 1918 flu pandemic, whereas Western Samoa did not. The Western Samoa population experienced devastating infection rates and death as a result. - Vaccines are the biggest success story in public health, starting with the eradication of smallpox.

Problem 9-25: A uniform string of mass $\rho A$ per unit length is stretched to a length $l$ under a large tension P and is fastened between two fixed supports as indi- cated in Figure P9-25. The string is also subjected to a distributed transverse force $f(x, t)$ per unit length. Consider the transverse motion of the string. Derive the equation of motion and clearly indicate all geo- metric and natural boundary conditions. (Hint: For the potential energy function of the string, see Example L-4 in Appendix L.)

Question 1 (15 points) In class, we have discussed the flow of a Newtonian fluid inside a Couette viscometer, which contains a stationary inner cylinder of radius $\epsilon R$ and an outer cylinder of radius R rotating at angular velocity $\Omega$. In this question, we will analyze the steady-state flow of a Bingham fluid with viscosity $\mu_0$ and yield stress $\tau_0$ inside the Couette viscometer. (a) Write down the appropriate momentum balance. Justify your reasoning. (3 pt) (b) For $\tau_{r\theta} < \tau_0$, argue why the value of $v_\theta$ is zero. (3 pt) (c) For $\tau_{r\theta} > \tau_0$, solve for the velocity profile of $v_\theta(r)$. (5 pt) (d) Derive the torque of required to initiate the rotation of the outer cylinder. Once the rotation begins, explain how $\mu_0$ and $\tau_0$ can be determined. (4 pt)
