After the introduction of new drug treatments in 1992, U.S. deaths from AIDS dropped in all ethnic groups starting around 1995. However, the number of deaths due to AIDS worldwide did not start to drop until 2006. Which of the following statements gives a reasonable explanation for why this occurred? The use of drugs has mutated the strain of HIV found in the United States such that it has become less deadly than the strains of HIV found in other parts of the world. O The drop in worldwide deaths due to AIDS is actually because there has been a drop in the overall worldwide population since 2006. With the overall population going down, the number of deaths due to any cause will go down as well.

Infinite flat conducting plates are located at z = 0 mm and z = 2mm, respectively. The region between the plates is filled with mica. The bottom plate is charged to a potential of 300 V and the top plate is charged to a potential of 1500 V. The plate area is 2 cm$^2$ a. Solve Laplace's equation in z for the potential anywhere between the plates (assume the dielectric strength is infinite for part a) through d). b. Find the total charge on the top plate c. Find the total charge on the bottom plate d. What is the capacitance of the capacitor. e. For the actual mica-filled capacitor, is dielectric breakdown occurring?
