Question 1 20 pt Scientists at a pharmaceutical company want to compare their new drug to an existing one. Let's call the new drug A and the old drug B. In a random sample of 120 subjects who took drug A. 40% developed severe side effects. Whereas, in a random sample of 100 subjects who took drug B, 45% developed severe side effects. These scientists are interested to see if there is significant evidence that their new drug reduces severe side effects in patients at the a=0.05 significance level What is the correct set of hypotheses? OH, Pi-P=0 HP P2 <0 OH, Pi-P20 H. PIP20 OH: 10 HP - P<0

For the self-bias JFET configuration shown in the figure below: (15 pts) a. Sketch the transfer curve for the device. Then draw the network line (self-bias line) on the same graph. b. Determine I_(D_(Q)) and V_(GS_(Q)). c. Calculate V_(DS),V_(D),V_(G), and V_(S). d. Now determine I_(D_(Q)) using a purely mathematical approach. That is, establish a quadratic equation for I_(D) and choose the compatible solution. Also calculate V_(GS_(Q)) and compare it to the solution obtained in part (b).

(25 points) Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications of nuclear fission or nuclear technology, such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment, and is regulated by government agencies in order to protect human health and the environment. At the Connecticut Yankee nuclear power plant in Haddam and the Millstone Nuclear Power Station in Waterford, spent nuclear fuel (krw = 20 W/m·K) are presumably stored in a spherical container made of stainless steel with a kss = 15 W/m·K, an inner radius (ri) = 0.5 m and an outer radius (ro) = 0.6 m. Heat is generated volumetrically within the wasters at a uniform rate of 𝑞̇ = 105W/m3 , and the outer surface of the container is exposed to a water flow for which h = 1000 W/m2 ·K and T∞ = 25 oC. (a) Find the steady-state outer surface temperature, Ts,o (b) Find the steady-state inner surface temperature, Ts,i (c) Obtain an expression for the temperature distribution, T(r), in the radioactive wast

A hammer head H having a weight of 10N is moving downwards at 12 m/s when it strikes the head of a nail of negligible mass and drives it into a block of wood. Find the impulse on the nail if it is assumed that the grip at A is loose, the handle has a negligible mass, and the hammer stays in contact with the nail while it comes to rest
