Draw the structure(s) of the major organic product(s) of the following reaction. H + OH HO HCI • You do not have to consider stereochemistry. • If a compound is formed more than once, add another sketcher and draw it again. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate multiple products using the + sign from the drop-down menu.
A neighborhood contains 5 coffee shops, 5 pizza restaurants, and 5 sushi restaurants. Three of the businesses are to be chosen at random. Of the total number of possible outcomes, how many would consist only of pizza restaurants shops?
In the region $x \ge 0$ there is an electrostatic potential $V(x) = x \exp(-\lambda x)$ where $\lambda > 0$. a) What is the electrostatic field in this region? b) Is there a point for which the electrostatic field is a relative maximum? c) What is the electrostatic field at $x \to \infty$? d) What can you say about the charge density $\rho(x)$? Is it positive? Negative? Both? The electrostatic field should give you some idea. If you recall how to calculate this, do so.
Determine the STFT $X_r(j\omega)$ for the signal $x(t) = \sqrt{a}e^{-at}$, $a > 0$, using a unit energy rectangular window $h(t) = \begin{cases} 1/\sqrt{T} & 0 \le t \le T \\ 0 & \text{otherwise} \end{cases} = \frac{1}{\sqrt{T}} rect(\frac{t - T/2}{T})$. Attempt to demonstrate in your result that the high frequency content occurs primarily around time near zero.

Imagine for a moment that you have obtained a leadership position in the newly formed International Sports Governing Organization (ISGO). This group has been tasked with developing rules and regulations that apply across all professional sports. One of the first issues on their agenda is the use of performance-enhancing drugs. Some members of ISGO advocate legalizing performance-enhancing drugs to promote athletes' autonomy and eliminate inconsistencies in how punishments for using these drugs are administered. Other members of ISGO fear that legalizing performance-enhancing drugs would promote inequality and undermine the spirit of competitive sport. As a member of this board, do you vote in favor of legalizing performance-enhancing drugs or keeping them illegal? Why? How do you respond to the objections that have been voiced to your position by other members of ISGO? If you favor keeping some performance-enhancing drugs illegal, then what criteria do you use to distinguish between those that are permissible to use and those that aren't? And why?
