Write a program, in a file named indentation_print.py, which reads many lines from the user, in a loop; the easiest way to do this will be an infinite loop: while True: which uses break to end the loop when needed. For each line of input, count how many spaces there were at the beginning of the line, and print that out. (Note that some lines might have no leading spaces, and some might be entirely empty.) Terminate your loop when the user types quit on any input line. For this check, you should ignore all whitespace (that is, the user might type many spaces before and after quit), but only quit if quit is the only non-whitespace text on the line. You may assume that the input will always eventually include a quit line. NOTE: Do not count the indentation on the quit line. Simply break that loop at that point, without counting.

54. If $f: A \to B$ and $g: C \to B$ such that $A \subset C$ and for each $a \in A$ we have \newline $f(a) = g(a)$ then $g$ extends $f$. We also say that $f$ extends to $g$. Assume that \newline $f: S \to \mathbb{R}$ is a uniformly continuous function defined on a subset $S$ of a metric \newline space $M$. \newline (a) Prove that $f$ extends to a uniformly continuous function $\overline{f}: \overline{S} \to \mathbb{R}$. \newline (b) Prove that $\overline{f}$ is the unique continuous extension of $f$ to a function defined \newline on $\overline{S}$. \newline (c) Prove the same things when $\mathbb{R}$ is replaced with a complete metric space \newline $N$.

Directions: Answer all questions completely and show all work. Correct answers with no work shown will receive no credit. Be sure to round all probabilities to five decimal places (three if using a percentage) and all other numbers to three decimal places except where not necessary. 1. This problem will consider the chance experiment of spinning a fair coin and rolling three standard dice. (a) Let S represent the sample space. Express S in set notation. (b) Denote by E the event that occurs when the coin lands heads up and the sum of the sides of the dice facing up is larger than 10. Find P(E). Hint: How many possible rolls have a total larger than 10? (c) Denote by F the event that occurs when the coin lands heads up and the sum of the sides of the dice facing up is smaller than 14. Find P(F). (d) Let E and F be as described above. Find P(E\cap F) and P(F<sup>c</sup>). Are E and F mutually exclusive? Explain. 2.

QUESTION 15 When using the two probes (leads) that you connect to your multimeter in order to read electrical values on devices in your circuit, how must you wire the multimeter with a device in order to accurately read the device's electrical current? In series. Both series and parallel simultaneously. In parallel. It doesn't matter, just touch the probes to either side of the device you wish to measure. QUESTION 16 What is the frequency of a 570nm photon? Do not include units on numerical answers. If you intend to use scientific notation, use E to represent "x10^." For example: 3.7x10^-2C should be input as 3.7E-2C

(6) Feedback Amplifier's. Answer both parts A and B for full credit (2+2=4 points) A) For the feedback voltage amplifier of Fig. below, let the op amp have an infinite input resistance, a zero output resistance, and a finite open-loop gain of 1000 V/V. If $R_1$ = 10 ?? what value should $R_2$ have to obtain an ideal closed-loop gain of 10? Now, calculate the loop gain $A\beta$ and use it to find the actual value of the closed-loop gain $A_f$. If $A_f$ is to be exactly 10, what must the value of $R_2$ be? B) A feedback amplifier utilizing voltage sampling and employing a basic voltage amplifier with a gain of 1000 V/V and an input resistance of 1000 ? has a closed-loop input resistance of 100 ??. What is the closed-loop gain? if the basic amplifier is used to implement a unity-gain voltage buffer, what input resistance do you expect. Answer ALL parts of problem number 6, both parts A and B. thank you.
