Post Laboratory Questions: 1. For each of the following situations, describe what effect the following occurrences would have on your measurement of the solution concentration by titration. Would the "calculated" concentration come out too low, too high, or just right when compared to the "true" concentration? Explain briefly. a. You rinse the buret with water, instead of HCl before adding the HCl to the buret for titration. b. You don't notice the color change until several drops after the color change has occurred. c. The volumetric pipet fails to deliver the full 5.00 mL of your sample to the flask. d. In Step 4, you added 30 mL of water to titration flask instead of the 25 mL called for. e. You misread the buret and have actually delivered 0.05 mL less HCl than you recorded.

PROBLEMS, SECTION 7 Express the following integrals as B functions, and then, by (7.1), in terms of I functions. When possible, use I function formulas to write an exact answer in terms of π, √2, etc. Compare your answers with computer results and reconcile any discrepancies. 1. $\int_0^1 \frac{x^4}{\sqrt{1-x^2}} dx$ 2. $\int_0^{\pi/2} \sqrt{\sin^3 x \cos x} dx$ 3. $\int_0^1 \frac{dx}{\sqrt{1-x^3}}$

Problem #13: Consider the following initial value problem. y' + 6y = \begin{cases} 0 & t \le 2 \\ 9 & 2 \le t < 6 \\ 0 & 6 \le t < \infty \end{cases} y(0) = 10 (a) Find the Laplace transform of the right hand side of the above differential equation. (b) Let y(t) denote the solution to the above differential equation, and let Y(s) denote the Laplace transform of y(t). Find Y(s). (c) By taking the inverse Laplace transform of your answer to (b), the solution y(t) can be written in the form f(t) \mathcal{U}(t - 2) + g(t) \mathcal{U}(t - 6) + h(t). Enter the function f(t) into the answer box below. (d) Referring to part (c) above, enter the function g(t) into the answer box below. (e) Referring to part (c) above, enter the function h(t) into the answer box below.

Power Set write a program that reads a file that contain at most 10 values. If the file does not represents a set, the program will removes all duplicate. Afterwards, the program creates a new file and write all the subsets of the original file in he new file. Each subset should be on it's own line and enclosed in curly braces. For power Set can I have it written in python with no hard coded data and it must receive data from the user.
