1. A unit step of heat is applied at the left boundary of an insulated rod. The response is measured at the center point of the rod and it is described by the function s(t) = 1 - e^{-2t} Then an arbitrary input is applied at the same (left) boundary of the rod defined by the function g(t) = \sin(2\pi(0.5)t) a). Compute the response of the system to g(t). Your answer should include well-labeled plots of all the relevant functions. b). Instead of a unit step, a unit pulse is applied. What is the unit pulse response? c). Compute the response of the system to the same g(t). d). What is the Green's function for this system?

Sampling (Ch 8): Choose a random sample of size 16 (n=16) from your population (your first series), using an appropriate sampling method. Show/explain how you chose the sample. You will be using this sample in questions 5-8. Notice that in the help videos, question 4 has parts a and b. Part a has since been dropped, this corresponds to part b. 5. Estimation and Confidence Intervals with known Ïƒ (Ch 9): (Treating your first series as a population as you did above), assume you don't know the mean of the population from which your sample came, but you know Ïƒ. (Note that, in the help video for this question, there was an alternative way to compute Ïƒ by assuming the series is a sample. This semester, you do not need to do that, you can assume Ïƒ is just the standard deviation of your series which you are assuming is a "population"). Also assume you do not have any other information about the population. Use your random sample of size 16 above as your sample from which to estimate the population mean. Compute and clearly indicate the following: a. The point estimate of the population mean. b. The standard error (of the mean). c. The critical z-value for 95% confidence level. d. The margin of error. e. Lower and upper confidence limits (LCL, UCL). f. The confidence interval for the population mean (Î¼) in the format LCL - UCL.

Probleem 1 / Problem 1 Consider the following problem from a previous version of the text book: xy 3.23 The moment of inertia $I_x$, $I_y$, and the product of inertia $I_{xy}$ of the cross-sectional area shown in the figure are: $I_x = 1.928 \times 10^{-6} m^4$, $I_y = 1.539 \times 10^{-6} m^4$, and $I_{xy} = 0.518 \times 10^{-6} m^4$ The principal moments of inertia are the eigenvalues of the matrix $\begin{bmatrix} 1.928 & 0.518\\ 0.518 & 1.539 \end{bmatrix} \times 10^{-6}$, and the principal axes are in the direction of the eigenvectors. 80 mm 100 mm 16 mm 0 26 mm 12 mm 1 Vi. (a) Use the eig command to compute the prin- cipal moments of inertia as well as the direc- tions of the principal axes. (The principal axes are the two axes along which one can spin the object without wobbling.) (b) Plot the principal axes in the plane. Use axis equal, otherwise the axes may not be perpendicular to each other. (Perpendic- ular axes is a consequence of the fact that the eigenvectors of symmetric matrices can always be chosen to be orthogonal.) Challenge: Plot the object and the princi- pal axes on the same figure. No marks, but good practice for you.

The gas is held at constant volume V and temperature T. m d 3m a) Find the partition function of a single molecule, assuming that T >> \hbar²/mkd². b) Calculate the internal energy E and specific heat $C_V$ of this gas at high temperature. Show that your result is consistent with the equipartition theorem.
