In the circuit in (Figure 1), $C = 250 mF$, $L = 0.4 H$, $V_o = 0 V$, and $I_o = -3 A$. Assume that resistor $R$ is removed from the circuit. Choose the correct expression for $v(t)$ for $t \ge 0$. $v(t) = -2.79 \sin(3.16t) V$ $v(t) = 1.49 \sin(3.16t) V$ $v(t) = 2.79 \sin(3.16t) V$ $v(t) = -1.49 \sin(3.16t) V$ $v(t) = 3.79 \sin(3.16t) V$ $v(t) = -3.79 \sin(3.16t) V$ Calculate the frequency of $v(t)$ in rad/s. Express your answer in radians per second to three significant figures. Calculate the maximum amplitude of $v(t)$ in volts. Express your answer in volts to three significant figures.

Let X be a random variable. Suppose that, given 9, X has the conditional distribution w.p.1-0 w.p.o Suppose we have the following prior for 0: 0 is uniformly distributed in the set {0, ,1}. Compute the posterior distribution of given X=0, that is,P=X =0), and the posterior distribution of given X = 1, that is, P( =X = 1).

Using the color lena image 1- Add gaussian type noise to this image. 2- Pass through 5x5,7x7, 9x9, 11x11, 15x15 average and median filters. 3- Graph the PSNR values obtained for the average and median filters. (On one graph, one series can be arranged to show PSNR values for the average filter, and the other series to show PSNR values for the median filter) 4- Add salt and pepper type noise to this image. 5- Perform steps 2 and 3 for this noise type. 6- Interpret the results. Develop the codes that will perform the above-mentioned image processing steps with MATLAB.

5. Barnard's star is fourth closest known star to our Sun, and has the fastest motion across the sky of any star (10.34 arcsec/year). It has a radial speed of -108 km/s and a parallax of 546 milliarcsec. (a) What is the distance to Barnard's star in parsec? (b) What is its tangential speed in km/s? (c) What is its space velocity (in km/s) and what angle does the space velocity make with our line of sight? (d) At its closest approach to Earth, how distant in parsecs will it be? Compare this to the distance to Alpha Centauri. (e) Given its current apparent visual magnitude of 9.54, what will be its apparent visual magnitude at closest approach? How much brighter in terms of observed flux?
