4) The tank shown has a bottom area A. A pressure source \hat{p}_s = p_s(t) + p_a is connected through a linear valve resistance, R?, to the bottom of the tank. Another linear valve resistance, R?, allows the fluid to exit the tank. (a) Assume R? = R? = R, and develop a model of h, where \hat{h} = h(t). What is the time constant of the model? (b) Right before both valves open simultaneously to allow fluid in and out of the tank, the height of the fluid in the tank is h?. If p?(t) = P_u s(t), determine the total response of the system for when both valves are open and fluid flows in and out of the tank, i.e., h(t). (20 points)

Question 9 of 18 (6 points) Question Attempt: 1 of t Time Remaining: 2:24:19 Stocks and Mutual Fund Ownership It has been found that 51.4% of U.S. households own stocks and mutual funds. A random sample of 300 heads of households indicated that 170 owned some type of stock. At what level of significance would you conclude that this was a significant difference? Use the P-value method. Assume the variable normally distributed. Use a graphing calculator Part 1 of 3 State the hypotheses and identify the claim with the correct hypothesis. $H_0$ (Choose one)? $H_1$ (Choose one)? This hypothesis test is a (Choose one) ? test. Part 2 of 3 Find the P-value. Round the answer to four decimal places. P-value = Part: 2 / 3 Part 3 of 3 At what level of significance is this a significant difference? Reject $H_0$ for any significance level (Choose one) ? than the P-value 0.0680 but fail to reject otherwise. Continue

9.10 The voltage applied to the circuit shown in Fig. 9.5 at t = 0 is 20 cos(800t + 25°) V. The circuit resistance is 80 ? and the initial current in the 75 mH inductor is zero. a) Find i(t) for t ? 0. b) Write the expressions for the transient and steady-state components of i(t). c) Find the numerical value of i after the switch has been closed for 1.875 ms. d) What are the maximum amplitude, frequency (in radians per second), and phase angle of the steady-state current? e) By how many degrees are the voltage and the steady-state current out of phase?

4. Computer experiment: denoising Write a MATLAB program to generate a noisy sinusoidal signal $x(t) = s(t) + n(t)$, where $s(t) = cos(2\pi f_m t)$, and $n(t)$ is additive white Gaussian noise. Use a band-pass filter to process this signal. Hand in your source code and plots that compare the original signal $x(t)$ with the filtered signal. You may let $f_m = 1000Hz$, and may use $t = 0 : 1/16000 : 0.06$ to simulate a sampling fre- quency of 16kHz. The noise $n(t)$ is simply an array of Gaussian random variables with zero- mean and certain variance. You can generate it by matlab command $randn(1, length) * v$, where $v$ is the standard deviation, and $v^2$ is in fact noise power. You may try different noise powers.

4) 10pts. Supongamos que tenemos dos esferas sólidas de masas m1 = 40 g y m2 = 80 g, suspendidas por su parte superior por hilos. Elevamos la masa m1 a una altura de 10cm hacia el lado izquierdo para luego ser soltada a una velocidad inicial de 0 m/s, esto producirá un choque elástico entre las masas. ¿Cuál será la altura que alcanzará la masa m2 luego del impacto?
