The rate law for the reaction is below: rate = k[IO$_3$]$^p$[SO$_3^{-2}$]$^q$ What is the meaning of the coefficients p and q in the reaction? They represent the charge on the ions. They represent the rate each compound is used. They represent the order of reaction with respect to each reactant. They represent the coefficients in the balanced equation.

You, a researcher, administer a stress-relieving intervention to 25 participants. You use a hypothesis test to evaluate the effect of the intervention and get a z-score of 1.77. If you are using a two-tailed test, what conclusion should you make? ? Reject the null hypothesis using either an alpha of .01 or .05 ? Fail to reject the null hypothesis using either an alpha of .01 or .05 ? There is not enough information to make a conclusion ? Reject the null hypothesis with an alpha of .05 but not .01

35. [-/3 Points] DETAILS SERESSEN1 21.P.022. A coil of resistance 35.0 $\Omega$ and inductance 21.3 H is in series with a capacitor and a 200-V (rms), 100-Hz source. The rms current in the circuit is 4.00 A. (a) Calculate the capacitance in the circuit. (List the lowest value first. If the values are too close to differentiate, just list the common value twice.) nF nF or (b) What is $\Delta V_{rms}$ across the coil? ($\Delta V_{rms}$) coil = kV

(Power Factor Correction) In an industrial plant with a large number of induction motors, during certain loading conditions, the inductor motors have a large reactive component and the power factor is low. Capacitor banks and synchronous motors are two commonly used methods for power factor correction. a) Capacitor based power factor correction: A capacitor bank is connected in parallel with the induction motor in problem 2. Calculate the capacitance value needed to bring the total power factor to unity. (1 point) b) Synchronous motors can also be used for power factor correction. A synchronous motor with 5 kW power input is connected in parallel with the induction motor, what power factor should the synchronous motor operate at to bring the total power factor to unity? (1 point) c) Both capacitors and synchronous motors can achieve the goal of power factor correction. Discuss the implications of a low power factor. Compare these two methods and discuss the advantages and disadvantages of each method with considerations of social, environmental, economic factors. (2 points) d) For a MW level large industrial plant located in rural area, its low power factor has been causing high utility bills. This specific plant has enough budget to install a power factor correction system and they are looking into a solution with long service life and flexible power factor control, which solution should they choose, capacitor banks or synchronous motor? (1 point)

4. (20 points) A 3-node, 2-element linear elastic rod is shown below for which the modulus is constant E, and the cross-sectional area varies as $A(x) = 3 + e^x$, x being the global coordinate. $A(x) = 3 + e^x$ As seen in the recent homework, the strong form for this problem is $\frac{d}{dx}(EA(x)\frac{du}{dx}) = 0$ For element 2 in the figure above, derive the stiffness matrix $[K^e]$
