2. You are grading student answers on a quiz. Of the student responses below, who would get full credit? For students who would not get full credit, indicate what is wrong with their answer. If you think a student should receive full credit please write "this answer is correct" [Each student phrase is worth 1 point, 5 points total] Student A: PCR is similar to DNA replication in that it also requires high temperatures, a primer pair, and ligase. Student B: PCR is similar to DNA replication in that it requires a 3' -OH group, dNTPs, and DNA polymerase Student C: PCR is similar to DNA replication in that it requires ligase, helicase, and topoisomerase to proceed Student D: PCR is different from DNA replication because it requires high temperatures, dNTPs, and Okazaki fragments Student E: PCR is different from DNA replication because it requires high temperatures, a primer pair, and results in exponential amplification.

Part C Enter a chemical equation for HF(aq) showing how it is an acid according to the Arrhenius definition. Express your answer as a chemical equation including phases. View Available Hint(s) HF(aq) $\rightarrow$ H$^{+}$ (aq) + F$^{-}$ (aq) A chemical reaction does not occur for this question. Submit Previous Answers Incorrect; Try Again; 2 attempts remaining Notice that HF is a weak acid that partially ionizes when dissolved in water. Thus, an equilibrium arrow ($\rightleftharpoons$) is needed. You may want to review Hint 1. How to approach the problem.

5. [1.34/2 Points] A sinusoidal voltage $\Delta V = 37.5 \sin(100t)$, where $\Delta V$ is in volts and $t$ is in seconds, is applied to a series RLC circuit with $L = 180 \, mH$, $C = 99.0 \, \mu F$, and $R = 54.0 \, \Omega$. (a) What is the impedance (in $\Omega$) of the circuit? 99.0 (b) What is the maximum current (in A)? 0.379 (c) Determine the numerical value for $\omega$ (in rad/s) in the equation $i = I_{max} \sin(\omega t - \phi)$. 100 (d) Determine the numerical value for $\phi$ (in rad) in the equation $i = I_{max} \sin(\omega t - \phi)$. 0.99 Does the current lead or lag the voltage in this circuit? rad (e) What If? For what value of the inductance (in H) in the circuit would the current lag the voltage by the same angle $\phi$ as that found in part (d)? 0.180 (f) What would be the maximum current (in A) in the circuit in this case? 0.379
