3 The circuit illustrated in Figure 2 is driven by an EMF, V = $V_0e^{i\omega t}$ X L R C A L B L Figure 2 At time $t_1$, the switch is closed on A. 3.1 Calculate the complex impedance $Z_{xy}$ of the circuit. [4] 3.2 What is the non-zero frequency $\omega_0$ that maximizes the average power dissipated in the resistor R? [4] 3.3 For $\omega = \omega_0$, what is the average power dissipated in the resistor R? [4] 3.4 Calculate $I_R$, the current flowing through the resistor R when $\omega = \omega_1 = 1/\sqrt{2LC}$ What is the phase between $I_R$ and V when $\omega = \omega_1 = 1/\sqrt{2LC}$? Is $I_R$ leading or lagging V? [4] At time $t_2$, the switch is closed on B. 3.5 What is the complex impedance $Z_{xy}$ of the circuit now? [4] 3.6 How does $V_R$ depend on the frequency $\omega$? Draw a graph. [3]

Which of the following is correct about the optimum temperature of a reaction? As temperature increases toward the optimum, this changes the potential energy level of the molecules so that they can better react. An increase in temperature toward the optimum causes an increase in the activation energy of a reaction, which allows the reaction to proceed faster. The optimum temperature is the exact temperature at which covalent bonds of the reactant molecules are able to break and temperatures outside the optimum are unable to achieve a reaction. As temperature increases toward the optimum, an increased movement of molecules increases the likelihood that the molecules will collide and react with each other. The optimum temperature is when the enzyme becomes unfolded, which allows the enzyme to catalyze the reaction. Which of the following is correct about the optimum temperature of a reaction?
