The spacecraft is nearly ready for takeoff! The last task is to attach the start capacitor to the ship in a simple RC-circuit. Your computer warns you that some adjustments may need to be made if the heat generated in the resistor over the initial time interval is higher than a given threshold. Your computer is able to provide the following information, along with a note that the units are already accounted for in the equations: Heat Generated in Resistor over the first 3 seconds: $Q = \frac{V_b^2}{R} \int_0^3 e^{-2t/(RC)} dt$ joules Voltage of the Battery: $V_b = 5$ volts Resistance: $R = 5$ ohms Capacitance: $C = \frac{1}{5}$ farads Maximum Heat Allowed in Resistor: $Q_{max} = 2.5$ joules Is the heat generated in the resistor over the first 3 seconds below the maximum allowable threshold? Yes No What is the difference between the maximum threshold (provided above by your computer) and the amount of heat generated in the resistor (that you calculated)? Provide a positive value up to three decimal places. 2.594 joules

Your parents invited your crazy uncle over for holiday dinner. When you mention your BIOL&100 course, that causes your uncle to start talking about the biology of vaccines, specifically the COVID-19 mRNA vaccine. Your uncle proudly says he did not get a vaccination because it "alters your DNA." Using your knowledge of the Central Dogma of Biology (transcription and translation) from several weeks ago, and what you learned about mRNA vaccines, briefly explain to your uncle (in 2-3 sentences) how his conspiracy theory is not biologically possible.
