Exponential Change Practice Problems John McRaven 1) Do these quantities change exponentially? Explain. A) Bacteria Populations. B) E Th when water is heating up to some specific temperature. C) E Th Generated by a resistor. D) Money receiving compound interest. E) Number of 7B Text Books. F) Views of an Internet Meme (You do not need to view the video to understand the problem.) The actual quiz question will be similar to the above, but will likely require an understanding of heat flow, diffusion, or some other physics you have already learned. You should have gained a good enough conceptual understanding of the concepts to answer the questions that will be given. The general idea of these practice problems is to get an idea for what makes

Unformatted text preview: something change exponentially. 2) For the circuit given, assume that the capacitor begins in an uncharged state. At t=0, the switch is closed and current begins to flow: Figure 1: Circuit for Problem 2 A) Calculate the time constant for the circuit. 1 In the following, make sure you have plotted the graphs with the correct time constant. By ”magnitude of the,” I just mean make all the quantities positive on your plots. B) Plot the magnitude of the voltage across the capacitor. C) Plot the magnitude of the charge across the capacitor. D) Plot the magnitude of the voltage across the resistor. E) Plot the magnitude of the voltage across the battery. F) Plot the magnitude of the current. 2...
