(a) A physicist connects a 7.50 V battery to the plates of a capacitor. After waiting a while, the capacitor reaches a maximum amount of 22.0 µC of stored charge. What is the value of the capacitance (in µF)? µF (b) The capacitor is disconnected from the battery, discharged, and then connected to a 10.0 V battery. Again, a long enough time is waited for the capacitor to fully charge. How much charge (in µC) is stored now? (Assume the capacitor can handle this new voltage without failing.) µC

Unit Problem: A sample of an unknown metal (c = 0.285 J/g*K) is heated to an initial temperature of 81.9 Â°C. It is added to a 28.49 g sample of water (c = 4.184 J/g*K), raising the temperature of the water from 24.7 Â°C to a final temperature of 28.6 Â°C. What is the mass of the metal, assuming no heat is lost to the calorimeter? A) Hypothesis: State your strategy for how to solve the problem in 2-4 sentences. Note that this should be targeted toward the specific example you are solving (i.e., do not just give a vague overview that could apply to solving any problem), but also should not go into the details or step-by-step instructions (save this for part D) B) Experimental Design: State three definitions and/or problem-solving rules that are necessary to complete the problem (1-2 sentences each). Ensure that you connect the rule/definition specifically with how it will be applied in the problem. See the Sample Quiz for examples. C) Solve: Complete the provided problem, showing all steps involved. This will often be best done by handwriting your work and including a picture of this work, rather than attempting to format within this Word document. This section should not include sentence explanations for the steps taken. D) Explanation: Explain, in 6-10 complete sentences and in your own words, all of the steps and considerations used to solve the problem above.
