Case History A 2-month-old boy is admitted to the hospital with an overnight history of coughing fits. These began with frequent incidents of rapid coughing, that would progress to the baby turning red and gasping for air. The mother indicated that he also had two episodes of vomiting. The baby was found to have an increased breathing rate, and his chest x-ray showed no evidence of pneumonia. Blood work showed an abnormally large percentage of lymphocytes (70%). A nasopharyngeal swab was cultured. Gram stain of colonies revealed minute Gram negative coccobacilli. The culture confirms PCR rapid test results. Gram stain of coccobacilli from nasopharyngeal sample 1. Which is the main organ system affected? [Select]

2. You decide to build an RC circuit out of scrap. To build the capacitor you use two square sheets of aluminum foil 10 cm on a side with cellophane sandwiched between them (e.g., Saran Wrap). Your cellophane has a dielectric constant $K = 3.5$ and a thickness 0.0125 mm. You also connect the plates together with 25 m of 30 gauge (0.255 mm diameter) copper wire (of resistivity $\rho = 1.72 \times 10^{-8} \Omega \text{m}$). Find the time constant $RC$ that describes how a charge on the capacitor would grow with time. (You may ignore resistance within the aluminum foil. The vacuum permittivity of free space is $\epsilon_0 = 8.854 \times 10^{-12} \frac{C^2}{N m^2}$.) If the battery in the circuit has 9 V, find the charge on the capacitor after $8.0 \times 10^{-8}$ s.
