A 0.120-pF parallel-plate capacitor is charged to a potential difference of 10.0 V and then disconnected from the battery. A cosmic ray burst creates 1.00  106 electrons and 1.00  106 positive charges between the plates. If the charges do not recombine, but reach the oppositely charged plates, by how much is the potential difference between the capacitor plates reduced?
 a. 1.33 V
  b. 7.34 V
  c. 8.67 V
  d. 1,330 V
  e. 8,670 V

Question 2

An initially uncharged parallel plate capacitor of capacitance C is charged to potential V by a battery. The battery is then disconnected. Which statement is correct?
 a. There is no charge on either plate of the capacitor.
  b. The capacitor can be discharged by grounding any one of its two plates.
  c. Charge is distributed evenly over both the inner and outer surfaces of the plates.
  d. The magnitude of the electric field outside the space between the plates is approximately zero.
  e. The capacitance increases when the distance between the plates increases.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
