An ac source of maximum voltage V0 = 30 V is connected to a resistor R = 50 , an inductor L = 0.6 H, and a capacitor C = 20 F.
 
  What is the maximum charge on the capacitor when the frequency of the source is set to the resonance frequency of the circuit? A)
 
  1.0 mC
  B)
 
  0
  C)
 
  2.1 mC
  D)
 
  4.2 mC
  E)
 
  8.4 mC

Question 2

An unknown resistor is wired in series with an ammeter, and a voltmeter is placed in parallel across the resistor only. This network is then connected to a battery.
 
  If one computes the value of the resistance by dividing the voltmeter reading by the ammeter reading, the value obtained A)
 
  is less than the true resistance.
  B)
 
  is greater than the true resistance.
  C)
 
  is the true resistance.
  D)
 
  could be any of the given answers. It depends on other factors.

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).
