A particle with charge -40.0 nC is on the x axis at the point with coordinate x = 0. A second particle, with charge -20.0 nC, is on the x axis at x = 0.500 m. Is there a point at a finite distance where the electric potential is zero?
  1.Yes; it is to the left of x = 0.
  2.Yes; it is between x = 0 and x = 0.500 m.
  3.Yes; it is to the right of x = 0.500 m.
  4.No.

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).

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
