A long wire along the x axis is carrying a current increasing at a constant rate in the +x direction. A rectangular coil lies in the x-y plane in the 4th quadrant. In which direction is the induced magnetic field at the center of the rectangular coil?
 a. in the z direction
  b. There is no direction; the induced current in the coil is zero since the x axis and the coil are in the same plane.
  c. in the +z direction
  d. No direction can be found since the orientation of the rectangular coil is not given.

Question 2

 a. is longer than Bar Two.
  b. has a greater cross-sectional area than Bar Two.
  c. has a greater elastic limit than Bar Two.
  d. is made of material that is different from Bar Two.

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.
