A 2.0-cm length of wire centered on the origin carries a 20-A current directed in the positive y direction. Determine the magnetic field at the point x = 5.0 m on the x-axis.
 a. 1.6 nT in the negative z direction
  b. 1.6 nT in the positive z direction
  c. 2.4 nT in the negative z direction
  d. 2.4 nT in the negative z direction
  e. None of the above

Question 2

An unusual lightning strike has a vertical portion with a current of -400 A downwards. The Earth's magnetic field at that location is parallel to the ground and has a magnitude of 30 mT. In N, the force exerted by the Earth's magnetic field on the 25 m-long current is
 a. 0.
  b. 0.012 N, East.
  c. 0.012 N, West.
  d. 0.30 N, West.
  e. 300 N, East.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
