An electron follows a circular path (radius = 15 cm) in a uniform magnetic field (magnitude = 3.0 G). What is the period of this motion?
 a. 0.12 ms
  b. 1.2 ms
  c. 0.18 ms
  d. 1.8 ms
  e. 1.8 ms

Question 2

An electron moves in a region where the magnetic field is uniform, has a magnitude of 60 mT, and points in the positive x direction. At t = 0 the electron has a velocity that has an x component of 30 km/s, a y component of 40 km/s, and a z component of zero. What is the radius of the resulting helical path?
 a. 4.7 mm
  b. 18 mm
  c. 3.8 mm
  d. 2.8 mm
  e. 5.7 mm

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
