Calculate the ground state energy of a harmonic oscillator with a classical frequency of 3.68  1015 Hz. (1 eV = 1.60  10-19 J, h = 1.055  10-34 J  s, h = 6.626  10-34 J  s)
 
  A) 7.62 eV
  B) 15.2 eV
  C) 11.4 eV
  D) 5.71 eV

Question 2

An 80-eV electron impinges upon a potential barrier 100 eV high and 0.20 nm thick.
 
  What is the probability the electron will tunnel through the barrier? (1 eV = 1.60  10-19 J,
  mproton = 1.67  10-27 kg, h = 1.055  10-34 J  s, h = 6.626  10-34 J  s)
  A) 0.011
  B) 1.1
  C) 0.11
  D) 1.1  10-4
  E) 7.7  10-10

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.
