A nonrelativistic electron is accelerated from rest through a potential difference.
 
  After acceleration the electron has a de Broglie wavelength of 880 nm. What is the potential difference though which this electron was accelerated? (h = 6.626  10-34 J  s, e = - 1.60  10-19 C, mel = 9.11  10-31 kg)
  A) 2.5 V B) 2.2 V C) 1.9 V D) 1.7 V

Question 2

An electron is released from rest at a distance of 9.00 cm from a fixed proton.
 
  How fast will the electron be moving when it is 3.00 cm from the proton? (k = 1/40 = 8.99  109 N  m2/C2, e = 1.60  10-19 C, melectron = 9.11  10-31 kg, mproton = 1.67  10-27 kg)
  A) 75.0 m/s
  B) 106 m/s
  C) 130 m/s
  D) 1.06  103 m/s
  E) 4.64  105 m/s

A serious new warning has been established for pregnant women against taking ACE inhibitors during pregnancy. In the study, the risk of major birth defects in children whose mothers took ACE inhibitors during the first trimester was nearly three times higher than in children whose mothers didn't take ACE inhibitors. Physicians can prescribe alternative medications for pregnant women who have symptoms of high blood pressure.

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.
