How much work is needed to carry an electron from the positive terminal to the negative terminal of a 9.0-V battery. (e = 1.60  10-19 C , melectron = 9.11  10-31 kg)
 
  A) 1.6  10-19 J
  B) 17  10-19 J
  C) 14.4  10-19 J/C
  D) 9.0 J
  E) 14.4  10-19 J

Question 2

A hydrogen atom is excited to the n = 10 stated. It then decays to the n = 4 state by emitting a photon which is detected in a photographic plate. What is the frequency of the detected photon? The lowest level energy state of hydrogen is -13.6 eV.
 
  (h = 6.626  10-34 J  s, 1 eV = 1.60  10-19 J)
  A) 4.05  1014 Hz
  B) 1.73  1014 Hz
