The first laboratory discovery of nuclear fission occurred
 
  A) in Marie Curie's lab in the early 1900s.
  B) in London in 1930.
  C) in Germany in 1938.
  D) in New Mexico in 1944
  E) in the United States in 1940.

Question 2

Earth exerts a force on the Moon. These two bodies make up
 
  A) one interaction.
  B) two interactions.
  C) multiple interactions.

Question 3

A parallel-plate capacitor, with air between the plates, is connected across a voltage source. This source establishes a potential difference between the plates by placing charge of magnitude 4.15  10-6 C on each plate.
 
  The space between the plates is then filled with a dielectric material, with a dielectric constant of 7.74. What must the magnitude of the charge on each capacitor plate now be, to produce the same potential difference between the plates as before?
