If a Cu2+ ion that is initially at rest accelerates through a potential difference of 12 V without friction, how much kinetic energy will it gain? (e = 1.60  10-19 C)
 
  A) 3.0 eV.
  B) 6.0 eV.
  C) 12 eV.
  D) 24 eV.

Question 2

An object floats with half its volume beneath the surface of the water. The weight (force that Earth exerts in it) of the displaced water is 2000 N.
 
  What is the weight (force that Earth exerts on it) of the object? The density of water is 1000 kg/m3. A) 1000 N
  B) 2000 N
  C) 4000 N
  D) It cannot be determined because we do not know the volume of the object.
