Suppose that Al the physicist observes a single radioactive nucleus. The length of time until that particular nucleus decays is
 
  A) unpredictable because of the practical difficulties of obtaining all the information needed to make the prediction.
  B) unpredictable because of fundamental uncertainties arising from quantum physics
  C) predictable from the known half-life of the nucleus.
  D) unpredictable because of fundamental uncertainties arising from Newtonian physics.
  E) predictable, provided Al knows the precise nuclear state of this nucleus.

Question 2

Four equal +6.00-C point charges are placed at the corners of a square 2.00 m on each side. (k = 1/40 = 8.99  109 N  m2/C2)
 
  (a) What is the electric potential (relative to infinity) due to these charges at the center of this square?
  (b) What is the magnitude of the electric field due to these charges at the center of the square?
