Why doesn't the uncertainty principle affect our ability to follow the path of a baseball?
 
  A) The uncertainty principle applies only to subatomic particles.
  B) The uncertainties in all the individual atoms within the baseball cancel each other out.
  C) The uncertainties in the position and momentum of the baseball are so small in comparison to its size and total momentum that they are unnoticeable.
  D) The exclusion principle says that large objects are excluded from the consequences of the uncertainty principle.
  E) The uncertainty principle does not have anything to do with following the path of a particle or an object.

Answer to Question 1

C

Answer to Question 2

Every chemical element has a unique set of atomic energy levels and therefore a unique set of spectral lines. Thus, by identifying spectral lines, we can identify the elements that produced them.
