If Planck's constant were smaller than it is, would this affect the sizes of atoms?
 
  A) No, because atomic orbits do not exhibit quantum uncertainties.
  B) No, because the sizes of atoms are determined by the electromagnetic force acting between the nucleus and the electrons and this force is not affected by quantum phenomena.
  C) Yes, atoms would then be larger than they are, because quantum uncertainties would be larger.
  D) Yes, atoms would then be larger than they are because the electromagnetic force would be weaker.
  E) Yes, atoms would then be smaller than they are, because quantum uncertainties would be smaller.

Question 2

The energy per unit volume in an electromagnetic wave is
 
  A) equally divided between the electric and magnetic fields.
  B) mostly in the electric field.
  C) mostly in the magnetic field.
  D) all in the electric field.
  E) all in the magnetic field.
