The experimental observation(s) below that require(s) a quantum explanation for the photoelectric effect
 a. is that more photoelectrons are emitted when the light frequency increases.
  b. is that the maximum kinetic energy of the photoelectrons is related linearly to the frequency of the light.
  c. is that every metal surface has a work function, a minimum amount of energy needed to free electrons.
  d. is that the stopping potential measures the kinetic energy of the photoelectrons.
  e. are all of the above.

Question 2

Photoelectrons are ejected when monochromatic light shines on a freshly-prepared (oxide-free) sodium surface. In order to obtain the maximum increase in the number of electrons ejected per second, the experimenter needs to
 a. increase the frequency of the light.
  b. increase the intensity of the light.
  c. increase the area illuminated by the light.
  d. do all of the above. e. do only (b) and (c) above.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
