A point charge +Q is located on the x axis at x = a, and a second point charge -Q is located on the x axis at x = -
 a. A Gaussian surface with radius r = 2a is centered at the origin. The flux through this Gaussian surface is
  a. zero because the negative flux over one hemisphere is equal to the positive flux over the other.
  b. greater than zero.
  c. zero because at every point on the surface the electric field has no component perpendicular to the surface. d. zero because the electric field is zero at every point on the surface. e. none of the above.

Question 2

A point charge is located at the origin. Centered along the x axis is a cylindrical closed surface of radius 10 cm with one end surface located at x = 2 m and the other end surface located at x = 4 m. If the magnitude of the electric flux through the surface at x = 2 m is 4 N  m2/C, what is the magnitude of the electric flux through the surface at x = 4 m?
 a. 1 N  m2/C
  b. 2 N  m2/C
  c. 4 N  m2/C
  d. 16 N  m2/C
  e. The correct value is not given.

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.
