Two point charges, Q1 and Q2, are separated by a distance R. If the magnitudes of both charges are halved and their separation is also halved, what happens to the electrical force that each charge exerts on the other one?
 
  A) It increases by a factor of 16.
  B) It increases by a factor of 8.
  C) It increases by a factor of 2.
  D) It increases by a factor of 4.
  E) It remains the same.

Question 2

Two sources emit beams of light of wavelength 550 nm. The light from source A has an intensity of 10 W/m2, and the light from source B has an intensity of 20 W/m2. This is all we know about the two beams.
 
  Which of the following statements about these beams are correct? (There could be more than one correct choice.) A) Beam B carries twice as many photons per second as beam A.
  B) A photon in beam B has twice the energy of a photon in beam A.
  C) The frequency of the light in beam B is twice as great as the frequency of the light in beam A.
  D) A photon in beam B has the same energy as a photon in beam A.
  E) None of the above statements are true.

Hippocrates noted that blood separates into four differently colored liquids when removed from the body and examined: a pure red liquid mixed with white liquid material with a yellow-colored froth at the top and a black substance that settles underneath; he named these the four humors (for blood, phlegm, yellow bile, and black bile).
