[Ques. 2] Which of the following particles are leptons?
 a. Mesons and baryons.
  b. Mesons and neutrinos.
  c. Electrons and neutrinos.
  d. Muons and baryons.
  e. Tau and mesons.



[Ques. 3] You are holding your physics book, pushing upwards on it with the palm of your hand. The reaction to the weight of the book is the force on __________ by __________.
 Fill in the blank(s) with correct word



[Ques. 4] Which of the following particles participate in the strong interaction?
 a. Mesons and leptons.
  b. Mesons and neutrinos.
  c. Neutrinos and leptons.
  d. Mesons and baryons.
  e. Baryons and leptons.



[Ques. 5] You are holding your physics book, pushing upwards on it with the palm of your hand. The reaction to this force is the force on __________ by __________.
 Fill in the blank(s) with correct word



[Ques. 6] How are the particles in the elementary particle zoo classified in order to relate them effectively?
 a. By particle size.
  b. By charge.
  c. By which force the particles participate in.
  d. By mass.
  e. By location.



[Ques. 7] You can tell whether a projectile is going upwards or downwards from the sign of __________.
 Fill in the blank(s) with correct word



[Ques. 8] Which of the following particles has not yet been detected (even though most scientists consider its existence to be likely)?
 a. The pion.
  b. The muon.
  c. The graviton.
  d. Intermediate vector bosons.
  e. The positron.



[Ques. 9] You throw a ball straight up. As the ball is going up, the direction of the velocity and acceleration point __________.
 Fill in the blank(s) with correct word



[Ques. 10] Why does the nuclear force have a short range?
 a. Because the exchanged particles have nonzero mass, and thus limited time before they can complete the exchange.
  b. Because the low mass of the exchange particles means their exchange is effective only over short distances.
  c. Because the exchange particles have zero mass and thus limited time before they can complete the exchange.
  d. Because the exchanged particles must travel long distances to complete the exchange.
  e. Because it is the weakest of the four forces.
