Short Answer

23.1 The Four Fundamental Forces

47.

  1. infinite
  2. the sum of the kinetic energies of the two particles
  3. zero
  4. the product of the kinetic energies of the two particles
52 .
Why do colliding beams result in the location of smaller particles?
  1. Colliding beams create energy, allowing more energy to be used to separate the colliding particles.
  2. Colliding beams lower the energy of the system, so it requires less energy to separate the colliding particles.
  3. Colliding beams reduce energy loss, so less energy is required to separate colliding particles.
  4. Colliding beams reduce energy loss, allowing more energy to be used to separate the colliding particles.

23.2 Quarks

53.

What two features of quarks determine the structure of a particle?

  1. the color and charge of individual quarks
  2. the color and size of individual quarks
  3. the charge and size of individual quarks
  4. the charge and mass of individual quarks
54.

What fundamental force does quantum chromodynamics describe?

  1. the weak nuclear force
  2. the strong nuclear force
  3. the electromagnetic force
  4. the gravitational force
55.

Is it possible for a baryon to be constructed of two quarks and an antiquark?

  1. Yes, the color of the three particles would be able to sum to white.
  2. No, the color of the three particles would not be able to sum to white.
56.

Can baryons be more massive than mesons?

  1. no
  2. yes
57 .
If antimatter exists, why is it so difficult to find?
  1. There is a smaller amount of antimatter than matter in the universe; antimatter is quickly annihilated by its matter analogue.
  2. There is a smaller amount of matter than antimatter in the universe; matter is annihilated by its antimatter analogue.
  3. There is a smaller amount of antimatter than matter in universe; antimatter and its matter analogue coexist.
  4. There is a smaller amount of matter than antimatter in the universe; matter and its antimatter analogue coexist.
58.

Does a neutron have an antimatter counterpart?

  1. No, the antineutron does not exist.
  2. Yes, the antineutron does exist.
59 .
How are the four fundamental forces incorporated into the Standard Model of the atom?
  1. The four fundamental forces are represented by their carrier particles, the electrons.
  2. The four fundamental forces are represented by their carrier particles, the gauge bosons.
  3. The four fundamental forces are represented by their carrier particles, the leptons.
  4. The four fundamental forces are represented by their carrier particles, the quarks.
60.

Which particles in the Standard Model account for the majority of matter with which we are familiar?

  1. particles in fourth column of the Standard Model
  2. particles in third column of the Standard Model
  3. particles in the second column of the Standard Model
  4. particles in the first column of the Standard Model
61 .
How can a particle gain mass by traveling through the Higgs field?
  1. The Higgs field slows down passing particles; the decrease in kinetic energy is transferred to the particle’s mass.
  2. The Higgs field accelerates passing particles; the decrease in kinetic energy is transferred to the particle’s mass.
  3. The Higgs field slows down passing particles; the increase in kinetic energy is transferred to the particle’s mass.
  4. The Higgs field accelerates passing particles; the increase in kinetic energy is transferred to the particle’s mass.
62 .
How does mass-energy conservation relate to the Higgs field?
  1. The increase in a particle’s energy when traveling through the Higgs field is countered by its increase in mass.
  2. The decrease in a particle’s kinetic energy when traveling through the Higgs field is countered by its increase in mass.
  3. The decrease in a particle’s energy when traveling through the Higgs field is countered by its decrease in mass.
  4. The increase in a particle’s energy when traveling through the Higgs field is countered by its decrease in mass.

23.3 The Unification of Forces

63 .
Why do scientists believe that the strong nuclear force and the electroweak force will combine under high energies?
  1. The electroweak force will have greater strength.
  2. The strong nuclear force and electroweak force will achieve the same strength.

  4. 10 − 38 seconds
66.

How does the search for the Grand Unified Theory help test the standard cosmological model?

  1. Scientists are increasing energy in the lab that models the energy in earlier, denser stages of the universe.
  2. Scientists are increasing energy in the lab that models the energy in earlier, less dense stages of the universe.
  3. Scientists are decreasing energy in the lab that models the energy in earlier, denser stages of the universe.
  4. Scientists are decreasing energy in the lab that models the energy in earlier, less dense stages of the universe.
67 .
Why does finding proof that protons do not decay not disprove all GUTs?
  1. Proton decay is not a premise of all GUTs, and current GUTs can be amended in response to new findings.
  2. Proton decay is a premise of all GUTs, but current GUTs can be amended in response to new findings.
68.

When accelerating elementary particles in a particle accelerator, they quickly achieve a speed approaching the speed of light. However, as time continues, the particles maintain this speed yet continue to increase their kinetic energy. How is this possible?

  1. The speed remains the same, but the masses of the particles increase.
  2. The speed remains the same, but the masses of the particles decrease.
  3. The speed remains the same, and the masses of the particles remain the same.
