23.1 The Four Fundamental Forces
If the strong attractive force is the greatest of the four fundamental forces, are all masses fated to combine together at some point in the future? Explain.
- No, the strong attractive force acts only at incredibly small distances. As a result, only masses close enough to be within its range will combine.
- No, the strong attractive force acts only at large distances. As a result, only masses far enough apart will combine.
- Yes, the strong attractive force acts at any distance. As a result, all masses are fated to combine together at some point in the future.
- Yes, the strong attractive force acts at large distances. As a result, all masses are fated tocombine together at some point in the future.
23.2 Quarks
In this image, how does the emission of the gluon cause the down quark to change from a red color to a green color?
- The emitted red gluon is made up of a green and a red color. As a result, the down quark changes from a red color to a green color.
- The emitted red gluon is made up of an anti-green and an anti-red color. As a result, the down quark changes from a red color to a green color.
- The emitted red gluon is made up of a green and an anti-red color. As a result, the down quark changes from a red color to a green color.
- The emitted red gluon is made up of an anti-green and a red color. As a result, the down quark changes from a red color to a green color.
Neutrinos are much more difficult for scientists to find when compared to other hadrons and leptons. Why is this?
- Neutrinos are hadrons, and they lack charge.
- Neutrinos are not hadrons, and they lack charge.
- Neutrinos are hadrons, and they have positive charge.
- Neutrinos are not hadrons, and they have a positive charge.
The term force carrier particle is shorthand for the scientific term vector gauge boson. From that perspective, can the Higgs boson truly be considered a force carrier particle?
- No, the mass quality provided by the Higgs boson is a scalar quantity.
- Yes, the mass quality provided by the Higgs boson results in a change of particle’s direction.
23.3 The Unification of Forces
If a Grand Unified Theory is proven and the four forces are unified, it will still be correct to say that the orbit of the Moon is determined by the gravitational force. Explain why.
- Gravity will not be a property of the unified force.
- Gravity will be one property of the unified force.
- Apart from gravity, no other force depends on the mass of the object.
- Apart from gravity, no other force can make an object move in a fixed orbit.
As the universe expanded and temperatures dropped, the strong nuclear force separated from the electroweak force. Is it likely that under cooler conditions, the force of electricity will separate from the force of magnetism?
- No, the electric force relies on the magnetic force and vice versa.
- Yes, the electric and magnetic forces can be separated from each other.
