Which of the following is the correct definition for baryons?

• Composite subatomic particles made up of three quarks.

• Subatomic particles composed of one quark and one antiquark.

• Subatomic particles that are a type of hadron and are governed by the strong nuclear force.

• Particles that are governed by the weak nuclear force and, since they have charge, are also influenced by electromagnetism.

• Composite subatomic particles made up of three quarks.
• Subatomic particles composed of one quark and one antiquark.
• Subatomic particles that constitute hadrons and are governed by the strong nuclear force.
• Particles that are governed by the weak nuclear force and, since they have charge, are also influenced by electromagnetism.

If you punch a wall, why does your hand hurt?

• The wall is solid.
• You're weak.
• The wall exerts a force back on your hand.
