I already answered a few of them, but I just wanted to make sure they were right. Please help with any of them that you know, if you do not know that answer, please do not guess, I really need a good grade! =]
Question 2 (Multiple Choice Worth 2 points)
Which statement describes the relationship between gravitational force and strong nuclear force?
Strong nuclear force is the stronger force; it is related to weight.
Gravity is the weaker force; it is related to mass.
Strong nuclear force is the weaker force; it is related to size.
Gravity is the stronger force; it is not related to weight.
Question 5 (Multiple Choice Worth 2 points)
Electromagnetic force is present when electromagnetic fields
become charged as they lose electrons.
become stable as they come in contact with other forces.
interact with charged particles.
gain energy from other forces.
Question 11 (Multiple Choice Worth 2 points)
Which statement best describes the difference between strong nuclear forces and weak nuclear forces?
Weak nuclear forces hold protons and neutrons together; strong nuclear forces hold electrons in their shells.
Strong nuclear forces are responsible for holding electrons in bonds; weak nuclear forces are involved when the bonds break.
Weak nuclear forces hold the atoms' nucleus together; strong nuclear forces tear them apart.
Strong nuclear forces are responsible for holding together the nucleus of an atom; weak nuclear forces are involved when certain types of atoms break down.

Question 18 (Multiple Choice Worth 2 points)
Which statement best describes the relationship between forces?
Magnetic and electrical forces are the most alike because they are both caused by positive and negative charges.
Gravitational and magnetic forces are the most alike because they are both types of charges that occur in nature.
Nuclear and magnetic forces are the most alike because they are both related to mass and weight.
Strong nuclear force is most like electric because they are both related to distance.
