The nucleus of an atom contains positively charged particles, called protons, and neutral particles, called neutrons.
How is the nucleus of an atom held together?
A.
Electric forces exist between the protons and neutrons in a nucleus, and the particles are attracted to one another by these electric forces.
B.
A strong force exists between the particles in a nucleus, and this force is usually stronger than the electric forces that would pull them apart.
C.
A strong force exists between the particles of the nucleus, but this force is always much weaker than the electric forces that would pull them apart.
D.
Electric forces exist between the protons of the nucleus, and the protons are attracted to one another by these electric forces.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
