Chapter 20, Problem 24R

To determine

The strong force and radioactivity are to be compared and contrasted.

Answer to Problem 24R

Strong forces are the forces that causes the protons and the neutrons to be attracted towards each other.

Radioactivity is process of emission of invisible rays from a substance.

Explanation of Solution

Compare:

Radioactivity is the process of releasing of energy. Emission of proton and neutron when strong forces are not able to hold the nucleus.

Contrast:

Strong force is based upon size of nucleus. radioactivity depends upon nuclear decay.

Conclusion:

Strong force is one of the four basis force in nature.

Radioactivity is process of emission of alpha beta and gamma particles.
