<span>Some of the things that would make the experiment invalid would be, if there was a variation in the behavior of the class with respect to food - for example, if some people ate their breakfast earlier than the others. This then would mean that some students would have already digested their breakfast during the morning classes and the others would still be digesting. </span>

Yanni made a chart to compare the strong and weak forces. Which best describes Yanni’s error? Only the weak force is active in t
cluponka [151]

Answer: Option (d) is the correct answer.

Explanation:

Nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons have no charge. So, due to the like charges of protons there occurs electrostatic force of repulsion inside the nucleus of the atom.

But due to similar number of neutrons and protons a force that is able to bind both of them together is known as strong nuclear binding energy.

This force is strong enough that it is able to overcome electrostatic force of repulsion. But when there is great difference in the number of protons and neutrons then binding force is not strong enough.

Hence, the atom becomes unstable and undergoes radioactive decay. So, this means weak forces are responsible for radioactive decay.

Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay.
