Question

Which one of the following nuclei has shorter meant life?

 

Options

• C

• A

• Same for all

• B

Answer 1

A

Explanation:

The activity of such nuclei is determined by the slope of the supplied curves. In addition, the mean lifetime is inversely proportional to activity. As a result, the longer the activity, the shorter the substance's mean life. Nucleus A has the steepest slope. As a result, nucleus A has the shortest mean life of the three.
