Q126 / 180 · KCET 2019 · Physics

Which one of the following nuclei has shorter mean life?

A
\( \mathrm{C} \)
Correct answer
B
\( A \)
C
Same for al
D
\( B \)

Solution

(B)
Slope of the graph gives activity.
Higher activity shorter mean life and vice versa.

Hence, the correct answer is option: 'B'.
