If n_(t) number of radioatoms are present at time t, the following exp – InterviewSolution

1.	If n_(t) number of radioatoms are present at time t, the following expression will be a constant
Answer» `n_(t)//t` ln `n_(t)//t` `d ln n_(t)//DT` `t.n_(t)` Solution :`- (dn_(t))/(dt) = LAMDA n_(t) RARR - (1)/(n_(1)) (dn_(t))/(dt) = lamda` `rArr (d)/(dt) (ln, n_(t)) = - lamda`, a CONSTANT
