The effective half-life T_1/2 of the nuclei is :ANone of the aboveBT1/2=T1/2(1)+T1/2(2){T_{1/2}} = T_{1/2}^{(1)} + T_{1/2}^{(2)}T1/2=T1/2(1)+T1/2(2)CT1/2=T1/2(1)T1/2(2)T1/2(1)+T1/2(2){T_{1/2}} = {{T_{1/2}^{(1)}T_{1/2}^{(2)}} \over {T_{1/2}^{(1)} + T_{1/2}^{(2)}}}T1/2=T1/2(1)+T1/2(2)T1/2(1)T1/2(2)DT1/2=T1/2(1)+T1/2(2)T1/2(1)−T1/2(2){T_{1/2}} = {{T_{1/2}^{(1)} + T_{1/2}^{(2)}} \over {T_{1/2}^{(1)} - T_{1/2}^{(2)}}}T1/2=T1/2(1)−T1/2(2)T1/2(1)+T1/2(2)Check answerSkip
