Answer is:
78
Explanation:
Use N1/N0=(1/2)10/T and X/100 = (1/2)24/T
Answer is:
20 minutes
Explanation:
Let N0 be the number of nuclei at the beginning. Number of undecayed nuclei after 33% decay = 0.67N0 Number of undecayed nuclei after 67% decay = 0.33N0 Also 0.33N0 >> 0.67N0 / 2. And in one half-life the number of undecayed nuclei becomes half.
Answer is:
15 sec
Explanation:
use N/No=(1/2)1/T1/2 T1/2=t2 - t1 t(mean)=T1/2/0.693
