Answer on Electric Circuits Question for moses

Question #35837
The half-life of a certain radioactive isotope is 32 hours. What fraction of the sample would remain after 16 huors? a. 0.50 b. 0.25 c. 0.62 d. 0.71
Expert's answer
The formula for radioactive decay is

N=N0 * (1/2)^(t/tau)

where N0 is initial quantity of isotope and tau is half-life.
so we find
N/N0 = (1/2)^(t/tau) = (1/2)^(1/2) = 0.71

Answer is d. 0.71
