Question 38 POST_UTME_BSU • 2017 • PHYSICS • objective

A radioactive sample decays according to the equation $N(t) = N_0 e^{-lambda t}$, where $N(t)$ is the number of nuclei remaining at time $t$, $N_0$ is the initial number of nuclei, and $lambda$ is the decay cons\tant. If the half-life of the sample is $10,mathrm{years}$, calculate the decay cons\tant $lambda$.

Correct Answer A. $ lambda = \frac{ln 2}{10} $

B. $ lambda = \frac{10}{ln 2} $

C. $ lambda = \frac{2}{10} $

D. $ lambda = \frac{10}{2} $

Correct Answer

Correct Option:

$ lambda = \frac{ln 2}{10} $
