i am sorry माझी च गलती झाली येथी येऊन

Answer 2

Concept Introduction:-

It could take the shape of a word or a numerical representation of a quantity's arithmetic value.

Given Information:-

We have been given that Radioactive sample of Img reduce to $0.01$ mg in

$100$ mint

To Find:-

We have to find that its decay constant.

Solution:-

According to the problem

$A_0=1mg, A_t=0.01mg,t=100min$

λ$=\frac{2303}{t}log \frac{A_0}{A_t}\\=\frac{2303}{100}log \frac{1}{0.01}\\=0.046min^{-1}$

Final Answer:-

The correct answer is $0.046min^{-1}$.
