Question

If the half-life of a radioactive substance is 2,800 years, then at what rate is it decaying?

Answer 1

Answer:

0.0001075

Step-by-step explanation:

The relation between halflife and rate at which it is decaying is given by

$t_{\frac{1}{2} } =\dfrac{log2}{rate}$

now in the above problem halflife is given as 2800 years substituting in the above equation we get the value of rate at which it is decaying to be rate=0.0001075.
