Answer:
0.0001075
Step-by-step explanation:
The relation between halflife and rate at which it is decaying is given by
[tex]t_{\frac{1}{2} } =\dfrac{log2}{rate}[/tex]
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.
