Question

which is the correct formula for calculating the age of a meteorite if using half - life?
o age of object = n + 1
o age of object = n × t
o age of object = \\( \frac { t } { n } \\)
o age of object = \\( \frac { t } { \frac { 1 } { 2 } } \\)

Explanation:

Step1: Recall half - life formula

The formula for calculating the age of an object using half - life is \(t = n\times t_{\frac{1}{2}}\), where \(n\) is the number of half - lives and \(t_{\frac{1}{2}}\) is the half - life of the radioactive substance.

Answer:

Age of object \(=n\times t_{\frac{1}{2}}\) (the second option).
