A sample has a C614 activity of 0.0089 Bq per gram of carbon. (a) Find the age of the sample, assuming that the activity per gram of carbon in a living organism has been constant at a value of 0.23 Bq. (b) Evidence suggests that the value of 0.23 Bq might have been as much as 44% larger. Repeat part (a), taking into account this 44% increase.
