Answer:
Age of the ancient wood object is 11460 years.
Explanation:
We know that half-life for carbon-14 is 5730 years. That means the activity of the sample will decrease to half every 5730 years.
Now we construct the following table:
activity (counts/min) age of the wooden object
40 0
20 5730
10 11460
