Solve the following question given below:
Question: The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method. The activity of the sample is measured to be 0.521 times the Carbon-14 activity of living plants.
Part A: What is the age of the sample in years? (The half-life of the Carbon-14 isotope is 5730 years).
Please show all work so I can fully understand all concepts! Thank you.
