The half life for the decay of carbon-14 is 5.73 × 10³ years. Suppose the activity due to the radioactive decay of the carbon-14 in a tiny sample of an artifact made of wood from an archeological dig is measured to be 4.7 x 10 Bq. The activity in a similar-sized sample of fresh wood is measured to be 7.0 x 10 Bq. Calculate the age of the artifact. Round your answer to 2 significant digits.
