The half life for the decay of carbon-14 is 5.73 x 10 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 1.0 x 10 bq. the activity in a similar-sized sample of fresh wood is measured to be 4.3 x 10 bq. calculate the age of the artifact. round your answer to 2 significant digits. 1 years
