Explain carbon-14 which is present in all living tissue radioactively decays via a first-order process. A one-gram sample of wood taken from a living tree gives a rate forcarbon-14 decay of 13.6 counts per. If the half-life for carbon-14is 5720 years, Explain how old is a wood sample that gives a rate for carbon-14 decay of 3.9 counts per minute?
