Carbon dating used to determinethe age of fossilized trees is based on monitoring the content of radioactive 14_6 C in the tree. Remembering that radioactive substances decompose or decay at a rate proportional to the amount of the substance present, what would be the "14_6 C content (as a fraction of No) of a fossilized tree that is claimed to be 4000 years old if the half-life of "14 _6 C is 5715 years. The amount of ",C still present at any time in the tree may be denoted as N and No, is the initial amount of 14_6,C.
