Carbon dating for archeological materials is based on the fact that a plant, after its death, stops absorbing radioactive C-14 as CO2 from the atmosphere. This radioactive carbon accounts for 0.10% of the total carbon content at death. After death, the C-14 decays at its characteristic rate. A piece of straw from a brick excavated from within an ancient ruin shows a C-14 content of 0.089%. Estimate the age of the ruin. (For C-14, T1/2 =5715 years)
