Sihle, an archaeologist from UWC finds an ancient wooden axe handle at an excavation site at Onderstepoort. He wants to determine the age of the axe handle. He takes a small sample of carbon from the axe handle and places it near a Geiger counter. The counter reads 5 counts/minute. He then takes the same mass of carbon from a living tree and finds that it has a count-rate of 40 counts/minute. a) How old is the axe handle? (assume the half-life of C-14 is about 6000 years) - choose answer below b) Explain your reasoning in 'Rationale O A. 18 000 years B. 12 000 years OC. 2000 years D. 6000 years
