Q16 [8 pts.]: An ancient scroll has been found, and as an archaeologist you want to find how old it is using radiocarbon dating. The carbon-14 in the parchment comes from the living organism from which it was manufactured. Recall that the amount of Carbon-14 remaining in an object after t years is given by C(t) = Co 5730 where Co is the initial amount of carbon-14 in the object. (a) If a different scroll was found to be 4000 years old, how much carbon-14 is left in it compared to the typical amount found in a newly manufactured scroll of the same material? Interpret your result in words. (b) Given that the amount of carbon-14 found in the scroll parchment was measured to be 70% of the amount of a newly manufactured piece of parchment of the same material, estimate the age of the scroll. + Page 11 / 13 6 tv MAR 15
