Explanation / Answer

Part A : ratio(14C/12C)

k = 0.693/t1/2 = 0.693/5730 = 1.21 x 10^-4 y-1

ln(14C/12C) = -kt = -1.21 x 10^-4 x 472

ratio(14C/12C) = 3.31 x 10^-3

Part B : ratio(14C/12C)

k = 0.693/t1/2 = 0.693/5730 = 1.21 x 10^-4 y-1

ln(14C/12C) = -kt = -1.21 x 10^-4 x 512

ratio(14C/12C) = 0.94

Part c : With 0.1% uncertainty, the radiocarbn dating will be able to distinguish between AD472 and AD512 eruptions.

Yes
