Question
How is carbon dating used to determine the age of a fossil?
A. Measurement of the ratio of carbon-14 to carbon-12 and relating it to the half-life of carbon-14 gives the age of the fossil. B. Measurement of the amount of carbon-12 reveals how much carbon-14 was once incorporated into the fossil. C. Measurement of the ratio of nitrogen-14 to carbon-14 and relating it to the half-life of carbon-14 gives the age of the sample. D. Measurement of the rate at which carbon-14 is incorporated into the sample gives the age of the fossil.Explanation / Answer
we use
A = A0*(1/2)^(t/HL)
HL = 5730 years
we measure the ratio os C-14 vs C-14 from bprevious
A-->Measurement of the ratio of carbon-14 to carbon-12 and relating it to the half-life of carbon-14 gives the age of the fossil.
