## anonymous one year ago A paleontologist measures the ratio of carbon-14 to carbon-12 in a fossil skull found at a site. What technique is he using and for what purpose? A. using alpha emission to determine the structure of the skull B. using radioactive decay to determine the structure of the skull C. using gamma emissions to date the skull D. using radioactive decay to date the skull

I'm pondering...

ok!

3. Michele_Laino

it is option , since the decay equation is used. Here is that equation: $N\left( t \right) = {N_0}{e^{ - \lambda t}}$ where \lambda is the decay constant

and N is the number of C-14 isotopes

wait, which option did you say it was? :/

6. anonymous

the letter did not show :P

7. Michele_Laino

oops.. it is option D

8. anonymous

ohh okie:) i see now! thank you!!:D
