Question

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

Answer 1

I'm pondering...

Answer 2

ok!

Answer 3

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

Answer 4

and N is the number of C-14 isotopes

Answer 5

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

Answer 6

the letter did not show :P

Answer 7

oops.. it is option D

Answer 8

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