Question

Exponential decay, a paleontologist finds a bone that might be a dinosaur bone. in the laboratory she finds that the carbon-14 found in the bone is 1/12 of that found in living bone tissue. Could this bone have belonged to a dinosaur? Explain your reasoning. Hint- dinosaurs lived from 220 million years ago to 63 million years ago. Please show work!

Answer 1

do you know growth equations?

Answer 2

yes

Answer 3

assume the bone belongs to a dinosaur.......then the number of decays has to fall into the time period.........are you given the half life of C14?

Answer 4

no

Answer 5

find it in google. Then calculate how long it will take for it to decay to 1/12 of its original mass. If the answer falls in the time range, it's a dinosaur

Answer 6

ok
