Question

ANYONE!!
??Prehistoric cave paintings were discovered in a cave in France. The paint contained 14% of the original Carbon-14. Estimate the age of the paintings.

Answer 1

So you know the half life
\(t_{1/2}\) of \(^{14}C\) is \(5730 \text {yr}\)

Answer 2

\[N(t)=N_02^{-t/t_{1/2}}\]
\[\frac{N(t)}{N_0}=2^{-t/t_{1/2}}\]

Answer 3

\[\frac{N(t)}{N_0}=\frac{14\%}{100\%}=14\%\]

Answer 4

take long to base two
