The half-life for radioactive decay of ${}^{14}C$ is 5730 yr. An archaeological artifact containing wood had only $80\%$ of the ${}^{14}C$ found in a living tree. Estimate the age of the sample.

Q.

The half-life for radioactive decay of ¹⁴C is 5730 years. An archaeological artifact containing wood had only 80% of the ¹⁴C found in a living tree. Estimate the age of the sample.

Q. The half-life for radioactive decay of $C-14$ is $5730$ years. An archaeological artifact containing wood had only $80$% of the $C-14$ found in a living tree. The age of the sample is ?

Q. A piece of wood from an archaeological source shows a ${}^{14}C$ activity is 60% of the activity found in fresh wood today. Calculate the age of the archaeological sample. $(t_{1/2}=C=5770yr)$

Q. The age of a sample of wood (in years), if only $\frac{1}{16}$ part of original ${}^{14}C$ is present in its piece, is, (Half life of ${}^{14}C$ is $5580$ years)

Q. An old sample of wood from an archaeological excavation was found to have a radioactivity of about 140.8 counts per minute due to ${}^{14}C(t_{1/2}=5730$ years) as against 281.6 counts per minute for that of a freshly cut piece of wood. What is the age of the old sample of wood (in millennia, 1 millennium= 1000 years)?
