The normal activity of a living matter containing carbon is found to be 15 decays per minute per gram of carbon. An archaeological specimen gives 6 decays per minute per gram of carbon. If the half -life of carbon is 5730 years, estimate the approximate age of the specimen.

In a sample of rock the amount of radioactive carbon is 6.25%. If the half life of radioactive carbon is 5730 years then estimate the age of rock.

The activity of carbon -14 in a sample of charcoal from an archaeological site is 0.04 Bq. Determine the age of the sample. The half life of carbon -14 is 5730 years.

The normal activity of living carbon-containing matter is found to be about 15 decays per minute for every gram of carbon. This activity arises from the small proportion of radioactive "_6^14C present with the stable carbon isotope "_6^12C . When the organism is dead, its interaction with the atmosphere (which maintains the above equilibrium activity) ceases and its activity begins to drop. From the known half-life (5730 years) of "_6^14C , and the measured activity, the age of the specimen can be approximately estimated. This is the principle of "_6^14C dating used in archaeology. Suppose a specimen from Mohenjodaro gives an activity of 9 decays per minute per gram of carbon. Estimate the approximate age of the Indus-Valley civilisation.

The normal activity of living carbon-containing matter is found to be about 15 decays per minute for every gram of carbon. This activity arises from the small proportion of radioactive ""_6^14C present with the stable carbon isotope ""_6^12C . When the organism is dead, its interaction with the atmosphere (which maintains the above equilibrium activity) cases and its activity begins to drop. From the known half-life (5/30 years) of ""_6^14C , and the measured activity, the age of the specimen can be approximately estimated. This is the principle of ""_6^(14)C dating used in archacology. Suppose a specimen from Mohenjodaro gives as activity of 9 decyas per minute per gram of carbon. Estimate the approximate age of the Indus-Vally civillisation.

The normal activity of living carbon-containing matter is found to be about 15 decays per minute for every gram of carbon. This activity arises from the small proportion of radioactive ""_(6)^(14)C present with the stable carbon isotope ""_(6)^(12)C . When the organism is dead, its interaction with the atmosphere (which maintains the above equilibrium activity) ceases and its activity begins to drop. From the known half-life (5730 years) of ""_(6)^(14)C , and the measured activity, the age of the specimen can be approximately estimated. This is the principle of ""_(6)^(14)C dating used in archaeology. Suppose a specimen from Mohenjodaro gives an activity of 9 decays per minute per gram of carbon. Estimate the approximate age of the Indus-Valley civilisation.

The normal activity of living carbon - containing matter is found to be about 15 decays per minute for every gram of carbon. This activity arises from the small proportion of radioactive ._(6)^(14)C present with the stable carbon isotope ._(6)^(12)C . When the organism is dead, its interaction with the atmosphere (which maintains the above equilibrium activity. ceases and its activity begins to drop. From the know half-life (5730 years.) of ._(6)^(14)C , and the measured activity, the age of the specimen can be approximately estimated. This is the principle of ._(6)^(14)C dating used in archaeology. Suppose a specimen from Mohenjodaro gives an activity of 9 decays per minute per gram of carbon. Estimate the approximate age of the Indus-Valley civilisation.
