A piece of charcoal (essentially 100% carbon) from an archaeological site in Egypt is subjected to...
A 75 g sample of charcoal (assume only carbon) from an archaeological excavation is found to have an activity of 6 Bq from the decay of carbon-14. Use the following information to carbon-date the site. Activity of 1 g of fresh carbon = 0.25 Bq. half-life of carbon-14 = 5730 years.
The answer is not 13657.8 A piece of charcoal used for cooking is found at the remains of an ancient campsite. A 1.2 kg sample of carbon from the wood has an activity of 1660 decays per minute. Find the age of the charcoal. Living material has an activity of 15 decays/minute per gram of carbon present and the half-life of 14C is 5730 y.
A 2.10-g sample of wood from an archaeological site gave 8600 disintegrations of 14C in a 10-hour measurement. In the same time, a 2.10-g modern sample gave 19000 disintegrations. Calculate the age of the wood. The half-life of carbon-14 is 5730 years.
(4) (1 pt) A sample of bone is subjected to radiocarbon dating. The current decay rate observed for its carbon-14 content is 11.2 disintegrations per minute per gram of carbon. What is the age (in years) of the bone? The half- life for carbon-14 is 5.73x10 yrs., and the decay rate for carbon-14 in living organisms is 15.3 disintegrations per minute per gram of carbon.
An archeological artifact was subjected to radiocarbon dating. The artifact showed a carbon-14 decay rate of 12.2disintegrations/min per gram of carbon. Carbon-14 has a half-life of 5715 years, and currently living organisms decay at the rate of 15.3 disintegrations/min per gram of carbon. What is the approximate age of the artifact? Select one: A. 371 years old B. 6597 years old C. 851 years old D. 1867 years old
The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method. The activity of the sample is measured to be 0.671 times the Carbon-14 activity of living plants. What is the age of the sample in years? (The half-life of the Carbon-14 isotope is 5730 years.) Submit Answer Tries 0/20
Carbon-14 has a half-life of about 5730 years. If a sample from an archaeological site has only 12.5% of the normal C-14 abundance, it must be ___ years old.

1A)The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method. The activity of the sample is measured to be 0.741 times the Carbon-14 activity of living plants. What is the age of the sample in years? (The half-life of the Carbon-14 isotope is 5730 years.) B)A newly discovered particle, the SPARTYON, has a mass 945 times that of an electron. If a SPARTYON at rest absorbs an anti-SPARTYON, what is the...
explain 7 & 8 please Question 7 1 pts The AC activity of an artifact from a burial site was 8.7/min.g C. The half-life of C is 5730 years, and the current activity is 16.1/min.g C (that is, 16.1 disintegrations per minute per gram of carbon). How old in years) is the artifact? Enter number to 1 decimal place. Question 8 1 pts Analysis of an ant found in a piece of amber provided 10 disintegrations of 14C/min.g C, whereas...
