Mass of carbon in animal bone fragment found in an archeological site is 198g. If the bone registers an activity of 16 decays/s from radioactive 14C. What is its age?. Assume that the animal when it died that the ratio of 14C to 12C was 1.3x10-12. The half-life of 14C is 5730years.
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 ratio of carbon-14 to carbon-12 in a piece of charcoal from an archeological excavation is found to be one-half the ratio in a sample of modern wood. Approximately how old is the charcoal? a) 3,000 years b) 6,000 years c) 9,000 years d) 12,000 years
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
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.
(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.
The half life for the decay of carbon-14 is 5.73 x 10 years. Suppose the activity due to the radioactive decay of the carbon-14 in a tiny sample of an artifact made of wood from an archeological dig is measured to be 19. Bq. The activity in a similar-sized sample of fresh wood is measured to be 20. Bq. Calculate the age of the artifact. Round your answer to 2 significant digits. years X 5 ?
A sample of charred animal bones found in a cave has a carbon-14 decay rate of 5.2 disintegrations per minute per gram of carbon (5.2 dis/min-g C). Living organisms have a decay rate of 15.3 dis/min-g C. The half-life of carbon-14 is 5715 yr. How old is the bone sample? (All radioactive elements decay according to first order kinetics.) a)2.8 x 10 3 yrs b)3.9 x 10 3 yrs c)1.9 x 10 3 yrs d)8.9 x 10 3 yrs
Be sure to answer all parts. The carbon-14 decay rate of a sample obtained from a young tree is 0.264 disintegration per second per gram of the sample. Another wood sample prepared from an object recovered at an archaeological excavation gives a decay rate of 0.193 disintegration per second per gram of the sample. What is the age of the object? (The half-life of carbon-14 is 5715 years.) × 1 ol 1 years Enter your answer in scientific notation.
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...
