In the carbon dating process for measuring the age of objects, carbon-14, a radioactive isotope, decays into carbon-12 with a half-life of 5730 years. A Cro-Magnon cave painting was found in a cave in Europe. If the level of carbon-14 radioactivity in charcoal in the cave is approximately 16% of the level of living wood, estimate how long ago the cave paintings were made. (Hint: Let the initial amount of carbon-14 be C0. Round your answer to the nearest year.)

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

1. The nucleus 14C (half life 5730 y) is used in radiocarbon dating to determine the age of previously living material. (a)A certain sample of wood currently shows a decay rate of 35.0 decays/s of 14C The wood is taken from a structure that was built from a tree that was cut 7,000 years ago. What would have been the 14C decay rate of this wood sample when the tree was cut? (b) Find the total binding energy (in MeV)...

1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...

If a radioactive isotope has half-life h, then the number of atoms in a sample is given by a(t)=a-2-/h where ao gives the number of atoms in the sample at time 0. The radio active decay of carbon-14 leads to clever way of determining the age of fossils and remnants of plants and animals. When an organism dies, the radioactive carbon- 14 in it decays, with half of it gone in 5,730 years. a. Suppose a mummified cat has a...

Scientists can determine the age of ancient objects by a method called radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, C , with a half-life of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates through food chains. When a plant or animal dies it stops replacing its carbon and the amount of "C begins to decrease through radioactive decay. Therefore, the level of...
