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...

The radioactive isotope carbon-14 is used for radiocarbon
dating. The half-life of carbon-14 is years. A wooden artifact in a
museum has a count that is times that found in living organisms.
Estimate the age of the artifact.
The radioactive isotope carbon-14 1s used for radiocarbon dating. The half-life of carbon-14 is 5730 103 years. 14 A wooden artifact in a museum has a C count that is 3.13 x 10 times that found in living organisms Estimate the age...

The half-life of carbon-14 is 5730 years. How long does it take for 3.6 grams of carbon-14 to be reduced to 1.3 grams of carbon-14 by radioactive decay? years (Do not round until the final answer. Then round to the nearest hundredth as needed.)

Carbon-14 is a radioisotope that is used for dating biological organisms. The half-life of C-14 is 5730 years. When a one-gram sample of carbon from fresh peat is measured for radioactivity, 900 beta decays are recorded every hour. A one-gram sample of carbon is obtained from a peat deposit and is measured for radioactivity. If 113 beta decays are observed every hour, how many half-lives of C-14 have passed since the deposit was formed? A. 1/8 B.3 C.113 D.8 Approximately...
Carbon-14 is a radioactive nucleus with a half-life of 5760 years. Living matter exchanges carbon with...
Carbon-14 is a radioactive nucleus with a half-life of 5760 years. Living matter exchanges carbon with its surrounding so that a constant level of 14C is maintained, corresponding to 15.3 decay events per minute. Once living matter has died, carbon contained in the matter is not exchanged with the surroundings, and the amount of 14C that remains in the dead material decreases with time due to radioactive decay. Consider a piece of fossilized wood that demonstrates 2.4 14C decay events...

This Question: 1 pt 20 of 20 (15 complete The half-life of carbon-14 is 5730 years. How long does it take for 2.2 grams of carbon-14 to be reduced to 0.2 grams of carbon-14 by radioactive decay? (Do not round until the final answer. Then round to the nearest hundredth as needed.) Enter your answer in the box

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,...
