Carbon 14 is a radioactive isotope produced in the upper atmosphere by cosmic rays. It has a half-life measured as 5730 : 40 years. Since plants and animals absorb carbon from the atmosphere, the percentage of carbon a living organism contains that is carbon 14 is equal to the percentage of carbon 14 in the atmosphere. When an organism dies, however (or when a layer of wood is laid down as bark in a tree), it ceases to absorb carbon....
Carbon 14, (14^, 6 C ) is a radioactive isotope of carbon that has a half-life of 5,730 years. If an initial sample contained 1,000 14C nuclei, how many would still be around after 22,920 years?
A certain radioactive substance decays at a rate proportional to its remaining mass M. a. Express this rate of decay as a differential equation. b. When a living organism dies it ceases to replace the carbon isotope C-14, and 48. the C-14 that is present decays with a half-ife of about 5730 years. If archeologists discover a fossilized bone that has 30% of the C-14 of a live bone, approximately how old is it? A certain radioactive substance decays at...
please explain too 1) There is 1.3 radioactive carbon-14 atoms for every trillion carbon atoms in living organisms. Carbon-14 beta decays to nitrogen-14 with a half-life of 5730 years. (a) What is the activity due to carbon-14 in a 5o kg person? (Assume that 18% of the mass is carbon.) (b) Calculate Q for the decay.

Consider a pure sample of a radioactive isotope with a mass number of 52. If the sample has mass of 33 micrograms and the isotope has a half-life of 27.5 x106 years, determine the decay rate for the sample. Give your answer in decays/secondand with 3 significant figures.
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...
A Radioactive Isotope is 1. Time for half of a sample to decay from parent isotope to daughter isotope for radioactive atoms 2. The technique of getting the age of something by using unstable isotopes 3. An element that has unstable nuclei and will transform itself into another element 4. The process of an element transforming into another element by changes of its nucleus
Consider a pure sample of a radioactive isotope with a mass number of 46. If the sample has mass of 25.0 micrograms and the isotope has a half-life of 8.50x106 years, determine the decay rate for the sample. Give your answer in decays/secondand with 3 significant figures. Please show your work! I would like to understand the process. Thank you! Answer i think is in the range of 300-600 decay/sec It is not anything that is x10^...
Using Python 3... Question 4: Carbon dating (3 points) Archaeologists use the exponential, radioactive decay of carbon-14 to estimate the death dates of organic material. The stable form of carbon is carbon-12, and the radioactive isotope carbon-14 decays over time into nitrogen-14 and other particles. Carbon is naturally in all living organisms, and the carbon-14 that forms in the upper atmosphere enters into living things as long as they are taking in material (food, air, etc.) that contains carbon. We...
