74. Carbon-14 is a radioactive isotope used to determine the age of samples of organic matter. The amount of carbon-14 in a sample decreases once the organism is no longer alive. The half-life of carbon-14 is approximately 5730 years. This means that every 5730 years, the amount of ...
If the half-life of carbon-14 is 5730 years, and you have a sample that has lost 80% of its carbon-14, how old is this sample? If the half life of carbon-14 is 5730 years, and you have a sample that has lost 80% of its carbon-14, how old is...
18 The radioactive isotope carbon-14 undergoes decay with a half-life of 5730 years.While an organism is living, it takes in carbon from the atmosphere and the ratio of carbon-14 to the stable isotope carbon-12 in the organism is constant. After death the ratio changes, as the carbon-...
The half-life of carbon-14 is 5,730 years. This means that it takes 5730 years for a mass of carbon-14 to radioactively decay to half its mass...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answe...
To determine how long the piece of wood has been buried, we can use the concept of half-life and the decay of carbon-14. Here’s a step-by-step solution:Step 1: Understand the given data - The half-life of carbon-14 (C-14) is g
half-life of a radioactive element is defined as the time that it takes for one-half a quantity of the element to decay. Radioactive Carbon-14 is found in all living organisms and has a half-life of 5730 years. Archaeologists use this information to estimate the age of fossils. Consider...
The half-life of carbon-14 is 5730 years, which means that it will take 5730 years, on average, for half of the initial substance present to decay (Long - parks.ca.gov). Although the ratio of carbon-14 to carbon-12 atoms is only a linear relationship, I am looking to explore ...
(4)A wooden artifact from an ancient tomb contains 65% of the carbon-14 that is present in living trees. How long ago was the artifact made? (The half-life of carbon-14 is 5730 years.) 相关知识点: 试题来源: 解析 (1) ① ②1.6 g ③70 yr (2)18 yr (3)149 h (4)3560...
(The half-life of Carbon-14 is 5730 years.) Estimating the Age of Fossils Using Carbon-14 Quantities All living things maintain a certain quantity of carbon-14 in their bodies. Once they die, this carbon-14, being radioactive, begins to decay away at...
What is the rate of radioactive decay? The rate of decay for carbon-14 is -0.693 B and its half-life is 5,730 years. If an organism has 45% of its carbon-14 compared to the living sample, how old is the fossil? What decays first during radioactive decay?
