For which could carbon-14 dating be used?Multiple choice question.A)a marble column from ancient ChinaB)dinosaur fossils that are millions of years oldC)rocks that are billions of years oldD)a fragment of wood from a Colonial house
In the process of radiometric dating, if the percent of the original amount of carbon-14 present in a fossil is 12.5%, how old is the fossil? The half-life of carbon-14 is 5,730 years.Multiple choice question.11,460 years old17,190 years old5,700 years old22,920 years old
dating involves assigning a specific age to a fossil by testing either the fossil or the sediments above and below it.
Carbon-14 is a radioactive nucleus with a half-life of 5760 years. In livingmatter the amount of carbon-14 decays at a rate of 15.3 decay events perminute per gram of carbon. A fossil is analysed and found to have a carbon-14 decay rate of 7.70 decay events per minute per gram of carbon. How oldis the fossil?
