Question
The half-life of carbon 14 is 5,730 years. Approximately, how old is a bone that has 70% of its original carbon 14?Question 3Select one:a.7,500 yearsb.7,000 yearsc.6,500 yearsd.6,000 yearse.Less than 6,000 years
Solution
To solve this problem, we need to understand the concept of half-life. The half-life of a substance is the time it takes for half of the substance to decay. In this case, the half-life of carbon 14 is 5,730 years, which means that after 5,730 years, half of the carbon 14 in a sample would have decayed.
However, in this problem, we are told that the bone still has 70% of its original carbon 14. This means that less than half of the carbon 14 has decayed, so the bone must be less than one half-life old.
Therefore, the bone is less than 5,730 years old. So, the answer is e. Less than 6,000 years.
