Sagot :
11460 years ago a sample of wood was the part of a living tree.
What is half-life?
The time required for half of something to undergo a process.
Carbon-14 has a half-life of 5,730 years. That means that no matter how many carbon-14 atoms were present when something died, after 5,730 years only half of them are left the rest have decayed to nitrogen.
The half life of C-14 is [tex]t_{\frac{1}{2}}[/tex] =5730 years.
This means that if you start with a sample of 100g, only 50g will be left in 5730 years.
Here, Only 25g is left, therefore the number of years is =5730 × 2 = 11460years.
Hence, 11460 years ago a sample of wood was the part of a living tree.
