Question

If you know how much radioactive material the organism had to begin with, explain how you could use half-life to determine its age now.

Answer 1

Answer: We can calculate it with the radioactive half life equation

Step-by-step explanation:

If we already know the initial amount of radioactive material and its half life, we can leave that material for a specific known time and then measure how much of the material is left (since it follows the radioactive deacay) and use the results in the following formula:

`A=A_(o).2^{(-t)/(h)}`

Where:

`A` is the final amount of the material

`A_(o)` is the initial amount of the material

`t` is the time elapsed

`h` is the half life of the radioactive compound
