Step 1: Assuming some variables
To calculate the age of the rock using the decay of U-238 to Pb-206, you can use the concept of radioactive decay and the half-life of U-238.
The half-life of U-238 is given as 4.5 x 10^9 years, which means that half of the U-238 atoms will decay to Pb-206 in that time period.
First, let's define some variables:
- N0 :The initial number of U-238 atoms in the rock.
- N: The current number of U-238 atoms in the rock.
- t: The age of the rock in years.
- λ: The decay constant (λ = ln( 2) / half-life), which is the rate at which U-238 decays.
