The answer is as the slope of the line
Not only astronomers, but all scientists use the technique of rock dating to determine the age of the universe. From the Big Bang Theory, all the celestial bodies were made at the same time. So, the age of the Earth is just the same with the age of the universe. So, they gather rocks deep down in the crust of the Earth and let it undergo radioactive decay. By determining the amount of radioactive material left and half-life, they could compute the age of the Earth.

Explanation:
Step 1:
We know that the expression for potential energy is
PE = mgh
where, m =Mass
g = Acceleration due to gravity
h Height
Step 2:
Here m = ?
PE = 108486
h = 30 m
g = 9.8 ms⁻²
108486 =
