Answer: The rock is 2000785 years old.
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = initial amount of the reactant = 800
x = amount of daughter isotope = 600
a - x = amount left after decay process = amount of parent isotope = (800-600) = 200
Half life is the amount of time taken by a radioactive material to decay to half of its original value.

- If the planet was left without the sun then life would not have existed on the planet as the root driving factor would have been lost, in other terms such type of hypothesis would have not been possible due to gravitational pull and other factors like density.
