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.
The rock is 2000785 years old.

Explanation:
Hurricanes bring strong winds, heavy rain, and the threat of flooding or storm surge. During a hurricane, the wind speeds increase dramatically, and the hurricanes can even spawn tornadoes.
Soil erosion is not decreased, but rather increased drastically and entire beaches are often swept away by the winds and rains. If anything, air pollution over the urban area hit by the hurricane would be temporarily cleaned up by the storms.
