Answer:
A jet stream that alternates between hot and cool periods.
Explanation:
Winds typically travel at the very same latitudes, but Rossby waves occur when winds shift it into hurricane pattern. The Rossby waves go in a north-south direction and then return again. Whenever the Rossby waves' breezes swing up, they transport warm air first from tropical to the northern, while when they swing down, they transport cold air from either the Arctic to the south, resulting in alternating warm and cold spells.
Answer: The rock is 2000785 years old.
Explanation:
Expression for rate law for first order kinetics is given by:
![t=\frac{2.303}{k}\log\frac{a}{a-x}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B2.303%7D%7Bk%7D%5Clog%5Cfrac%7Ba%7D%7Ba-x%7D)
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.
![t_{\frac{1}{2}}=\frac{0.693}{k}](https://tex.z-dn.net/?f=t_%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cfrac%7B0.693%7D%7Bk%7D)
![k=\frac{0.693}{1000000}=0.000000693years^{-1}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B0.693%7D%7B1000000%7D%3D0.000000693years%5E%7B-1%7D)
![t=\frac{2.303}{0.000000693}\log\frac{800}{200}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B2.303%7D%7B0.000000693%7D%5Clog%5Cfrac%7B800%7D%7B200%7D)
![t=2000785years](https://tex.z-dn.net/?f=t%3D2000785years)
