Answer:
After three half-lives, it is 7:1
Explanation:
- The rate at which the decay of the radioactive isotope is said to be half-life and is represented as the half-life of the atoms and the matter to disintegrate itself.
- The two radioactive isotopes are K 40 and Ar 40. After the K-Ar dating, they contain minerals such as the clay mica and the temphra minerals and Half-life of the K 40 is 1.3 more than 100,000 years i.e 10x9 years for Ar 40.
- <u>Thus the K 40 has to divide as three half-lives have passed if the ratio of argon to potassium atoms is 7:1. At the end of one half-life, the ratio of the number of argon to potassium atoms is 1:1. and two half lives its 3:1 thus after the third half-life it becomes as 7:1.</u>
Answer:
Central Asia and Eastern Asia
Explanation:
Answer:
<u>Option-(B):</u> The condensation process has a drying effect on the air.
- As, the different layers inside such a region's atmosphere is dried out by the process of condensation. And most of the region is left with no to less then the normal level of moisture inside the state of California,US. While, most of the species living in the region are more arranged in terms or having a very specific system to resist the heat present inside the region.
- As, such conditions gives rise to more high levels of temperature inside the different regions.But speaking specifically of the Iee(Ieeward)side of the Sierra Nevada's of California which is targeted by the displacement of the moisture or we can simply say that the droplets from the atmosphere is all due to the presence of the condensation processes inside the regional atmosphere.
