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: The height of the ocean floor near the middle slit is much greater than the elevation close to the side slit. This disparity influences the depth of the ocean since the water depth would also be higher as the elevation and pressure are higher.
Because humans have a lot more wonders and information than physicals
