Answer:
Since they are in a geostationary orbit, the GOES satellites provide continuous monitoring of the Earth's surface. They are able to constantly monitor the life cycle of significant weather such as hurricanes, tornadoes, flash floods, and hail storms.
The wall would absorb extra heat during the day when the sun is out, then release the heat back into the room when the sun goes down.
Explanation:
The chemical elements goes from 30g to 15g to 7.5g to 3.75g.
Therefore, it has gone through 3 half lives.
The percentage abundance of 6Y is 0.102.
An Isotope refers to two or more atoms that has the same atomic number but different mass numbers.
We have been informed from the question that the atomic mass of the element is 6.9412 amu.
Let the abundance of isotope 6Y be x
Let the abundance of isotope 7Y be 1-x
Hence;
6.9412 = 6.015123x + 7.016005(1 - x)
6.9412 = 6.015123x + 7.016005 - 7.016005x
6.9412 - 7.016005 = 6.015123x - 7.016005x
-0.102 = -1x
x = -0.102/-1
x = 0.102
Hence the percentage abundance of isotope 6Y is 0.102.
