<h2>Hello!</h2>
The answer is: The mass number of an atom is obtained by totaling the number of protons and neutrons.
<h2>
Why?</h2>
The atomic mass can be calculated by the sum of the protons and neutron mass of an element.
We should not confuse the atomic mass with the relative atomic mass since the relative atomic mass of an element is the average mass of its particles/atoms compared to 1/12th the mass of a carbon-12 particle/atom.
Have a nice day!
Answer: The United States bought the Louisiana Territory from France in 1803 for $15,000,000. The French leader, Napoleon Bonaparte sold the lad to President Thomas Jefferson because he needed money for the Great French War
Explanation:
Answer:
As the <u>temperature inversion</u> occurs around this zone
Explanation:
- Troposphere The lowest layer of atmosphere found on the surface of the earth from 0 to 30 kilometers it's wider in equator i.e 18 km and narrows at poles till 6-8 km only. At this layer, 90 % of all convective activity takes place, turbulence and cloud formation like stuff.
- Consists of 80% of water vapor and dust particles. In troposphere the temperature in the air decrease with gain in height with a height of an overall positive lapse rate of 6.5 degrees C / km. The onset of tropopause the region where mixing stops and temperature remains constant and extends up to a layer of 11 to 20 kilometers.
- However, lapse rate variation sometimes occurs in between this sphere and affects the altitude of the tropopause. The seasonal effect is strongest at the mid-latitudes and varies with changes latitudes.
I think the Earth would say "There are lots of people I'm trying to hold up here. it's getting pretty heavy to be honest. also, they keep using all my stuff!!"
