Answer:
I do believe that it is a trick question on where the first civilization was located. but I do remember from high school that it was part of Syria. Or Iraq. I think it was Mesopotamia.
During a volcanic eruption, the geosphere always interacts with the atmosphere, and that is the case with Mount Saint Helen's as well. During the eruption, the volcano which is part of the geosphere, releases lot of gases, ash, debris into the atmosphere. As they are propelled into the atmosphere, these volcanic products became part of the atmosphere, thus affecting its composition and properties, giving us a nice and simple example of interaction between the two spheres.
In physical science, pressure quantifies the amount of force that is applied at a certain area. Mathematically, this can be transformed as,
Pressure = Force / Area
It is also to be noted that force is the product of mass and acceleration due to gravity.
Force = mass x acceleration due to gravity
Substituting,
Force = (350 kg) x (9.8 m/s²)
Force = 3430 N
Then, substitute this to the first equation,
Pressure = 3430 N / 1m²
<em>ANSWER: Pressure = 3430 N/m² = 3430 Pa</em>
Answer:
C) when nuclear fusion begins in the core
Explanation:
- <u>The protostar is a main-sequence star that has a core temperature that exceeds abut 10 million K and is needed for the hydrogen to operate efficiently and the </u><u>length </u><u>of this process depends on nature and the stellar </u><u>mass</u><u>, as the huge massive star have a greater and bigger core and fusion takes fast.
</u>
- A protostar is also called as primitive star and represents the earliest phases of the process of the stellar evolution and takes place after it leaves form the main sequence star.
