Explanation:
This calculator will find the missing variable in the physics equation for force (F = M * a), when two of the variables are known.
Answer: Option (a) is the correct answer.
Explanation:
Subscript present in chemical formula of a compound represents the number of atoms of the element actually present in it.
For example, in 
the subscripts present in it are 7, 7, 1, and 2.
A subscript is not responsible for determining the relative mass of each type of an atom because a subscript simply represents the number of atoms of each type of an element participating or combining with other atoms of a compound.
Thus, we can conclude that the statement subscripts represent the relative mass of each type of atom in the compound, is false.
The Nazca plate is converging with the South American plate.
Explanation:
The Andes Mountains are formed as a result of the convergent of the Nazca plate and the South American plate.
This mountain range typifies the geology and geography of the South American continent.
- Along this convergent margin, one plate subducts beneath the other.
- The oceanic plate due to its density goes into the mantle.
- The causes the continent riding to obduct and be forced.
- With rising magmatic bodies beneath, the continent further pushes up to form the Andes ranges.

This one is easy. It's just addition and subtraction. Add the partial pressure of Argon and the partial pressure of Helium:
152 kPa
<u>+305 kPa</u><u>
</u> 457 kPa
Next, subtract the result from the total pressure:
1015 kPa
<u>- 457 kPa</u>
558 kPa
