The statement "<span>For water to become a mechanical weathering agent through ice wedging, it needs to go through a cycle of freezing and thawing." is true</span>
Answer:
The answer is acceleration.
Explanation:
Acceleration- When it comes to science, Force is defined as a "push or pull" of an object with mass that causes it to change velocity.
Balanced Force- This occurs when two forces of the same mass or size are acting on a particular object in opposite direction. The object being acted upon could <em>either stay in its place or move in a uniform speed and direction.</em>
Unbalanced Force- This occurs when the forces applied are not equal and are of different direction. For example, a 55-kg person pulling a 30-kg cart. The cart will move to the direction of the pull.
Thus, when forces acting on an object are unbalanced, it causes the object to accelerate. This acceleration is directly proportional to the "net force", but is inversely proportional to the mass or size.
<u>A net force</u> is the total amount of force that is acting on the object.

Answer:
For a volume of 1 liter, we have a total mass of 220 grams of CaCl2 ( Option A)
Explanation:
<u>Step 1: </u>Given data
The concentration of the solution we want to make is 2M
2M = 2 moles/ L So the volume = 1L
The molar mass of CaCl2 is = 40 + 2*35 = 110g/mole
<u>Step 2:</u> Calculate number of moles
If we consider the volume = 1 L then for a concentration of 2M, this means the number of moles is 2
<u>Step 3:</u> Calculate mass
The molar mass of CaCl2 = 110 g/mole
This means 110 grams per 1 mole
for 2 moles the mass is 220 grams
This means that for a volume of 1 liter, we have a total mass of 220 grams of CaCl2
