Answer:
See explanation below for answer.
Explanation:
Newton's third law of motion states that, for every action, there is an equal and opposite reaction.
In the scenario presented above, we can see that for every time the child pushes against the ground, the ground also pushes against the child with opposing but equal force, that corresponds to the force that the child has pushed against it with.
This action and reaction is what enables the child to be able to jump the rope.
Therefore, the action is the child pushing against the ground, the reaction is manifested in the jump, as the ground pushes against the child with equal force.
Heat up the solvent. This will cause the molecules of the solvent to become more energized and "expand" to allow for more solvent to be added. However, once the solvent cools down, the extra solute may fall out as a precipitate.
This is how rock candy is made, by the way.
The units of ppm means parts per million. Also, It is equivalent to milligrams per liter. It is one way of expressing concentration of a substance. It u<span>sually used to describe the concentration of something in water or soil. We calculate the mass of CaCO3 as follows:
Mass = 75 mg/L (.050 L) = <span>3.75 mg CaCO3</span></span>
