EASYYYYYYYYYYY A batter hits two balls during practice. Ball A travels 10 meters, while ball B travels 12 meters. The batter decides to hit ball A with less force. How will this change the motion of ball B?
The motion of ball B will increase.
The motion of ball B will decrease.
The motion of ball B will stay the same.
The motion of ball B will become the same as ball A.
Answer:
The motion of ball B will increase
Explanation:
Because if you hit ball A with less force than ball B then that means that ball B will go faster because you had hit ball A will less force witch will not be as faster as ball B.
Answer:
The first one

What happens to potential energy when you move against the magnetic force?
Answer: The field produces a repulsive force pushing them apart. They repel each other. In this case, the closer they are, the higher their potential energy will be. If allowed to move, they may move as far apart as possible or one will swing around to change its orientation.
Explanation:

What does the conversation of mass say about the amount of atoms in the reactants compared to the products?
Answer:
the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
Answer:
[tex]\boxed {\boxed {\sf Atoms \ in \ reactants \ = atoms \ in \ products}}[/tex]
Explanation:
The Law of Conservation of Mass states that mass cannot be created or destroyed.
In a chemical reaction, this means the mass of the reactants (substances going in and being changed) must equal the mass of the products (new substances from the reaction).
In addition, the amount of atoms must stay the same. The atoms can and will reconfigure to form different compounds, but the number of atoms stays the same.

How are the volvox, euglena, paramecium, and amoeba similar and different in how they move, and eat?
Answer:
Both can hunt for their food (heterotrophs), but euglena can also make their own food (autotroph) with its chloroplasts. Amoeba have pseudopods to move/eat, but euglena have flagella to move. How are euglena and paramecium similar and different? ... Both also use flagella to move, but volvox move together in colonies.
