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

Can someone please explain the cause and effect between the rearrangement of atoms and molecules in a chemical reaction and the different properties that the products have from the reactants.
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
Explanation:
Help! Please :) Thank you

Identify the force used on your arm when you walk a dog on a leash and it tries to chase something.
Friction
Gravity
Strong pull
Weak push
Answer: The force used on your arm when you walk a dog on a leash and it tries to chase something is known as Strong pull.Strong pull is defined a physical force which is usually aggressive orcoercive and it involves the movement in a particular direction due to different factors or reasons. The Dog in the example has a leash on and applies a force in the direction ofthe thing it wants to chase which is a perfect example of a strong pull.

It is important that engineers build a structure that is safe. What do they look for when testing their designs?
Failure points
Fair tests
Prototypes
Variables
Answer:
Failure Points
Explanation:
Engineers want to test the areas that may possibly fail when they are building designs so when they go to actually build it they know it will not fail.
