help im being TIMED 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.

Answers

Answer:

Explanation:

The batter aint changing the force he is using while hitting Ball B. Therefore, Motion of ball b will stay the same :D

Answer:

The third one

The Motion of ball b will stay the same

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.

Answers

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.

When you cut something in half, the resulting view is called a cross section. When you look at the cross section of an apple, you see several layers: the skin, the pulp, the core, and the seeds. Much like the apple, Earth is made up of layers, too. If you could look at a cross section of our planet, you would see the crust. the mantle, the outer core, and the inner core. If Earth were an apple, the crust would be the apples skin. The mantle would be the apples pulp, making up most of the inside. Earth also has a central core, similar to an apples core, though Earths core does not contain any seeds! Of course, scientists cannot cut the whole planet in half to see a cross section the way you can with an apple. How do you think scientists know about Earths internal layers?Scientists divide Earths interior into distinct layers.Scientists can distinguish different layers in Earth depending on the properties used to identify each layer. For example, scientists identify the crust, mantle, and core based on each layers basic chemical composition. In other words, the crust, mantle, and core are each made up of different chemical elements. The crust and mantle are composed primarily of the elements oxygen and silicon. These are known as silicates. Silicates of the mantle contain heavier elements. This makes them denser than those found in the crust. The core is composed of the densest materials, primarily iron and nickel. Earths layers can also be identified by using each layers physical state of matter. The crust and the uppermost part of the mantle, together, make up a layer called the lithosphere. The lithosphere is the cool, rigid, outermost layer of Earth. The lithosphere is in the solid In a typical silicate molecule, a silicon atom is bonded to four oxygen atoms. The atoms form a crystal structure.Scientists use models to represent the different layers of Earths interior.When constructing a model of the layers of Earth, scientists need to consider the chemical composition, state of matter, and thickness of each layer. Just like the skin of an apple, Earths crust is very thin compared to the other layers. It is about 2570 km thick beneath the continents. Under the oceans, the crust is only about 57 km thick; however, it is much denser. The mantle is much thicker than the crust is, taking up most of Earths volume. The mantle begins directly beneath Earths crust. It reaches all the way to the outer core, about 2,900 km below the planets surface. In other words, Earth is about 1% crust, 83% mantle, and 16% core.The crust and uppermost mantle are solid. The rest of the mantle is solid with plasticity. The core is made of very dense iron and nickel. The outer core is liquid, because it is hot enough to melt the iron and nickel. The inner core is solid. Even though it is as hot as the outer core, there is so much pressure at the very center of Earth that the iron and nickel stay in a solid state.Looking to the Future: Exploring Earths InteriorDespite what you may have read in stories or seen in movies, scientists have never journeyed to the center of Earth. In fact, scientists have never made it through Earths crust! However, this has not stopped them from trying. The crust at the bottom of the oceans is much thinner than the crust of the continents. Therefore, drilling through the oceanic crust is the best chance that scientists have to make it to the mantle. Can someone help with this Problem?
