True or false. The epicenter of the earthquakr is directly below the focus

Answers

True because imagen the earth's crust the epicenter is in the bottom of the focus

The epicenter is where the Earthquake practically starts from. The epicenter is, in a sense, the focus. But in other words, this is true.

Answers

2.26%, 26.8%, 2 2/5, 2.62, 271%

Hope this helps! :D

2.62
2.50
26.8% - .268
2.26% - .0226
271% - 2.71
Converting a Percent to a Decimal is by dividing by 100.

so your answer would be

Why do science textbooks tend to focus on three states of matter rather than four?

Answers

Science textbooks tend to focus on three states of matter rather than four because they have been present extensively in nature, and are responsible for the majority of actions.

The matter is anything that has mass and occupies space. The matter can be present in 3 states, namely:

Solid

Liquid

Gas

The solid-state of matter has been the one responsible for the tight bond between the atoms. The solid-state of matter has been found to have a tough structure.

The liquid-state of matter has been the one having the one that has loosely bonded atoms, as compared to the solid atom. The liquid state has fixed volume but can acquire the shape of any utensils in which it has been placed.

The gases are very loosely bonded atoms. The air has been the best example of the gaseous state of matter.

These three states have been present extensively in nature, and are responsible for the majority of actions. Thus, they have been focused on in the science textbooks.

However, the fourth state of matter has been plasma, It has been the ionized gas state existing between the solid and gas. The state has not been existing much in nature, thus has not been focused on.

For more information about the states of matter, refer to the link:

There are three states of matter:

- Solid
- Liquid
- Gas

There is also one more, which is not mentioned much:

- Plasma

This state of matter is not mentioned much because it is not found in a large amount. We can't see plasma. It has properties that are different than the other states.

When is energy used? please explain and give me an example.

Answers

Energy could be chemical, radiant, electrical, mechanical, kinetic, or thermal. These are all types of energy. Kinetic is when the thing object or person is moving. On the other hand electrical is something that powers your phone or tablet. Hope this helps! Mwah!

Can't help you on 1-4...I'm not very good with energy transformations.
5. coal, oil/petroleum, natural gas; water, wind, plant (there's a name for energy sources coming from plants, but I can't remember it)
6. Metals are lustrous, malleable, and good conductors of heat. Nonmetals are dull, brittle, and poor conductors of heat.
7. Crust is solid, mantle is solid, outer core is liquid, inner core is solid.
8. Millimeters, centimeters, meters, kilometers, milliliters, liters...that's all I can think of.
9. Gravity is the force that pulls objects towards the center of something. Earth's gravity keeps us all on the ground.
10. Anything that causes an object to move.
11. Mass is how much stuff is in something; weight is how heavy something is.
12. Pangaea
13. It's the biggest celestial body in our solar system.

10) A force is directly proportional to acceleration
11) Mass is the amount of matter contained in a body and weight is the force which a huge mass ( like that of sun) exerts on a mass.
12) Eurasia
13) It is because the sun has a huge mass ( Gravitational force is directly proportional to difference in mass)
14) Comet is a celestial object of a solar system that orbits the sun. It is not like plamtes, has a comparaitively less mass and orbits are long.
15) It depends on the distance ( directly proportional)
19) Dust, heat, hydrogen and helium.
