Not every earthquake has a(n) Foreshock, but every earthquake has an Aftershock that occurs in the Same place as the mainshock.

An earthquake is defined as a natural disaster in which there are tectonic plates that are present on the earth's crust collides with each other.

An Earthquake can be minor as well as natural depending upon the frequency it causes the damage. Earthquake is the Shaking of Earth and was much destruction of the economy and manpower.

Surroundings are being disturbed like trees will fall, and buildings will collapse which will cause damage to the economy as well as to human life.

Foreshock is the before shop which happens before the earthquake and aftershock is the other socks that happen after the earthquake

Thus, the correct options are 1. Foreshock, 2. Aftershock, 3. The Same place as.

Answer:

Explanation:

1)  I personally would want to learn more about how the waves in the ocean move. About what causes high tide. What causes low tide. Why some waves are big and some small.  

I know it has something to do with the gravitational pull of the moon. But that is as far as my knowledge extends on the subject. I have always been fascinated with the secrets of the ocean and the secrets of space. To me learning, this is a little of both.

2)  The nature of the interaction between neutrons and protons in the atomic nucleus, which binds the nucleons together, is the biggest wonder in the inside of the atom that I would like to really know. Protons have a positive charge, but neutrons do not. What form of interaction between a charged particle and an uncharged particle is possible? That is what I expect to learn more about as a result of my explorations into the inner workings of the atom.

The inside of the atom is made up of the nucleus and electrons that travel about in orbits. The nucleus is made up of protons and neutrons. Electrons have a negative charge, protons have a positive charge, and neutrons have none. The nucleus is held together by electrostatic interaction between electrons and protons. The majority of the mass of an atom is made up of protons and neutrons.

I'm interested in finding out more about ocean waves travel. regarding the reason for high tide. what brings on a low tide. Although some waves become also large while others are smaller.

Ocean waves seem to be alterations to the ocean's surface. They could be produced by water being moved by the wind, gravity, as well as other forces.

A disturbance that moves from one place to another across a medium has been referred to as a wave. As an illustration of a wave, think of a sinuous wave.

Answer:

1) Gas

2) Higher

3) Increases

4) Higher

Explanation:

Answer:

1.514 moles

Explanation:

For this problem you want to use dimensional analysis and cancel out your molecules of sugar and be left with moles of sugar. We know that 1 mole (of anything) = 6.022 x 10 ^ 23 molecules, so we should use that conversion to help us. Start with 9.12 x 10 ^23 molecules and divide by 6.022 x 10 ^ 23 molecules, and you will be left with moles.

Answer:

The molecular structure affects solubility mainly biased on its polarity or bonded ions.

Explanation:

Polar molecules will better interact with the water molecules and will dissolve easier. Nonpolar molecules can dissolve if they are small enough, however they don't interact well with the polar molecules. Bonded ions, such as NaCl split into a cation Na and an anion Cl which the positive charge on the Na will be attracted to the oxygen, and the negatively charged Cl will be attracted to the positive Hydrogen.

**Remember this rule, like dissolves like, meaning nonpolar dissolves nonpolar and polar dissolves polar.

Answer:

I believe A is the correct answer.

Explanation:

I note that another response includes C. as another correct answer.  It is possible, but it depends on what is meant by "fixed shape."  I interpret "fixed shape" as the collection of the gases forming a fixed shape on their own.  Gases fill the container they are in (be it a flask, room, or a planet, so they have a fixed shape by that definition.  But a primary definition of gases is that that take on the shape of their container, not a shape of their own.

A. is correct because perfect gases have no interactions (AKA the Ideal Gas Laws).  They may have interactions, and often do, but they are weak.  That's why the ideal gas laws are a good first approximation to how gases change volume based on temperature and pressure.

Answer: B.

Explanation:

Explanation:

1. subatomic particles. 

2.proton, electron and neutron

3.The atomic mass of an element is actually the sum of the MASSES of protons and neutrons in AN atom of that element

4.An element's atomic number is equal to the number of protons in the nuclei of any of its atoms

5. Number of Protons = Atomic Number

Number of Electrons = Number of Protons = Atomic Number

Number of Neutrons = Mass Number - Atomic Number

For krypton:

Number of Protons = Atomic Number = 36

Number of Electrons = Number of Protons = Atomic Number = 36

Number of Neutrons = Mass Number - Atomic Number = 84 - 36 = 48

6. electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg

7.The center of the atom is called a nucleus

8. Negatively charged particles are found in multiple layers outside the nucleus of the atom. These particles are called electrons, and they orbit in various energy levels around the atom's nucleus.

9. A charged particle is also called an ion

Answer:

3.917 x 10 ^ 23

Explanation:

You just want to use dimensional analysis to solve. So first start with 122g of copper(II) nitrite, and divide by the molecular weight to get it into moles. Then you know that 1 mole = 6.022 x 10 ^23 molecules (Avogadro's Number) so multiply that by your current moles. A hint for these problems always convert what you were given to moles since it is easy to get to a lot of things through them. ** Use the molar mass/molecular weight for going from grams to moles or moles to grams and use Avogadro's number when going from moles to atoms/molecules or reverse.

Explanation:

The mass of water needed to absorb 456 J is 1.44 g

We'll begin by calculating the change in the temperature of the water.

Initial temperature of water (T₁) = 22.7 °C

Final temperature (T₂) = 98.3 °C

ΔT = T₂ – T₁

ΔT = 98.3 – 22.7

Heat absorbed (Q) = 456 J

Change in temperature (ΔT) = 75.6 °C

Specific heat capacity of water (C) = 4.184 J/gºC

Q = MCΔT

456 = M × 4.184 × 75.6

456 = M × 316.3104

Divide both side by 316.3104

M = 456 / 316.3104

Therefore, the mass of the water is 1.44 g
