1. You learned that waves in the ocean, sound waves, and light waves all have certain things in common. They all carry energy. The velocity, frequency, and wavelength of each is connected by the same equation. Which type of wave would you most want to learn more about? Why does it interest you? What would you want to find out about it? Write your answers in 2-3 paragraphs. (10 points) Would you like to know more about how waves in the ocean move, how sound travels, or how light works?
2. If you could somehow travel inside an atom and look around, what part of the atom would you want to look at? Why? What would you want to understand better as a result of your "travels"? Write your answers in 2-3 paragraphs. (10 points) Do electrons or the nucleus interest you more? What questions do you still have about how an atom works?
Answers
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.
What are ocean waves?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.
What are waves?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.
Personally, 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 I'm certain that the moon's gravitational force is somehow implicated. Because that is basically the extent of my expertise on the matter. The mysteries of the water and the mysteries of space have always interested me. I'm still learning, so this combines a bit of both.The largest enigma in the interior of the atom something I would really like to understand is the nature of the connection involving neutrons as well as protons in the nucleus of an atom, which holds the nucleons together. Neutrons just don't have a positive electrical charge, whereas protons do. What kind of interactions is conceivable between charged as well as uncharged particles. Through my investigations into the internal workings of the atom, I hope to understand more about it.

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.

How many grams of water are needed to absorb 456 J if its temperature goes from 22.7 to 98.3 Celsius?
Answers
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
Change in temperature (ΔT) =?ΔT = T₂ – T₁
ΔT = 98.3 – 22.7
ΔT = 75.6 °CFinally, we shall determine the mass of the waterHeat absorbed (Q) = 456 J
Change in temperature (ΔT) = 75.6 °C
Specific heat capacity of water (C) = 4.184 J/gºC
Mass of water (M) =?Q = MCΔT
456 = M × 4.184 × 75.6
456 = M × 316.3104
Divide both side by 316.3104
M = 456 / 316.3104
M = 1.44 gTherefore, the mass of the water is 1.44 g

what is the 3-dimensional orientation of a sublevel known as?
Answers
The 3-dimensional orientation of a sublevel is known as atomic orbital.
In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.
Each sublevel has an orbital and it is oriented differently in 3-dimensional space.
The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.

What is an earthquake?
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.
