When you added the neutron to the atom, what is the new name?
Answer:
Isotope
Explanation: Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom.
Answer:
an isotope.
Explanation:
Isotopes are two or more types of atoms that have the same atomic number and position in the periodic table and that differ in nucleon numbers.

What are the three parts of sound? (Select all that apply.)
the transfer of energy through a medium
the detection of sound
the identification of pitch
the energy source
Sound is resistance in air made by waves. In fact it is the transfer of energy through a medium and it have a source. The frequency of sound waves is called pitch. Hence the three parts of sound is options 1, 3 and 4.
What is sound wave?Sound wave is a mechanical wave which transfer energy through a medium. There are two types of mechanical waves namely transverse wave and longitudinal waves.
Transverse waves are those in which the oscillation of particles is in a direction perpendicular to the wave. Whereas, in longitudinal waves, the direction of oscillation is along the wave.
Sound waves are longitudinal waves having certain frequency. The frequency of sound waves is called the pitch. Sound waves can be of low pitch or high pitch based on their energy. High energetic waves have higher pitch.

A) A galaxy that does not include our solar system
B) A dwarf galaxy
C) Galaxy containing earth(i think this one is right)
D) Galaxy destroyed in collision
Answer:
C
Explanation:
The Milky Way is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
Milky Way can be referred to as the galaxy which contains Earth . The milky way also comprises of other solar systems such as the Sun and billions of stars.
The name 'milky way' came about as a result of how the sky looks when viewing it at night. It contain several bands of color in a milky manner which are usually difficult to differentiate.
The milky way comprises of different processes such as force of gravity acting on it and also the channeling of energy needed to produce stars which aids vision in the night.

The electromagnetic spectrum is the portion of energy that reaches the Earth from the Sun. However, the human eye can still only detect a portion of that spectrum because of the _____________ of the visible light waves.
amplitude
wavelengths
crests
troughs
Answer: I’m stuck between amplitude and wavelengths but I do think it’s wavelengths.
Correct me if I’m wrong! ^^
The human eye can only detect a portion of that spectrum because of the wavelength of the visible light waves. Therefore, option (B) is correct.
What are frequency and wavelength?The wavelength of the light can be defined as the distance between the two adjacent points of a wave w.r.t. each other. Two crests on a wave are separated by a distance known as wavelength.
The frequency of the wave can be defined as the number of oscillations of a wave in 1 sec. The frequency has S.I. units per second or hertz.
The relationship between wavelength, frequency (ν), and speed of light (c) is as follows:
c = νλ
The part of the electromagnetic spectrum that is visible to the human eye is known as the visible spectrum. The electromagnetic radiation of the visible spectrum is known as visible light.
Human eyes can detect the wavelength of range from 380nm to 740nm. This wavelength range of visible light corresponds to a band of frequency between 405 THz to 790 THz.

Answer:
1. eyepiece
2. body piece
3. Adjustments
4. Arm
5. Objective lens
6. Stage
7. Mirror
8. Base
Explanation:
I hope this helps.
Here's the labeled list of different parts of a microscope using the word bank; Eyepiece (ocular lens), Objective lenses, Arm, Stage, Coarse focus, knob, Fine focus knob, Diaphragm or Iris diaphragm, and Light source (lamp or mirror)
Eyepiece (ocular lens): This is the lens at the top of the microscope that you look through to view the specimen. It typically provides a magnification of 10x.
Objective lenses: These are the lenses located on the rotating nosepiece, closest to the specimen. They come in different magnifications, such as 4x, 10x, 40x, and 100x, and are used to magnify the image of the specimen.
Arm: The arm is the curved part of the microscope that connects the eyepiece and the base. It is used to carry the microscope and provides a handle for holding it securely.
Stage: The stage is the flat platform where the specimen is placed for observation. It may have clips or a mechanical stage to hold the slide in place.
Coarse focus knob: This knob is used for large, rapid adjustments of the focus. It moves the stage up and down to bring the specimen into rough focus.
Fine focus knob: The fine focus knob is used for precise adjustments of the focus. It is used after the coarse focus to bring the specimen into sharp focus.
Diaphragm or Iris diaphragm: The diaphragm or iris diaphragm is located under the stage and controls the amount of light passing through the specimen. It helps in adjusting the contrast and brightness of the image.
Light source (lamp or mirror): The light source provides illumination for the specimen. It can be an electric lamp located at the base or a mirror that reflects natural light onto the specimen from above.
These are the essential parts of a compound light microscope, which is a widely used type of microscope for magnifying and observing small specimens in various fields such as biology, medicine, and materials science.
