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.

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.

Answer:1) person 2) person
Explanation:
I just did the assignment
The correct answer is the computer's thermal energy will be transferred to the human.
Why does energy flow from the computer to the person?Computers are often devices that transform electrical energy into thermal energy, which is then supplied to the user. The energy is transferred from the higher to the lower amount. In this example, the computer produces more thermal energy than the person, which is why energy flows from the computer to the person.Learn more about computer thermal energy here:-
