In the given question, the amount of matter in a given space or volume is called density.
Matter is defined as any substance or anything that has mass, and which occupies space.
Density is a physical property of matter and can be defined as the mass of an object divided by its volume. Density has unit typically in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
It is an important property of matter because it helps to identify and distinguish different materials based on their mass and volume.
Therefore, density is the amount of matter in a particular region or volume.

In your own words, describe the region around the atom
Answer:
Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.

What is the funtion of the lungs in the respiratory system? (Use complete sentences.)
Answer:
The lungs' main role is to bring in air from the atmosphere and pass oxygen into the bloodstream. From there, it circulates to the rest of the body. Help is required from structures outside of the lungs in order to breath
Explanation:
Explanation: The lungs are the most important part of the respiratory system. They give air to serve the whole entire body. Lungs are one of the most vital organs of the body, since they help us breathe, and if we did not breathe, we would die.

Which form of energy is used as a roller coaster moves down the track?
a roller coaster moving down a track
Chemical energy
Light energy
Mechanical energy
Solar energy
Answer:
Mechanical energy
Explanation:
To investigate how mechanical energy affects the number of times a ball will bounce back, Maria dropped a ball from three different heights. Which of the following would be a reasonable conclusion from this experiment?
The height from which a ball is dropped does not affect the number of times it bounces.
Increasing the height will give the ball more energy and will increase the number of times it bounces.
Increasing the height will give the ball less energy and will decrease the number of times it bounces.
Decreasing the height will give the ball more energy and will increase the number of times it bounces.
Answer:
Increasing the height will give the ball more energy and will increase the number of times it bounces.
What does it mean for waves to be absorbed? Make sure to include energy in your explanation.
Answer:
The energy of a wave is transferred to the material it encounters. Ex.) When the ocean waves meet the shoreline, most of their energy is absorbed by the shore.
Explanation:
Ex.) When the ocean waves meet the shoreline, most of their energy is absorbed by the shore.
Wave absorption takes place when a wave transfers its energy to the atoms and molecules of the medium it comes in contact with.
What does it mean for a wave to be absorbed ?When a wave is absorbed, matter absorbs energy from the wave, lowering its amplitude. When a sound wave strikes foam padding, for example, the energy passes through the material and is sometimes converted into heat or other forms of energy.
The energy of a wave is transferred to the particles in the surface when it is absorbed by a surface. This usually causes the particles' internal energy to increase.
Some wavelengths or colors of light are absorbed when white light shines on an opaque object.
Thus, Wave absorption takes place when a wave transfers its energy to the atoms and molecules of the medium it comes in contact with.

Answer:
number (12 is c) (13 is 5) (14 is 5)
Explanation:
Answer:
12:B 13: 5 m/s 14: 5 m/s
Explanation:
12: this is a position vs time graph, and that worded description matches the graph because the slope of a p vs t graph is the velocity
13: again, the slope of a position vs time graph is the velocity. 10m/2s = 5 meters a second or m/s
14: same thing. the object travels 30 m in 6 s so 30/6=5 m/s
