Answer:
Explanation:
Basically, Kinetic Molecular Theory says that gas particles are in constant motion and that they show perfectly elastic collisions.
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision.
So the kinetic molecular theory says that gas particles stay moving constantly and don't lose energy when they run into each other.

Valence Electrons: how they increase across the Periodic table (periodic trend), and how they relate to both ionic and covalent bonding?
Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is the lowest energy state of the atom

Electric Charge (guided inquiry)
Purpose: To show how matter becomes charged by induction
Materials: comb, sink with working faucet
Predict: Predict what you think will happen to the charges of the comb and water if the comb comes in contact with the water. Record your hypothesis before following the directions below to carry out the lab experiment. The charges would attract. How and why is what I don’t know.
Directions:
1. Turn on a faucet just enough to allow a thin stream of water to flow.
2. Have a student volunteer-run a comb through his/ her hair a few times.
3. Observe. Tell the student to hold the comb near, but not touching, the stream of water.
4. Answer all questions below in complete sentences, using the R.A.C.E. strategy.
Ask and record your findings: What do you observe? Describe. I observed the stream of water bend toward the comb. I gave the comb electric charge by passing a comb through my sister’s hair and that allowed the comb to bend the stream of water.
Ask and record your findings: What does this indicate (show)? Explain. I
Written response please read all and answer in complete sentences will give BRAINLIEST

Explanation:
Samuel throws a ball into the air 20 meters. It reaches the top of its flight at 2
seconds and hits the ground at 4 seconds. What was the ball's average speed on the
way down?
Answer:
10 m/s
Explanation:
The ball's average speed on the way down is 10 m/s.
How fast does the ball travel when dropped?It would be pretty easy to find the speed of any falling object because they all speed up at the same rate – 3.6 mph every second.
How do you find the average speed of a ball?Average speed can be calculated using the formula v=d/t where the variables are:
1 v is the average speed of the object with units of m/s.
2 d is the total distance or length of the path of the object with units of m.
3 t is the total time taken to cover the path with units of s.
4 Speed cannot have a negative value.

1. How does the structure of a hard-boiled egg compare to the crust, mantle, and core structure of Earth? What do the egg's layers represent? What might the cracks represent?
2. How do Earth's layers compare in composition and properties with the egg's layers?
3. Can an egg be used as a satisfactory model for Earth's lithosphere (plates) and asthenosphere, plus the rest of the mantle, and the core? How? (Hint: Look very carefully under the shell could the membrane there represent the asthenosphere?)
4. Overall, is the cracked egg a useful model for Earth? Why or why not?
5. Unlike the eggshell sections, Earth's plates move relative to one another. A plate may move away from another plate, or it may move toward it. Earthquakes often result from interactions between plates. Predict what other consequences might result from plate motion.
6. Of the several possible non-egg models of Earth, which do you feel is most appropriate? Why?
7. Of the several possible nonegg models of Earth, which do you feel is least appropriate? Why?
Answer:
2. Earth layers compare in egg layer it is hard on the outside
Explanation:
Answer: for 1 and 2 The inside of the earth is layered something like an egg. Both have a thin, brittle shell. The crust of the earth is broken into pieces, like the cracked shell of a hard boiled egg. The mantle of the earth is like the egg white, and the core of the earth lies in the center, like the egg yolk.
for 3 the shell could also be used because you can crack
for 5 a few things that can happen in the result of plate motion there could be Mt formation or volcano formations.

If there are 20 waves in a 5-second time frame, what is the frequency?
If there are 20 waves in a 5-second time frame, the frequency of the wave is 4 Hz.
What are wave and wavelength?A wave is a disturbance that travels through space, carrying energy without transporting matter. Waves can take many forms, such as water waves, sound waves, light waves, and radio waves. In general, waves are characterized by their frequency, wavelength, amplitude, and velocity.
Wavelength is one of the fundamental characteristics of a wave. It is defined as the distance between two consecutive points in a wave that are in phase, that is, they are at the same point in their cycle. For example, in a simple sine wave, the wavelength is the distance between two consecutive peaks or two consecutive troughs.
The symbol used to represent wavelength is the Greek letter lambda (λ). Wavelength is typically measured in meters (m) or some other unit of length. In general, longer wavelengths are associated with lower frequencies and lower energies, while shorter wavelengths are associated with higher frequencies and higher energies.
The relationship between wavelength, frequency, and velocity is given by the formula:
velocity = frequency x wavelength
This formula shows that as the frequency of a wave increases, its wavelength decreases, and vice versa, assuming the velocity remains constant. Similarly, as the wavelength of a wave increases, its frequency decreases, and vice versa, assuming the velocity remains constant.
So, a wave is a disturbance that travels through space carrying energy without transporting matter, while wavelength is the distance between two consecutive points in a wave that are in phase.
Here in the question,
The frequency of a wave is defined as the number of cycles or oscillations that occur in one second. The unit of frequency is hertz (Hz). To calculate the frequency of a wave, we can use the following formula:
Frequency = Number of cycles / Time
In this case, we are given that there are 20 waves in a 5-second time frame. Therefore, the number of cycles is 20, and the time is 5 seconds. Substituting these values into the formula, we get:
Frequency = 20 / 5 = 4 Hz
Therefore, the frequency of the wave is 4 Hz. This means that the wave completes 4 cycles or oscillations in one second.
