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?

Answers

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.

If there are 20 waves in a 5-second time frame, what is the frequency?

Answers

Your answer would be 0.20 Hz

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.

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.

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

Answers

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.
