How is energy transformed?

Answer:

Sound travels the slowest through gases because the particles of a gas are closer together.

Explanation:

Because the molecules of gases are farther apart which makes it slower vs  solids whereas their molecules are closer together which makes it faster

Switch

Explanation:

since when you flick the switch up its stops electricity

Answer: The frequency of a wave is inversely proportional to its wavelength.

Explanation:  That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.

It captures images but does not preserve them.

Answer:

Force

If you're taking classical physics, simply stated, a force is a push or a pull of some sort. But there is one other very important thing to understand about Force. A true Force is always an interaction (at least from a classical perspective). That means that forces always come in pairs. This is stated in Newton's Third Law (equal and opposite forces). Every action must have a reaction. This is required for all true forces. Another consequence of this is that force is a vector, meaning it has a magnitude and a direction. The action and reaction will always be opposite in direction.

A lot of people will say F=ma. This is true. However, it is important to keep in mind that this definition is a calculational tool. It is more precise to say the Sum of all forces=ma. The point is that ma is not a force. Forces are things like weight, tension, normal, friction, gravity, electrostatic, magnetic, and various other applied forces. The sum of forces on an object equals the product of its mass times its acceleration.

It is important to keep in mind that the force is on the object that accelerates. Another way to state this is that objects cannot accelerate themselves. You cannot push yourself back (or forwards). But if you push a heavy object like a desk forwards, then the desk can push you back.

Energy

There are many kinds of energy. There are two important things to know.

Energy is the ability to do work. It doesn't mean work is being done, but that work can be done. (So you can see there is an intimate relationship between work and energy).

Energy is conserved. That means the total amount of energy is always constant. If the energy is a system changes somehow, that means some work was done in order to move the energy from one system to another.

Energy is also a scalar (given that Work is a scalar).

Answer:

In the attached link is the answer.

Explanation:

Answer:

Global knowledge is information that is widely accepted and been proven as the truth. It is information that may not necessarily have a source because it is common knowledge and not easily attributed to a certain source. Personal ideas are original to the author and may not be widely accepted. It is important to give credit to others by citing their work to acknowledge that this is not your own findings but rather someone else's. It is plagiarism to use someone else's work as your own without giving credit to their work. -W0lf93

Answer:

Evaporation is the process by which water changes from a liquid to a gas or vapor.

Questions are labeled during my explanation :D

Explanation:

1a. 5

b. 14

c. 24.666666666667 (you can round it to 25)

d. 30

e. 36.666666666667 (you can round this to 37)

2. The angle if refraction is always less than the angle of incidence as shown in the table. If you were to calculate the averages of all 3 test, it would still be smaller than the angle of incidence.

3. The angle of refraction is always less than the angle of incidence because the light ray must be moving from a optical density than air hence the light ray could seem bended. This is because the the speed of a wave is determined by the medium through it is passing. When light speeds up as it passes from one material to another, the angle of refraction tends to be larger than the angle of incidence. An example of this would be when light passes from water to air or glass to water. This change also makes the image look shifted to the side.

omgg hope you found this helpful it feel awesome to help others but now imma catch some sleep its nearly 1 am here. Have a great day!!!! <33

Answer:

O clouds of dust and gas

Explanation:

Answer:

The electricity that causes the light bulb to light in this activity is coming from the battery. The wire provides a conductive path for the electricity. But this information is not helpful in terms of understanding how the battery works.

Explanation:

Answer:

The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down. The steeper the slope of the line the greater the acceleration. If the line slopes upward from left to right, this means the object is speeding up.

Explanation:

Answer:

It's basically the intensity and frequency of going up and down.

Explanation:

The mouse, for example, isn't doing it very high, but is doing it pretty quick.
