Which describes why people on earth can see light from the stars in the sky that are so far away? A. Light from the stars is visible light and travels in longitudinal waves. Longitudinal waves require a medium to travel; therefore, light is reflected off particles of matter in space to be seen on the earth. B. Light from the stars is visible light and travels as surface to surface waves. Surface waves require a medium to travel; therefore, light travels from the surface of the star to the surface of the earth. C. Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves require a medium to travel; therefore, light is reflected off particles of matter in space to be seen on the earth. D. Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves do not require a medium to travel; therefore, light travels through the vacuum of space to be seen on the earth. I think it is D

What happens to the kinetic energy of a snowball as it rolls and gains mass.

Answers

If it is GAINING mass, the kinetic energy increases because it's still moving. If it stopped, it would then become potential energy.

Which material will refract light the least? n = 1.72 n = 2.34 n = 1.58 n = 1.92 I think the answer is n = 1.58 but I need to know why a low index of refraction makes light move slower because I thought a low n would make light move faster in the medium.

Answers

Yes you're right. The smaller 'n' is, the faster the speed of light in THAT medium.
In empty space vacuum, where the speed of light is fastest, n=1 exactly. In any material medium, 'n' is bigger than 1, and the bigger it is, the slower the speed of light in that medium.
The amount of refraction depends on the CHANGE of speed at the boundary. So when light goes from air or vacuum into, say, the 2.34, there's a big change of speed, and more refraction. But from space or air into 1.58, less change of speed, and less refraction.
If the light is going from a block of 1.58 into a block of 1.72, then not much refraction, because not much CHANGE in speed.

Definition of transalatory motion

Answers

Translational motion is the motion by which a body shifts from one point in space to another. One example of translational motion is the the motion of a bullet fired from a gun. An object has a rectilinear motion when it moves along a straight line. Hope this helps! :)

Answer:

Translational motion is the motion of body where body moves in the linear path. It is the motion in which all points of a moving body move uniformly in the same line or direction.

Yes at the tem of 500

Explain why the temperature for freezing point and boiling point are the same.

Answers

We have to wonder what substance you're working with. Under normal, human environmental conditions, there are almost no substances that freeze and boil at the same temperature.

However, EVERY substance has SOME temperature, at some pressure, at which it "sublimes" ... passing directly from solid to gas, or from gas to solid, without existing in liquid form in between. Even water does that, if the conditions are right.

If you are referring to the rules of Celsius, that applies. Since the freezing point of water in Celsius is 0 degrees and the boiling point of water is 100 degrees, it can be said that the to share an equal distance from each other. (100-100=0 and 0+100= 100) You would have to gain or lose 100 so they both gave the same distance from each other.

Timmy placed a horseshoe magnet on his desk. He then sprinkled some iron filings around the magnet. In the images below, the poles of the horseshoe magnet are shown in white. Which of the following images best shows how the iron filings arranged themselves?

Answers

Answer:

The 3rd image

Explanation:

A magnet has 2 poles, north and south. Magnetic fields originate from the north pole and the move to the south pole.

They are concentrated at the poles where they are strongest.

The best image that demonstrates the arrangement of the magnetic fields is the 3rd image.

Answer:

The 3rd image
