<h2>MARK BRAINLIEST</h2>

For this assignment, you will develop several models that show how light waves and mechanical waves are reflected, absorbed, or transmitted through various materials. For each model, you will write a brief description of the interaction between the wave and the material. You will also compose two typewritten paragraphs. The first will compare and contrast light waves interacting with different materials. The second will explain why materials with certain properties are well suited for particular functions.

<h2>Background Information</h2>

A wave is any disturbance that carries energy from one place to another. There are two different types of waves: mechanical and electromagnetic. A mechanical wave carries energy through matter. Energy is transferred through vibrating particles of matter. Examples of mechanical waves include ocean waves, sound waves, and seismic waves. Like a mechanical wave, an electromagnetic wave can also carry energy through matter. However, unlike a mechanical wave, an electromagnetic wave does not need particles of matter to carry energy. Examples of electromagnetic waves include microwaves, visible light, X-rays, and radiation from the Sun.

As the wave interacts with a wall, which kind of wave interaction is shown?

kow [346]

The answer would be a reflection. This is because, the color of an object is actually the wavelengths of the light reflected while all other wavelengths are absorbed. Color, in this case, refers to the different wavelengths of light in the visible light spectrumperceived by our eyes. The physical and chemical composition of matter determines which wavelength (or color) is reflected.

The number line shows the graph of an inequality: which statement explains whether -3.5 can be a value in the shaded region?

guajiro [1.7K]

Yes it can, because −3.5 lies to the left of −0.5.

Yes it can, because −3.5 lies to the right of −0.5.

No it cannot, because −3.5 lies to the left of −0.5.

No it cannot, because −3.5 lies to the right of −0.5.

Yes it can, because −3.5 lies to the left of −0.5.

Answer: Option A.

Explanation:

This option has been chosen because the left of the 0 has been shaded and all the negative values lies on the left of zero. So -3.5 lies to the left of -0.5 and is in the shaded region of the number line.

In a number line, the figure -3.5 lies on the left side compared to the number -0.5 because the higher the value on the negative side of the number line, more left it would be on the number line.

If the total momentum for a system is the same before and after the collision, we say that momentum is conserved. If momentum we

andrew-mc [135]

Answer:

Ratio = 1:1

Explanation:

$P_{i}$ = initial momentum of the system

$P_{f}$ = final momentum of the system

For the momentum to be conserved , final total momentum must be equal to initial total momentum, so we have

$P_{f} = P_{i}$

Dividing both side by $P_{i}$ , we get

$\frac{P_{f}}{P_{i}} = \frac{P_{i}}{P_{i}} \\\frac{P_{f}}{P_{i}} = 1\\$

hence

Ratio = 1

What is the difference between Earth's magnetic and geographic poles? How do navigators take advantage of this?

Triss [41]

Earth's magnetic poles are located near, but not quite exactly at, our planet's geographic poles (the "spin axis" on a globe). Compasses work as direction-finding devices because Earth has a magnetic field. The needle of a compass, itself a small bar magnet, points in the direction of the magnetic pole.
