Answer:
The angle of refraction is option b: 17°.
Explanation:
We can find the angle of refraction by using Snell's law:
![n_{1}sin(\theta_{1}) = n_{2}sin(\theta_{2})](https://tex.z-dn.net/?f=%20n_%7B1%7Dsin%28%5Ctheta_%7B1%7D%29%20%3D%20n_%7B2%7Dsin%28%5Ctheta_%7B2%7D%29%20)
Where:
n₁: is the index of refraction of the medium 1 (air) = 1.0003
n₂: is the index of refraction of the medium 2 (diamond) = 2.42
θ₁: is the angle of incidence = 45°
θ₂: is the angle of refraction =?
Hence, the angle of refraction is:
![sin(\theta_{2}) = \frac{n_{1}sin(\theta_{1})}{n_{2}} = \frac{1.0003*sin(45)}{2.42} = 0.2922](https://tex.z-dn.net/?f=%20sin%28%5Ctheta_%7B2%7D%29%20%3D%20%5Cfrac%7Bn_%7B1%7Dsin%28%5Ctheta_%7B1%7D%29%7D%7Bn_%7B2%7D%7D%20%3D%20%5Cfrac%7B1.0003%2Asin%2845%29%7D%7B2.42%7D%20%3D%200.2922%20)
![\theta_{2} = 17 ^{\circ}](https://tex.z-dn.net/?f=%20%5Ctheta_%7B2%7D%20%3D%2017%20%5E%7B%5Ccirc%7D%20)
Therefore, the correct option is b: 17°.

Answer:
<em>Vernal equinox, autumnal equinox, march equinox, September equinox, northward equinox and southward equinox </em><em>are the names for the equinoxes.
</em>
<u>Explanation:
</u>
There are different names which are named depending on the <em>month of the year when these equinox occurs and depends upon direction of motion of the sun</em>.<em> Equinox is a point where day time and night time have exactly equal length of time.</em>
Equinox occurs <em>twice</em> in a year and this occurs when <em>earth's equator passes through the sun</em>. We can say that equinox occurs when the sun’s center is directly above the equator.
That's true.
Magnets attract some metals such as iron, nickel, etc.

Answer:
One observation would be the change in odor when observing the logs burning in a campfire and because of that a inference could be because a change in odor is occurring, a chemical change is happening to the logs (combustion).
A second observation would be that the wood being burned gave off smoke at first but then stopped and because of that a inference would be that the compound that were being burned creating the smoke was all evaporated from the wood.
Answer:
im sure your already past this but it's E.
Explanation:
This is because in this case potential energy is linear to height, which means that the higher the more potential energy.
