most likely A, because rock doesnt just appear, it takes a while to form, therefore the rock layers could have taken thousands of years to form with fish dying in between
Answer:
When air temperature is higher, the weather is warmer.
Answer:
<em>The wave will be travelling in the y-axis</em>
Explanation:
An e-m wave has a spatially varying electric field that is always associated with a magnetic field that changes over time and vice versa. The electric field and the magnetic field oscillates perpendicularly to each other, and together form a wave that travels in a perpendicular direction to the magnetic and the electric field in space. The movement of the e-m wave through space is usually away from the source where it is generated. So, if the electric field travels in the z-axis, and the magnetic field travels through along the x-axis, then the e-m wave generated will travel in the y-axis direction.
There are two rules of reflection for the concave mirror:
1)<span>Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection.
2)</span><span>Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.
Also, keep in that for concave mirror center of curvature is 2f.
Using these two rules we can construct the image.
You should always use these two "special" rays, I will mark then 1 and 2 on the picture.
From the picture, we can see that if you place the object between the focus and vertex you get the virtual image.
The answer is: object should be between the focal point and the vertex</span>
It is important for people to learn physics so that they can better understand the basic laws of the universe, and most importantly, so we can look at things with common sense, for you my friend i recommend watching <em>mythbusters</em>, they teach physics and make learning fun they teach you to look at the world with common sense. hope i helped!!! have a good day.
