<span>Scientists have obtained most of this information from natural geological activity.
</span>S-waves and p-waves are seismic waves- the waves of energy that travel through the Earth as a result of an earthquake .Both P- and S-waves travel easily through solids, but S-waves cannot pass through liquids, and they cannot pass through the outer core. Scientists know that Earth’s outer core is liquid because s-waves are not able to pass through it.<span> When an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive.
</span>So, one of the reasons <span>why scientists believe the outer core is liquid is the s-wave shadow zone.</span>
Answer:
The eyes collect and focus visible light. The lens and other structures of the eye work together to focus an image on the retina. ... Cells in the retina change the image to electrical signals that travel to the brain through the optic nerve. The brain interprets the electrical signals as shape, color, and brightness.
Explanation:
Answer:
The person must be located in the Equator Line. The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
Explanation:
Physically speaking, the centripetal acceleration (
), measured in meters per square second, experienced by a person is defined by the following expression:
(1)
Where:
- Angular speed of the Earth, measured in radians per second.
- Distance perpendicular to the rotation axis, measured in meters.
Since rotation axis passes through poles and distance described above is directly proportional to centripetal acceleration. The person must be located in the Equator Line, which is equivalent to the radius of the planet.
In addition, the angular speed of the Earth can be calculated in terms of its period (
), measured in seconds:
(2)
If we know that 
and 
, then the maximum centripetal acceleration experienced by a person is:
The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
Answer:
What could have possibly turned the iron fence into a different texture and color. What chemical reaction has taken place in order to change the texture and color of the iron fence? If you live in a wealthy neighborhood, then chances are, they might think it looks lazy. Weather, Rainstorms, and high humidity cause iron fences to rust. You can probably repaint the fence a different color. As long as your friends aren't harsh with you, I don't think they'll think it's ugly. I would prefer a wooden fence and then repaint it from there.
Explanation:
I hope this helps :)
