Answer:
the speed of light in glass is 1.52 times smaller than in a vacuum
Explanation:
The speed of light in a medium is given by:
where
c is the speed of light in a vacuum
n is the refractive index of the medium, which is a number always greater than 1.0
From the formula, we see therefore that when light enters a medium, its speed decreases.
In particular, for glass the index of refraction is
n = 1.52
Therefore, this means that the speed of light in glass is 1.52 times smaller than in a vacuum.
Work=Fdcos(theta) so (10000)(45.0)cos(12.5 degrees) = 440000 J
Answer:
According to Democritus' atomic theory, the universe and all matter obey the following principles: Everything is composed of “atoms”, which are physically, but not geometrically, indivisible. Between atoms, there lies empty space. Atoms are indestructible.
Explanation:
Answer:
Abiotic - sun Biotic- Plants
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources.
Explanation:
Abiotic means non living so the sun is non living. The sun gives us warmth and the ability to survive
Biotic means alive or living- plants are living and give off oxygen and take in carbon to help us live umm ok
There is no similarity between the two situations aside from the fact that the earth will still be under the gravitational pull of the sun. Whatever the position of the earth around the sun, the gravity never looses its connection to it. But there are some incidents that might happen to the life forms of the earth if incase the earth stops rotating, all life forms not rooted on the ground will be pulled of moving eastward at 1000mph. Aside from that, an entire earth day will be equivalent to one year. The sun will also rise on the west and sets on the east. The earth's centrifugal force will also be changed causing the earth's structure to bulge. These things will happen if incase the earth stops rotating.
