We can use the kinematic equation
where Vf is what we are looking for
Vi is 0 since we start from rest
a is acceleration
and d is the distance
we get
(Vf)^2 = (0)^2 + 2*(2)*(500)
(Vf)^2 = 2000
Vf = about 44.721
or 44.7 m/s [if you are rounding this by significant figures]
Because the polar regions receive low-angle insolation.
Insolation is the amount of solar radiation received by a given area. The Sun is always low on the horizon. The low Sun angle makes the beam of solar radiation to travel a longer distance from upper troposphere to reach earth's surface as compared to when it is directly overhead. In this case, the radiations are scattered and reflected more by the atmosphere and spread over a larger area. Thus, the intensity of solar radiation is very less at polar regions than near the equatorial region. This is the reason of very cold climates at polar regions.
The heat is transferred to one material to another, however insulators minimize that transfer, keeping it in the area, warming it.
Answer:
4.7 is 10 as much as the number 0.47.
If you multiply 0.47 x 10 it will equal 4.7
Explanation:
Answer:
Explanation: The two main types of nuclear power are nuclear fusion and fission. Nuclear fission is used in nuclear power plants to create elements. Nuclear fission works by having a stray neutron collide with a nucleus. When this happens, it breaks the nucleus up, and another nuclei collides with another nucleus. A chain reaction occurs as this process continues. I personally think this type of nuclear power is dangerous because the result is radioactive byproducts. Also, meltdowns can occur in a nuclear power plant as a result of nuclear fission. I think nuclear fusion would be a much safer energy source. It is cheap and practically unlimited. Nuclear fusion occurs when two nuclei fuse together to create a larger nucleus. Nuclear fusion also proves Albert Einstein's equation E=mc2. The element you start out with is greater than the element you end up with after fusion occurs. This is due to some of the matter actually being converted into energy, which agrees with Einstein's equation. I think nuclear fusion is a safer energy source because it does not create radioactive byproducts that can be potentially harmful. Nuclear fusion, however, is not understood that well by scientists. As a result, we continue to use nuclear fission because we know how to use it. Until scientists fully understand nuclear fusion, scientists will continue to use nuclear fission for energy sources.
