The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K. In the inner solar system, only substances with very high melting points would have remained solid. All the rest would have vaoprized. So the inner solar system objects are made of iron, silicon, magnesium, sulfer, aluminum, calcium and nickel. Many of these were present in compounds with oxygen. There were relatively few elements of any other kind in a solid state to form the inner planets. The inner planets are much smaller than the outer planets and because of this have relatively low gravity and were not able to attract large amounts of gas to their atmospheres. In the outer regions of the solar system where it was cooler, other elements like water and methane did not vaporize and were able to form the giant planets. These planets were more massive than the inner planets and were able to attract large amounts of hydrogen and helium, which is why they are composed mainly of hydrogen and helium, the most abundant elements in the solar system, and in the universe

Explanation:
I want to say option B - Both forces can act without objects touching.
Answer: 0.125
Explanation:
Given that the
Object height U = 24.8 cm
Image height V = 3.09 cm
Magnification M is the ratio of the image height to the object height. That is, divide the given image height by the given object height.
M = V/U
Substitute V and U into the formula above.
M = 3.09/24.8
M = 0.125
Magnification is therefore equal to 0.125 approximately
Answer:
Scientists believe it is the best explanation because it is built on data and observations. The majority of the scientific community voted on this theory over other possible explanations. It is the best explanation because it supports the beliefs and opinions of most scientists.
