Answer:
Star A is 3.343 times hotter than star B.
Explanation:
It is known that the luminosity of a star is proportional to its effective temperature to the 4th power. This means that the ratio between the brightness of stars A and B is equal to the ratio between their temperatures to the 4th power:
![125=T^4\\T=\sqrt[4]{125}\\T=3.343](https://tex.z-dn.net/?f=125%3DT%5E4%5C%5CT%3D%5Csqrt%5B4%5D%7B125%7D%5C%5CT%3D3.343)
Star A is 3.343 times hotter than star B.
Answer:
The Middle Colonies like New York and Pennsylvania had more cities because they were the most populated, and the most cosmpolitan. Industry, and trade were promoted in these colonies, as well as a diverse population because there was a higher degree of tolerance for other religious denominatios. Maryland for example, was a haven for Catholics in Colonial America.
Southern Colonies like Virginia or South Carolina were the most rural. This was because the economy of these colonies was based on agriculture, either in the form of large cash crop plantations that were worked by African American slaves, or in the form of small, subsistance farms in the backcountry (Appalachia), which were settled by poor Europeans, mainly coming from Scotland and Northern Ireland (Ulster).
Answer:
The continents have moved over time.
Explanation:
Fossils are one of the best indicators of Earth's history. They are great information about how organisms looked, lived, evolved, but also they show what was the climate like, the geography, and even Earth's processes. The fossils are actually used as one of the best evidence for the theory of plate tectonics.
The reason why fossils are so important for the theory of plate tectonics is that there are numerous species of organisms that have been discovered in different continents that have no connection at present whatsoever and are far away from each other. It is practically impossible for exactly the same organisms to evolve in different places, especially not in different environments. In multiple specimens of a single species are left in several different environments, if they survive, they will all evolve different characteristics, not remain the same. This proves that continents that now are not connected, in the past were actually merged together, but because of divergent plate boundaries have moved away from each other.
