What is the color of the stars with the highest temperature

Answers

The color of a star is a function of its temperature.

For example:

1- If a star looks red that means that its temperature is approximately 2,500 Kelvin.
2- Our Sun, which actually looks white from space, measures about 6,000 Kelvin.
3- The hotter the star, the further up the spectrum you go. The hottest stars are the blue ones. A star appears blue once its surface temperature goes above 10,000 Kelvin or so, a star will appear blue to our eyes.

Just a fact: The hottest star known in the Universe are the blue hypergiant stars. These are stars with more than 100 times mass of the Sun. One of the best known examples is ''Eta Carinae'' that is located about 7,500 light-years from the Sun. ''Eta Carinae'' could be as large as 180 times the radius of the Sun, and its surface is 36,000 - 40,000 Kelvin.

Well hope i helped! I f you need anything more ask me! And think about Eta Carinae is super hot, like wow, 40,000 Kelvin is like 79,000 degrees F. So thats hot, like no joke is super hot.

What is the ground state shorthand notation for iron (Fe)?

Answers

Answer:For Fe

Z=26

Explanation:

1s2 2s2 2p6 3s2 3p6 4s2 3d6

Are there 26 electrons here? Why should there be 26?

So going back to the inert gas, argon ( Z=18 ), we get

[Ar] 4s2 3d6

Answers

The term describes the role of fungi in this food chain is decomposer. Therefore, option B is correct.

What is the role of fungi ?

In forest, fungi are known as the important decomposers. Some kinds of fungi, such as mushrooms, look like plants. But fungi do not have chlorophyll, it is the pigment that green plants use to make their own food with the help of sunlight.

Fungi have the ability to convert nutrients so that they are available to plants. Some fungi are decomposers, which means they decompose plant and animal waste, cycling nutrients and increasing their availability in the soil.

Decomposers like fungi and bacteria are complete the food chain. They turn organic wastes that are decaying plants into the inorganic materials, such as nutrient-rich soil.

Thus, option B is correct.
