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 an atom?

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Explain what is meant by Pleistocene ice age

Answers

By Pleistocene ice age is meant the glacial periods that appeared in the Pleistocene. The Pleistocene is the first epoch of the Quaternary. It is an epoch when there was a so called ''ice age'' on the Earth, or rather a glacial period. During this ice age the planet had much lower temperatures on a global scale. The climate was also much drier. Lot of ocean water was frozen in the ice sheets that were stretching deep into the North American and Eurasian continents, which resulted in much lower sea levels that today as well. The places further north than 40 degrees of latitude were almost exclusively covered with ice, so life was almost impossible apart from some coastline places.

A runner is traveling around the track below at a constant speed. Is she accelerating? A. Yes, she is accelerating because her speed is constant.


B. Yes, she is accelerating as she turns and changes direction.


C.No, she is not accelerating because there is not an incline to the track.


D.No, she is not accelerating because her speed is constant.

Answers


ANSWER:

D.No, she is not accelerating because her speed is constant.

EXPLANATION:

The rate of change of velocity with respect to time is known as acceleration.

acceleration =change in velocity/time

As she is running at constant speed  and there is no change in velocity so she is not accelerating.
