Examine the image of the Hertzsprung-Russell diagram.

The H-R Diagram. The y axis shows Luminosity in solar units increasing in increments of the power of 1 from 10 from bottom to top. The x axis shows Surface Temperature in Kelvin, decreasing from left to right. Supergiants are yellow white, luminosity between 10 superscript 4 solar units and 10 superscript 5 solar units. Main is blue white, luminosity 10 superscript 4. Sequence is blue white, luminosity 10 superscript 3. Giants are red and orange, luminosity between 10 superscript 2 and 10 superscript 3. Sun is yellow, luminosity between 1 and 10. AB Doradus C is red, luminosity 10 superscript negative 3. White Dwarfs are blue, blue white, white, yellow white, and yellow, luminosity from 1 to 10 superscript negative 4.

Which characteristic describes the stars indicated by the arrow in the image?

cool
hot
large
small

Answers

Answer 1

Answer:

The answer is cool.

Explanation:

If you look at the diagram then you can see that the star being pointed to is orange-ish. Red and orange stars are the more cooler ones.

Answer 2

Cool is the characteristic that describes the stars indicated by the arrow in the image. Therefore, the correct option is option A.

What is star?

A star is an extremely bright ball of primarily hydrogen and helium-based gas that is kept together through its own gravity. The star is supported against gravity by nuclear fusion events at its core, which also yield photons, heat, and trace quantities of heavier elements.

The star is created when hydrogen nuclei start to fuse into helium nuclei at a temperature of roughly 10 million K (18 million °F) in the gas. The expanding star's core emits energy through nuclear fusion, which eventually slows the gas cloud's collapse. Cool is the characteristic that describes the stars indicated by the arrow in the image.

Therefore, the correct option is option A.

mention the importance of writing the number in scientific notation​

Answers

Answer:

Scientific Notation was developed in order to easily represent numbers that are either very large or very small. ... As you can see, it could get tedious writing out those numbers repeatedly. So, a system was developed to help represent these numbers in a way that was easy to read and understand: Scientific Notation.
