Why does a star change over time?
A star changes over time as it ages because its internal composition changes as nuclear fusion reaction in the star's core convert one element into another

What information is needed to plot a star on the H-R diagram?
You need to know the luminosity and temperature of star in order to plot it on the HR diagram.
What type of star is the hottest on the H R diagram?
An O type star.
What is the relationship between the sizes of a star to its temperature brightness and its position in H-R diagram?
i hate you !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
Why will the Polaris not always be the pole star?
That's because of precession. In other words, the position of Earth's axis of rotation in space changes over time.
Where is the neutron star on the h-r diagram?
Because of it's initial high temperature it is not even on the diagram, but far off to the left of the diagram.
How does the chemical content of a star affect its position on the H-R Diagram?
becase it so green you can win a game at game stop

What does a H R Diagram compare?
The H-R diagram compares a star's surface temperature to its absolute brightness.
Why does a star change over time?
A star changes over time as it ages because its internal composition changes as nuclear fusion reaction in the star's core convert one element into another
Why phase current is equal to line current in star connection?
Because it is the same current, as you can determine by examining a circuit diagram of a star connection.
What is the brightest star on the Hr diagram?
i don't know about the hr diagram but the brightest star known is r136a1
Is a star living?
Kind of because it changes and other stuff but it is not a organism.
What are the evidences that earth revolves around the sun?
Several pieces of evidence. For example, the parallax: the apparent position of a nearby star changes slightly, because of the change in Earth's position. That is, its position now will not be exactly the same as its position 6 months later, when Earth is on the other side of its orbit. This is used to calculate the distance of nearby stars.
