Varying what causes wind?
temperature or magnitude
Spica and Rigel have similar surface temperatures but their absolute magnitudes are different why is this?
Spica has a surface temperature of 22,400K and an absolute magnitude of -3.55Rigel has a surface temperature of 11,000K and an absolute magnitude of -6.7So the question is incorrect.
What are stars with low magnitude low temperature and low absolute magnitude?
This probably refers to red dwarves. The apparent magnitude depends on the distance, as well as the absolute magnitude, but even the closest red dwarves can't be seen with the naked eye.
Examples of scalar quantities?
length,area,volume,speed,mass,density,pressure,temperature,energy,entropy work,power & charge.
How are the brightness and temperature related?
brightness and temperature are both related because brightness is actually tempature. However the system has become more refined. Instead of just looking at the star and determining magnitude one or magnitude two, an astronomer measures the brightness of the star using a device called a photometer. The photometer counts the number of photons coming from the star. This photon count is then compared to the photon count from a star whose magnitude is known. An accurate magnitude can then be calculated.
What is true about the absolute magnitude and temperature of supergiant stars?
Absolute magnitude: they are extremely bright. Temperature: their surface temperature is fairly low.

How does a star's temperature affect its absolute magnitude?
The absolute magnitude of a start will increase both:* If its surface temperature increases, and * If its diameter increases.

What would be the absolute magnitude and color of a main sequence star with a luminosity of 100?
Absolute magnitude = -0.5Colour would depend on it's temperature.
What are stars with low magnitude low temperature and low absolute magnitude?
This probably refers to red dwarves. The apparent magnitude depends on the distance, as well as the absolute magnitude, but even the closest red dwarves can't be seen with the naked eye.
What are the main components of the h-r diagram?
Surface temperature and Absolute magnitude
What is a graph that shows the relatonship between stars surface temperature and its absolute magnitude?
That is called the Hertzsprung-Russell or HR diagram and each star occupies a point. The horizontal axis is temperature and the vertical axis is the absolute magnitude.
Is temperature vector or scalar?
Temperature is a scalar quantity. It has magnitude but not direction.
What three factors determine the magnitude of star?
The apparent magnitude of a star is dependent on the star's size, temperature and distance from where it is observed. An absolute magnitude is determined by the same three factors, but the distance is fixed at 10 parsecs.
What happens when the temperature-of lava increases?
When the temperature of lava increases, its viscosity will decrease. Viscosity is a measure of the magnitude of internal friction of a substance.
