What is energy output from the surface of a star per second?
heat
How many arc seconds away is Vega?
An arc second is a measure of angular separation, not of distance. It is therefore an inappropriate unit for measuring the distance to a star.
How do you measure the angles in a star?
Use a protractor.Use a protractor.Use a protractor.Use a protractor.
What flavor is the yellow can of rock star 2 x energy?
red and yeller
What do you use to measure the angle of a star?
The device that astronomers use to find the angle between the horizon and stars in the sky is called a sextant.
What is a measure of the total energy radiated by the star in one second called?
A star's luminosity is the measure of the total energy radiated by the star in one second.
What is energy output from the surface of a star per second?
heat
Which cell is the energy output of a star?
The energy output of a star is from nuclear fusion. The particles involved with both input and output are atomic (and sub-atomic) in nature not cellular.
What does a stars luminosity measure?
Luminosity is the total amount of energy emitted by a star per second.
How are energy and mass related in a star?
The same as everywhere else. Every mass has associated energy. Every energy has associated mass. Possibly this question is about the energy output of stars. Usually, the more mass a star has the higher its rate of energy output.
Which form of measurement used to measure brightness can be defined as the rate at which the star gives off energy?
Luminosity is defined as the rate at which a star gives off energy. Luminosity can be measured in joules per second or watts.
What is a supernova and what happens?
A supernova is the catastrophic death of a star, characterized by a massive output of energy.
Is an orange star hotter then a yellow star?
The temperature of a yellow star's photo sphere is hotter than that of and orange star. However the total energy output of an orange star may be greater than that of a yellow star.
Define magnitude and intensity?
Magnitude is the measure of the brightness of a star or other celestial body.And, intensity is the measure of energy flux
Do Hotter stars age more slowly then cooler stars?
The surface temperature is not a reliable indicator about how long a star will last. However, the total energy output is. If a star produces a lot of energy, it will burn through its fuel faster.
What factor affects the absolute brightness of a star?
Energy output, as absolute brightness (magnitude) is taken at a standard distance of 10 parsecs.
Are habital zones around stars the same?
Not sure what you mean with "the same", but the habitable zone will presumably be closer to the star, or further away, depending on the star's total energy output.
