What else can I help you with?
If a red star and a white star radiate energy at the same rate can they be the same size If not which must be the largest Why?
They cannot be the same size. The red star must be larger. Red stars are cooler that blue stars and so radiate less energy for a given amount of surface area. In order to radiate the same amount of energy as a blue star, the red star must therefore have a larger surface area.
If a star has a large luminosity and also a low surface temperature then it must have?
If a star has a large luminosity and a low surface temperature, it must have a large surface area to compensate for the low temperature and still emit a high amount of energy. This would make the star a red supergiant, a type of star that is both luminous and cool at the same time.
If a star has a surface temperature of 36000 K at what wavelength will it radiate the most energy?
The wavelength at which a star radiates the most energy is determined by its surface temperature, according to Wien's Law. For a star with a surface temperature of 36000 K, it will radiate the most energy at a wavelength of approximately 80 nm in the ultraviolet part of the spectrum.
What gives a star its energy?
A star gets its energy from nuclear fusion in its core. In this process, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This energy sustains the star and allows it to shine brightly.
What is the surface temperature of alkaid?
Alkaid, a star in the constellation Ursa Major, has a surface temperature of around 7,500 degrees Celsius. It is a hot, blue-white star that emits a significant amount of ultraviolet radiation.

What is energy output from the surface of a star per second?
heat

Which dehumidifiers use the least amount of energy?
the best one would be energy star
How can astronemers infer how hot a star is?
By the amount of energy that they are giving out.
How is it that a star seldom find another star near it?
Stars repel because of the massive amount of energy they put out based on the density of the star.
How is energy generated in a star cores?
Energy in a star's core is generated through nuclear fusion, where hydrogen atoms combine to form helium releasing a massive amount of energy in the process. The extreme temperature and pressure in the core of a star make this fusion process possible, sustaining the star's energy output.

The wavelength at which a star radiates the most energy is determined by its surface temperature, according to Wien's Law. For a star with a surface temperature of 36000 K, it will radiate the most energy at a wavelength of approximately 80 nm in the ultraviolet part of the spectrum.
What additional features do energy star appliances have in contrast with conventional appliances?
Energy star appliances have been improved so much that you can tell the energy cost for instance of the amount of hot water you save and how much money in a years time just by buying energy star.

What prevent the enormous amount of energy released from the fusion reactions at star's core from blowing the star apart?
Gravity. However, sometimes the star IS blown apart.

Alkaid, a star in the constellation Ursa Major, has a surface temperature of around 7,500 degrees Celsius. It is a hot, blue-white star that emits a significant amount of ultraviolet radiation.
