The luminousity of a star is 10,000 times that of the sun and its surface temperature is `3000K`. Assuming the surface of temperature of the sun to be `6000K`, compare the radius of the star with that of the sun.

The luminousity of a star is 10000 times that of the sun. if the surface temperature of the sun is 6000 K, then the surface temperature of the star is

Luminosity of a distant star is 16000 times that of the Sun. If the surface temperature of the Sun is 5890 K, then find the surface temperature of the star.

Surface temperature of Sun is

Surface temperature of Sun is

The luminosity of the Rigel star is 17000 times that of the sun. Assume both to be perfectly back bodies. If the surface temperature of the sun 6000 K, then the temperature of the star is around ("Take "17000^(1//4)=11.4)

The luminosity of the Rigel star is 17000 times that of the sun. Assume both to be perfectly back bodies. If the surface temperature of the sun 6000 K, then the temperature of the star is around ("Take "17000^(1//4)=11.4)

The radiation emitted by a star A is 10,000 times that of the sun. If the surface temperatures of the sun and the star A are 6000 K and 2000 K respectively, the ratio of the radii of the star A and the sun is
