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.

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.

Surface temperature of Sun is

Surface temperature of Sun is

Luminosity of Rigel star in Orion constellation is 17, 000 times that of our sun. If the surface temperature of the sun is 6000 K, calculate the temperature of the star.

The radiation emitted by a star A is 10000 times that of the sun. If the surface temperature of the sun and star A are 6000 K and 2000 K respectively. The ratio of the radii of the star A and the sun is:

The radiation emitted by a star A is 1000 times that of the sun. If the surface temperature of the sun and star A are 6000 K and 2000 K respectively. The ratio of the radii of the star A and the sun is:
