If temperature of Sun=6000K, radius of Sun is `7.2xx10^(5)Km`, radius of earth=6000 Km & distance
between earth and Sun`=15xx10^(7)`Km. find intensity of light on earth.

The time taken by the earth to complete one revolution around the sun is 3.156 xx 10^(7) s . The distance between the earth and the sun is 1.5 xx 10^(11) m. Find the speed of revolution of the earth.

Distance between sun and earth is 2 xx 10^(8) km, temperature of sun 6000 K, radius of sun 7 xx 10^(5) km, if emmisivity of earth is 0.6 , then find out temperature of earth in thermal equilibrimum.

Distance between sun and earth is 2 xx 10^(8) km, temperature of sun 6000 K, radius of sun 7 xx 10^(5) km, if emmisivity of earth is 0.6 , then find out temperature of earth in thermal equilibrium.

The solar energy received by the Earth persquare metre per minute is 8.315 xx 10^(4)Jm^(-2)min^(-1) . If the radius of the Sun is 7.5 xx 10^(5) km and the distance of the Earth from the Sun is 1.5 xx10^(8) km, calculate the surface temperature of Sun. Assume the Sun as a perfect black body. Given that Stefen constanta sigma = 5.7 xx 10^(-8)Wm^(-2)K^(-4).

The mass of sun is 2xx10^(30) kg and mass of earth is 6xx10^(24) kg. if the distance between the centers of sun and earth is 1.5xx10^(8) km, calculate the force of gravitation between them.

Assume that Solar constant is 1.4 kW//m^(2) , radius of sun is 7 xx 10^(5) km and the distance of earth from centre of sun is 1.5 xx 10^(8) km. Stefan's constant is 5.67 xx 10^(-8) Wm^(2) K^(-4) find the approximate temperature of sun

Assume that Solar constant is 1.4 kW//m^(2) , radius of sun is 7 xx 10^(5) km and the distance of earth from centre of sun is 1.5 xx 10^(8) km. Stefan's constant is 5.67 xx 10^(-8) Wm^(2) K^(-4) find the approximate temperature of sun

The distance between the sun and the Earth is 1.496xx10^(8) km and distance between the Earth and the Moon is 3.84xx10^(8)m . During solar eclipse the Moon comes in between the Earth and the sun. What is the distance between the Moon and the sun at that particlar time?
