The angular diameter of the sun is 1920". If the distance of the sun from the earth is 1.5xx10^(11) m, what is the linear diameter of the sun ?
The distance of the Earth from the Sun is
The mean distance of sun from the earth is 1.5xx10^8km . The time taken by light to reach earth from the sun is
A boy is trying to start a fire by focusing sunlight on a piece of paper using an equiconvex lens of focal length 10cm . The diameter of the sun is 1.39xx10^(9)m and its mean distance from the earth is 1.5xx10^(11)m . What is the diameter of the sun's image on the paper ?
The distance of the sun from earth is 1.496xx10^(11)m. If the angular diameter of the sun is 2000'', find the diameter of the sun.
During a total solar eclipse, the disc of the moon almost completely covers the disc of the sun. If the distance of the Sun from the earth= 1.496xx10^(11) m, diameter of the Sun 1.393xx10^(8) m, then calculate the diameter of the moon.
The total luminosity of the sun is 3.9xx10^(26)W . The mean distance of the sun from the earth is 1.496xx10^(11)m . Calculate the value of solar constant.
The earth receives at its surface radiation from the sun at the rate of 1400 Wm^-2. The distance of the centre of the sun from the surface of the earth is 1.5xx10^11 m and the radius of the sun is 7xx10^8m. Treating the sun as a black body, it follows from the above data taht its surface temperature is ......K
