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

If there were no atmosphere, the average temperature on the surface of earth would be :-

Earth's orbit is an ellipse with eccentricity 0.0167. Thus the earth's distance from the sun and speed as it moves around the sun varles from day-to-day. This means that the length of the solar day is not constant through the year. Assume that the earth's spin axis is normal to its orbital plane and find out the length of the shortest and the longest day. A day should be taken from noon to noon. Does this explain variation of length of the day during the year?

The largest and the shortest distance of the earth from the sun are r_1 and r_2 . Its distance from the sun when it is at pependicular to the major-axis of the orbit drawn from the sun is .........

The largest and the shortest distance of the earth from the sun are r_(1) and r_(2) , its distance from the sun when it is at the perpendicular to the major axis of the orbit drawn from the sun

The moon's distance from the earth is 360000 km and its diameter subtends an angle of 42' at the eye of the observer. The diameter of the moon in kilometers is

A small body of superdense material, whose mass is twice the mass of the earth but whose size is very small compared to the size of the earth, starts form rest at a height H lt lt R above the earth's surface, and reaches the earth's surface in time t . then t is equal to

In the Rutherford’s nuclear model of the atom, the nucleus (radius about 10^(–15) m) is analogous to the sun about which the electron move in orbit (radius ~~ 10^(–10) m) like the earth orbits around the sun. If the dimensions of the solar system had the same proportions as those of the atom, would the earth be closer to or farther away from the sun than actually it is? The radius of earth’s orbit is about 1.5 xx 10^(11) m. The radius of sun is taken as 7 xx 10^8 m .

The diameter of the sun subtends an angle of 0.5^(@) at the pole of the concave mirror. The radius of curvature of the mirror is 1.5 m. Find the diameter of the image of the sun. Consider the distance of sun from the mirror infinite
