Calculate the mass of the sun , given that the sistance between the sum and the earth is ` 1.5xx 10^(-11)` m and G = `6.66 xx 10 ^(-11)` SI units and taken a year = 365 days .

Estimate the mass of the sun, assuning the orbit of Earth round the sun to be a circule. The disatnce between the sun and the Earth is 1.49 xx 10^(11) m , and G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) .

If the distance between the sun and the earth is 1.5xx10^(11) m and velocity of light is 3xx10^(8) m//s , then the time taken by a light ray to reach the earth from the sun is

Estimate the mass of the sun, assuming the orbit of the earth round the sun to be a circle. The distance between the sun and earth is 1.49 xx 10^(11) m and G = 6.66 × 10^(-11) Nm^(2)//kg^(2) .

Calculate the mass of the sun if the mean orbital radius of Jupiter around the sun is 7.8 xx 10^(11) m . Take G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) Time period of revolution = 12 years according to earth

Calculate the mass of sum if the mean radius of the earth's orbit is 1.5xx10^(8)km and G=6.67xx10^(-11)Nxxm^(2)//kg^(2)

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 ?

If the mass of the sun is 2 xx 10^(30) kg , the distance of the earth from the sun is 1.5 xx 10^(11) m and period of revolution of the earth around the sun is one year ( = 365.3 days ) , calculate the value of gravitational constant .

How far from earth must a body be along a line towards the sun so that the sun's gravitational pull on it balances that of the earth . Distance between sun and earth's centre is 1.5 xx 10^(10) km . Mass of the sun is 3.24 xx 10^(5) times mass of the earth .

The energy from the sun reaches just outside the earth's atmoshphere at a rate of 1400 W m^(-2) . The distance between the sun and the earth is 1.5 xx 10^(11) m . (a) Calculate the rate at which the sum is losing its mass. (b) How long will the sun last assuming a constant decay at this rate? The present mass of the sun is 2 xx 10^(30) kg
