Calculate angular momentum to Neptune about the sun. Given, mass of neptune `= 10^(12) m` and period of revolution around the sun` = 5 xx 10^(9)s`.

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 .

The distance of planet Jupiter from the Sun is 5.2 times that of the earth. Find the period of revolution of Jupiter around the Sun.

The distance of the planet Jupiter from the Sun is 5.2 times that of the Earth. Find the period of Jupiter's revolution around the Sun.

Calculate the period of revolution of Neptune around the sun, given that diameter of its orbit is 30 times the diameter of earth's orbit around the sun, both orbits being assumed to be circular.

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.

Calculate the period of revolution of the neptune around the sun, given that diameter of its orbit is 30 times the diameter of the earth's orbit around the sun. Assume both the orbits to he circular.

A comet is in highly elliptical orbit around the Sun. The period of the comet's orbit is 90 days. Some statements are given regarding the collision between the comet and the earth. Mark the correct statement. [Mass of the Sun = 2 xx 10^(30) kg , mean distance between the earth and the Sun = 1.5 xx 10^(11)m .]
