Assume earth is rotating around sun in circular path. Does sun do any work on earth? explain.

Assume that the earth moves around the sun in a circular orbit of radius R and there exists a planet which also moves around the sun in a circular orbit with an angular speed twice as large as that of the earth. The radius of the orbit of the planet is

Assuming that the earth revolves around the sun in a circular orbit, the line joining the earth and the centre of its orbit covers………area. [Fill in the blanks]

The earth is revolving round the sun. Is it an example of a simple harmonic motion? Explain.

The earth is revolving round the sun. Is it an example of a simple Harmonic Motion? Explain.

The earth rotates around the sun in a circular orbit of radius R. Calculate the orbital speed of rotation of the earth around the sun. Also find the time period of rotation. Take the mass of the earth =m, mass of the sum =M.

Select the correct option stating the reason for your choice. A satellite is revolving around the earth in a circular path. It has (i) constant velocity (ii) constant acceleration (iii) variable acceleration.

Assuming that the earth moves around the sun in a circular orbit, find the orbital speed (in km*h^(-1) ) and the orbital angular velocity of the earth. The radius of the earth's orbit =1.5xx10^8km .

Assuming that the moon moves around the earth in a circular orbit of radius 3.8xx10^5 km in 27 days and the earth moves around the sun in a circular orbit of radius of radius 1.5xx10^8 km in 365 days, find the ratio of the masses of the sun and the earth.
