Assume that the earth goes round the sun in a circular orbit with a constant speed of 30 km/s

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 .

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

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 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]

r denotes the distance between the sun and the earth. Assume that the earth moves around the sun in a circular orbit of radius r. The angular momentum of the earth around the sun is proportional to
