Which of the following factors influence ocean currents ? 1. Rotation of the Earth. 2. Air pressure and wind. 3. Ocean water density. 4. Revolution of the Earth. Select the correct answer using the code given below:

Radius of a geostationary satellite revolving round the earth is 'r'. Then period of revolution of another satellite revolving in an orbit of radius r/2 is

Taking the rotation and revolution of the earth into account, does a tree move faster during day or during night?

The period of revolution of an earth's satellite close to the surface of the earth is 60 minute. The period of another the earth's satellite in an orbit at a distance of three times earth's radius from its surface will be (in minutes)

Find the acceleration of a particle placed on the surface of the earth at the equator, due to the earth rotation. The radius of earth is 6400 km and time period of revolution of the earth about its axis is 24 h.
