A satellite is moving in an orbit around the earth due to

A comet is moving around the earth in.highly elliptical orbit. Identify the incorrect statement

Assertion: The artifical satellite does not have any fuel but even then it remains orbiting around the earth. Reason: The necessary centripetal force required to move the satellite in an ·orbit around the earth is provided by the gravitational force of attraction between the satellite and the earth.

Two satellites are orbiting around the Earth in circular orbits of the same radius. The mass of satellite A is five times greater than the mass of satellite B. Their periods of revolution are in the ratio

Obtain an expression for the period of a satellite in a circular orbit round the earth OR Show that the square of the period of revolution of satellite is directly proportional to the cube of the orbital radius. OR Show that period of the satellite revolving around the earth depends upon mass of the earth

In a surface tension experiment with a capillary tube water rises upto 0.1 m . If the same experiment is repeated in an artificial satellite, which is revolving around the earth , water will rise in the capillary tube upto a height of :

If a second 's pendulum is placed in a space laboratory orbiting around the earth at a height 3 R, where R is the radius of the earth , then the time period of the pendulum will be

Which fuels can be obtained by microbial processes ? Why is it necessary to increases the use of such fuels ?

Two small satellies move in a circular orbits around the earth, at disatnce r and (r + dr) from the centre of the earth. Their time periods of rotation ate T and T + dT (Delta r lt lt r, DeltaT lt lt T) . Then
