Is diffusion of gases affected by the gravitational pull of the earth ?

What is the torque exerted by the gravitational force of sun on the earth ? Explain.

The mass of moon 1% of mass of earth. The ratio of gravitational pull of earth on moon and that of moon on earth will be

At what angle with the horizontal should a projectile be fired with the escape velocity to enable it escape from gravitational pull of the earth ?

A satellite is moving with a constant speed 'V' in a circular orbit about the earth. An object of mass 'm' is ejected from the satellite such that it just escapes form the gravitational pull of the earth. At the tme of its ejection, the kinetic energy of the object is

A research satellite of mass 200 kg circles the earth in an orbit of average radius 3 R//2 , where R is the radius of the earth. Assuming the gravitational pull on the mass of 1 kg on the earth's surface to be 10 N , the pull on the satellite will be a) 1212 N b) 889 N c) 1280 N d) 960 N

Assertion: The length of the day is slowly increasing. Reason: The dominant effect causing a slowdown in the rotation of the earth is the gravitational pull of other planets in the solar system.

A body is projected upwards with a velocity of 4 xx 11.2 "km s"^(-1) from the surface of earth.What will be the velocity of the body when it escapes from the gravitational pull of earth ?

If the ratio of the rates of diffusion of two gases A and B is 4:1 the ratio of their density is

A satellite orbiting close to the surface of earth does not fall down becouse the gravitational pull of earth
