The earth has a mass of `6 xx 10^(24) kg` and a radius of `6.4 xx 10^(6)m`. Calcualte the amount of work that must be done to slow down its rotation so that duration of day becomes `30` hrs instead of 24 hours.
Moment of inertia of earth `= (2)/(5)MR^(2)`.

The mass of earth is 6 xx 10^(24)kg and radius is 6400 km. How much amount of work will be done to make the duration of day its 20 hours rather than 24 hours.

The mass of the Earth is 6 xx 10^(24) kg and its radius is 6400 km. Find the acceleration due to gravity on the surface of the Earth.

6xx10^(24)kg : Mass of the Earth :: 6.4xx10^(6)m : ______________.

Calculate the angular momentum of the earth rotating about its own axis. Mass of the earth = 5.98 xx 10^(27) kg, mean radius of the earth =6.37 xx 10^(6)m,M.I of the earth = (2)/(5)MR^(2) .

The mass of the earth is 6.0 xx 10^(24) kg and its radius is 6.4 xx 10^(6) m . How much work will be done in taking a 10 kg body from the surface of the Earth to infinity ? What will be the gravitational potential energy of the body on the Earth's surafce ? G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) .

Complete the aology: 6xx10^24kg: mass of the Earth: : 6.4xx10^6 m______.

If mass of Earth is 6xx10^24 kg, radius of Earth is 6.4 xx 10^6m and the gravitational constant is 6.7 xx10^-(11)Nm^2kg(-2) . Calculate the value of g.

The mass and radius of the earth are 5.975 xx 10^24 kg and 6.37xx 10^6 m respectively. Calculate the average earth's density to correct significant figures. Take pi=3.142 .

The radius of the earth is 6.37 xx 10^(6) m and its mass is 5.975 xx 10^(24) kg . Find the earth's average density to approopriate significant figures.
