mass of the earth radius of the earth

Earth is the only planet in our solar system, which is surrounded by oxygen, the life giving gas. It is the only planet to have large quantities of water. Earth's atmosphere contains oxygen, nitrogen, carbon dioxide and water vapour. Earth Earth is a medium s..

In outward appearance, the earth is a nearly spherical ball with a radius of 6350 kilometers. Internally, the earth consists of three major layer..

The value of acceleration due to gravity on Earth is 9.8 m/s 2 . This means that when a body falls freely towards the Earth its velocity increases at the rate o..

Gravitational Potential Energy Near the Surface of Earth - As we go higher above the surface of the Earth, the value of acceleration due to gravity decreases. But for those heights which are very small when compared to the radius of the Earth, g (and hence mg..

The method used in the binary star system can be also used for planet-satellite binary system. This is possible because the planet and the satellite also revolve around a common centre of mass...

Most elements are formed due to fusion of simple nuclei to give heavier nuclei i.e., nucleosynthesis or nuclear fusion reactions taking place in the stars. Atoms of these elements began to fall together about six billion years ago to form a system, presently called the solar system. A part of these..

The potential energy of a mass m at a height h is given by the expression Considering P.E. at the surface of the Earth to be n..

During the formation of the Earth, cooling of gaseous mixtures took place and molten earth condensed to form different earth zones or layers. Each layer that formed on top of the other had a definite chemical composition and thus a distinct distribution of elemen..

Continents and ocean basins (land beneath the oceans) are part of a rocky 'skin' that surrounds the main body of the earth. This skin is called the earth's crust. The crust of the earth is like the skin around an orange or an apple. The thickness of the crust varies fr..
