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..

Numerical Value of Acceleration due to Gravity on Earth
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..

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..
Gravitational potential energy of a mass m at a height h above the surface of the Earth
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..
The Earth's Crust
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..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
