Impact of Green House Effect
Change in the composition of air due to several human activities has brought about green house effect. Green house effect has brought about following phenomenal changes. The severity of these changes will aggravate further in the next 10-20 years. By 2040, CO 2 level in air is expected to reach a l..
"Remote Sensing"
>Space-based remote sensing is a new technology. It has high potential for applications in nearly all aspects of resource management. India recognized the potential of this technology quite early. India conducted several remote sensing experiments in the late '60s and '70s using airborne sensors an..
Introduction
The term 'natural resources' refers to all the natural things on our earth. It includes everything, that is naturally available and that is not creatable by any human activity. It specifically excludes the materials created by man. Human being and his anthropological history indicate that..
Evolution and Classification
In spite of many evidences, studies and theories, we are still not aware of how the evolution actually occurs. If we go backwards at some point in the history of the earth it would have consisted of only the basic elements, the non-living materials like the air, water, sunlight..
To Determine Molecular Size
A solution of known concentration of oleic acid in alcohol is prepared. Let 1 cm 3 of oleic acid be dissolved in 500 cm 3 of alcohol to get concentration. Let n drops of this solution be poured on a water surface contained in a flat and broad vessel. Oleic acid film is stretched on the ..

The tides are formed due to the gravitational force of attraction between the earth, sun and moon. During high tides sea water is trapped in a reservoir, and released later to drive turbines, which in turn produces electricity. The block diagram given below illustrates the tran..

When scientists started exploring matter, they discovered that the smallest particle of an element that maintains its chemical identity through all chemical and physical changes is called and 'atom'. Just how small these atoms are can be made out if you realize that there are about 60,000,000,000,..

When an object is placed on the surface of a liquid it will either float or sink. This depends upon two forces: The weight W 1 acting vertically downwards, which is due to the gravitational pull of the earth, and Upthrust or buoyant force acting vertically upwards, which is equal t..

Tutor has given me a lot of good advise for my study. They has the package to be the best and the best teachers! they are not just have the teaching skills and understanding the subject matters as well. Thank you.
They made my daughter to quiz herself with flashcards. The strategies that taught,helped her to learn the mulitiplication facts more easily- Slavic
They always come through for me never fails me,great tutors,cant say thank u enough,lets hope we score big on the exams :-) - Jenna
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way.
