The solar energy use in Africa These days‚ solar energy has been the most talkative alternative energy source in the world. Unlike the gas‚ oil‚ and coal‚ solar enrgy is one of the clean and renewable resource‚ which can not only generate power but also protect the environment. Africa‚ has second largest population‚ estimated 1.6 billion‚ however‚ around one third of it’s people still live in the condition with no eletricity. (Renewable energy in Africa

The Action of Tiger Conservation As the population of tiger in the world dwindles nowadays‚ everyone has the responsibility for the conservation of tiger especially tiger range countries. Over the past 100 years‚ tiger numbers have declined by 95 percent which leave only 3‚200 and three sub-species have become extinct – with a fourth not seen in the wild for over 25 years (World Wild Fund for Nature [WWF] International‚ 2008). Since it is estimated that wild tiger number halved to 3‚200‚ we

If it weren ’t for us‚ the tigers would not go extinct much less be endangered. We don ’t eat tigers so why are they so endangered? Information "Of the eight original species of tigers‚ three have become extinct in the last 60 years‚ an average of one every 20

1.Introduction: Wildlife conservation is the practice of protecting wild plant and animal species and their habitats. Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife and wilderness lands to humans. Many nations have government agencies dedicated to wildlife conservation‚ which help to implement policies designed to protect wildlife. Numerous independent non-profit organizations also promote

Wildlife conservation encompasses all human activities and efforts directed to preserve wild animals from extinction. It involves both protection and scientific management of wild species and their environment. Some species have become extinct due to natural causes‚ but the greatest danger to wildlife results from the activities of man. So we ourselves have created the need for conservation of wildlife. It can be viewed from several angles such as‚ beauty‚‚ economic value‚ scientific values for

experiment is to study the principle of conservation of momentum in collisions using two bodies. We also calculated the amount of kinetic energy in elastic and inelastic collisions before and after the collision. Introduction: When bodies collide with each other‚ the total momentum p = mv‚ is always conserved regardless of the type of collision provided no external forces are present. There are two types of collisions. In an elastic collision‚ both the kinetic energy and the momentum are conserved. An

Water conservation importance. Water is very important content. With out water there is no life in earth. We use water in so many ways in our daily life. Water is a substance which covers ¾ part of the world. It means water is occupying more portion compared to land. But this water is becoming more polluted because of the environmental changes. So it is necessary to conserve the water. It is every one duty to protect the water because everyone uses this water and we the people are making water polluted

Scientific laws explain observations and experiments that are verified and considered very high forms of scientific intelligence. The law of conservation of mass states that mass in an isolated system cannot be created or destroyed in an ordinary chemical reaction; rather conserved. In an easier explanation‚ everything you start with‚ you must end with. Although‚ the substance can look or be shaped differently from the original. Mass is a measure of the amount of matter an object contains. An example

ENERGY MANAGEMENT PRINCIPLES INTRODUCTION In the modern days energy has the significant role in our life. With development where we got comfortable life and much modern facilities where we got some problem with excessive use of energy resources as declining of energy sources‚ climate change. So it is an big challenge for present and future generations as the cost of energy increase and its supply decrease‚ older buildings needs to modified and new buildings designed to use less energy. The optimization

Law of Conservation of Mass Lab Introduction- Problem: To validate the law of conservation of mass and to examine what happens when one Alka- Seltzer tablet is combined with water. Hypothesis: If the Alka-Seltzer tablet is combined with water‚ then Co2 will be produced because when mixing the two compounds‚ a chemical reaction will occur.
