increases the temperature. This hurts many people‚ animals‚ and plants. The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day‚ the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car‚ by going through the windows‚ but it can’t get back out. This is what the greenhouse effect does to the

Global warming is the observed increase in the average temperature of the Earth ’s near-surface air and oceans in recent decades and its projected continuation. Global warming poses an extraordinary challenge. The world ’s leading atmospheric scientists tell us that a gradual warming of our climate is underway and will continue. This long-term warming trend poses serious risks to our economy and our environment. It poses even greater risks to many other nations‚ particularly poorer countries that

conductors will balance this magnetic influence‚ producing a measurable voltage between the two sides of the conductor. This presence of measurable transverse voltage is the Hall Effect. The Hall effect was discovered in 1879 by Edwin Herbert Hall while working on his doctoral degree at the Johns Hopkins University. The Hall effect is due to the nature of current in a conductor. Current consists of the movement of many small carriers(electrons‚ holes or both). Moving charges experience the Lorentz force

Executive Summary The recent acquisition of French energy company Alstom by General Electric has made a lot of headlines in the world recently. This is one of the largest acquisitions by the General Electric and involved a lot of complexities. The Alstom’s board of directors was ready to cut the deal with General Electric but French government has made this deal as the national pride and tried to interfere. They opposed this deal on the ground of loss of jobs in France but in reality the French

Greenhouse Effect When one starts a car or burns wood‚ the last thought on their mind is the consequences to these actions. Unfortunately‚ the daily dangers to earth are not widely know. Due to the constant change of society‚ this planet must cope with various problems. One of the most important ecological structures is the ozone layer. The same shield that protects us from the sun ’s deadly radiation‚ can also act as a blanket engulfing us in heat. This situation is know as the greenhouse effect. What

Doppler effect The Doppler effect‚ named after Christian Doppler‚ is the change in frequency and wavelength of a wave as perceived by an observer moving relative to the source of the waves. For waves that propagate in a wave medium‚ such as sound waves‚ the velocity of the observer and of the source are relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from motion of the source‚ motion of the observer‚ or motion of the medium. Each of these

we hear and are caused by vibrations that travel through mediums. Depending on the medium and temperature‚ the time it takes for sound waves to travel vary. The hypothesis states that if the temperature in the air increases‚ then the speed of sound will also increase because faster-moving particles transfer energy quickly. The data collected supports the hypothesis. Therefore‚ increased air temperature affects the speed of sound because the molecules move faster‚ which causes the energy to be transferred
