Global Positioning System Abstract- Global Positioning System (GPS) is the only system today able to show ones own position on the earth any time in any weather‚ anywhere. This paper addresses this satellite based navigation system at length. The different segments of GPS viz. space segment‚ control segment‚ user segment are discussed. In addition‚ how this amazing system GPS works‚ is clearly described. The various errors that degrade the performance of GPS are also

------------------------------------------------- Global warming Global warming is the rise in the average temperature of Earth’s atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century‚ Earth’s mean surface temperature has increased by about 0.8 °C (1.4 °F)‚ with about two-thirds of the increase occurring since 1980.[2] Warming of the climate system is unequivocal‚ and scientists are more than 90% certain that it is primarily caused by increasing

Global Warming And Its Effects On The Coastal Areas of Bangladesh [pic] [pic][pic] GLOBAL WARMING: Global Warming is the rise in the average temperature of the Earth’s atmosphere‚ including the surface air and oceans. In simple words global warming is when the Earth heats up. It is caused mainly due to increasing concentration of greenhouse gases in the Earth’s atmosphere. The greenhouse gases‚ include carbon dioxide‚ nitrous oxide‚ methane‚ water vapor‚ traps heat and light in the

DO VOLCANOES HAVE A DESTRUCTIVE POWER AS WELL AS POTENTIAL BENEFIT Volcanoes are usually depicted as towering mountains missing a chunk out of the top from which steam‚ ash and lava spew forth. In reality‚ a volcano is any spot on the surface of the Earth where lava flows. Magma finds its way upwards along fissures or cracks in the planet ’s crust and bursts out onto the surface‚ resulting in a volcano. Magma that flows out of a volcano is called lava. If it comes out of the volcano in an explosive

Global Warming: We Are All Guilty For every person with an opinion‚ there is another person who believes the opposite. This goes for almost any public affair in today’s society‚ it is a part of human nature to disagree and argue. Considering this‚ it is no surprise that there are many differing opinions on the numerous different parts of one of today’s biggest issues: global warming. In most cases it is perfectly fine to have differing opinions on issues. However‚ this is becoming too big of

CHAPTER 7 SPEED - Is a scalar -measures “how fast an object is moving” INSTANTANEOUS SPEED -the speed at any given instant in time AVERAGE SPEED -the average of all instantaneous speed; found simply by a distance or time ratio. SPEED= distance/Time TIME= Distance/Time DISTAnce= Speed*Time VELOCITY- is a vector Refers to the rate at which an object changes its position VELOCITY= displacement/time MOTION- is a change in position with respect to a reference ENERGY-
