Results and Discussion As there were five similar experiments done‚ there is one common observed behavior – similar charges repel and opposite charges attract. The experiment went expected as there were no unusual observations recorded. In the first part‚ it was observed that when the plastic rod was rubbed it attracted the tissue bits. The explanation with this is‚ when the plastic rod was rubbed‚ it became electrically charged. Conduction happens when the tissue paper was rubbed into the plastic

few years the WHO (World Health Organization) concerned about the public health‚ conducted the largest global systematic study to discover the causes of major health risk factors‚ the statistics about air pollution stood out the most due to the deaths caused by air pollution. Michael Graham Richard reports that 3.5 million deaths are caused by indoor air pollution and 3.3 million deaths are caused due to outdoor pollution. This essay will be discussing the use of electrostatic precipitator in reduction

Calculate the electric force between two point charges of 4.00 µC and 3.00 µC when they are 2.00 cm apart. 2. Two points of equal charge produce an electric force on each other of 3.40x10 -2 N when placed 0.100 m apart. What is the charge on each point? 3. How far apart are two point charges of 2.0x10-6 C and 4.0x10-6 C if they produce an electric force of 0.56

whole world‚ also known as a one-world government‚ seems like a very unconvincing idea. Though‚ as we advance into the future‚ signs of a one-world government are beginning to show. One sign that a one-world government may be coming is the forming of multi-national governments and international organizations. So how likely is it that a one-world government will occur? The possibility is highly likely that a one-world government will occur. A significant scheme involved with the one-world government

Some parts of the world connect closer than ever before range from law to currency‚ like the European Unions. Some people come up with such an idea that is what if we use the same currency all over the world? There is no doubt that using one-world currency will bring lots of benefits to international

World War 1 “The war to end all wars.” This was the common name used for World War 1 but truthfully I do not believe there will ever be a war that ends all wars forever. This war struck fear into the hearts of not only soldiers in the war but citizens caught in the cross fire of the hatred that was plaguing our world. This war started for many reasons such as nationalism‚ imperialism‚ militarism and the formations of alliances. But the main reason this war was fought was because of a countries

ONE WORLD ESSAY Naud Veldhoen Ikea sell an estimated 3 million inedible items in 41 countries everyday. Almost all of these items include wood‚ plastic and metal‚ which means that they all contribute to global warming1. This makes Ikea a major culprit when it comes to climate change. Yet‚ Ikea are taking the necessary steps to eradicate further climate change. Ikea aim to increase energy efficiency by twenty five percent by 2015‚ and by 2020 Ikea aim to make more energy than it uses. In addition

factors‚ she was definitely not the lone cause. Many powerful European nations played a roughly equal part in their contribution‚ which consequently started the First World War. At the beginning of the 20th Century there was great imperialistic rivalry in Europe. This rivalry can be referred to as the "root" of all the major causes of World War I. Imperialism led to strained relationships between the powers (Germany often clashed with Britain and France over the rule of African countries‚ and France

One World Essay Georgia Beggs 3AB/Biology October 8‚ 2012 Human beings cause a lot of damage to the environment. However‚ as countries become more prosperous‚ they typically take better care of the environment because they can afford to care about quality of life issues. The most controversial topic today about the environment is global warming which many scientists say is caused by increased economic activity through carbon dioxide emissions. Fortunately‚ the threat of global warming
