Biot-Savart Law A law which describes the contributions to a magnetic field by an electric current. It is analogous toCoulomb’s law. Centrifugal Pseudoforce A pseudoforce on an object when it is moving in uniform circular motion. The "force" is directed outward from the center of motion. Charles’ Law (1787) The volume

1973-1974 Oil Embargo The oil embargo of 1973 was one of the most significant events regarding the United States macroeconomy. This event was a refusal of Arab countries to sell oil to pro-Israeli countries. The embargo began on October 17‚ 1973‚ when the Organization of Arab Petroleum Exporting Countries‚ or OAPEC‚ declared they would immediately cut oil production by 5 percent and will continue until Israel withdrew from the West Bank‚ Gaza‚ and Jerusalem. Saudi Arabia and Kuwait soon followed

magnetic field perpendicular to the deflecting electric field is produced using a pair of bar magnets. The position of the magnets is adjusted so as to cancel the deflection of the electrons. The knowledge of the deflecting potential and the magnet field of the bar magnets leads to a calculation of the specific charge. I. Introduction We have learnt that the electron has a negative charge whose magnitude e equals 1.6 × 10−19 Coulomb and mass (m) equal to 9.1 × 10 −31 Kg. Millikan’s Oil Drop method

Soldier Field I have never been astounded by such marvelous architecture until I laid my eyes on Soldier Field in Chicago‚ Illinois. Soldier Field seemed like a dragon‚ just engulfing everyone who was spectating the Mexico vs Bosnia game on May 2011. When I first laid eyes on the monstrosity‚ I was very intimidated. The thought of entering this behemoth marveled me and made me even more excited to enter and watch the Mexico soccer game that I was anxiously waiting for! Chicago itself is a marvelous

In Flanders Field Cold Commentary In Flanders’s Field is a war poem filled with emotions that probably relate to World War One. The strange thing this poem does not have a sort of morning/sad tone to it which was typical after the world experienced the horrors of World War One. This poem has a very strong feeling of fighting on and “hold [the torch] high”(12) feeling. This is due to a lot of different reasons. The most prominent is the fact that this poem seems to be from a single entity

Since 1995‚ Indian share in world production of oilseeds has been around 10 percent. Although‚ India is a major producer of oilseeds‚ per capita oil consumption in India is only 10.6 kg/annum which is low compared to 12.5 kg/annum in China‚ 20.8 kg/annum
