Why is magnetic flux through closed surface zero while electric flux not? Gauss’ Law for Magnetism The net magnetic flux out of any closed surface is zero. This amounts to a statement about the sources of magnetic field. For a magnetic dipole‚ any closed surface the magnetic flux directed inward toward the south pole will equal the flux outward from the north pole. The net flux will always be zero for dipole sources. If there were a magnetic monopole source‚ this would give a non-zero area integral

Comparison of One Art and Because I liked you Better In the poems “One Art” and “Because I Liked You Better” ‚ both poets Elizabeth Bishop and A.E. Housman express a strong sense of rejected love and great emotion. The poems share many commonalities in the sense that both of them deal with poets attempting to convince themselves that what they are feeling can be put away emotionally‚ but after both shifts‚ it becomes obvious that the strong emotions which both Houseman and Bishop are feeling cannot

Title: Thin-Layer Chromatography Objectives: Part1: 1. To learn the technique of TLC and the visualization of colourless components. 2. To identify an unknown drug by a TLC comparison with standard compounds. Part 2: To learn the separation technique by using Thin Layer Chromatography plate in separating a mixture of compounds into individual pure compound by using Spinach Leaf. Introduction: (i) General Concepts Chromatography is a common and powerful method used to separate and analyze complex

Does classical music really help you study better? Many recent research studies show that music indeed does in fact improve thinking. In 1993‚ researchers at the University of California at Irvine discovered the so-called Mozart Effect - that college students “who listened to ten minutes of Mozart’s Sonata for Two Pianos in D major K448 before taking an IQ test scored nine points higher” than when they had sat in silence or listened to relaxation tapes. Other studies have also indicated that it doesn’t

Part three Explaining how a thicker wing can be lighter than a thin wing when both are built for the same purpose: Firstly‚ the principle applying to the mass and thickness of wings applies to any aerofoil surface in any shape or form. How do we know a delta wing and a swept wing have heavier masses than a straight wing? Two important things need to come into account when measuring the thickness and weighing certain types of wings‚ the structural ‘Aspect Ratio’ and the ‘Thickness Ratio’ of aerofoil

Source of Electricity in South Sulawesi In South Sulawesi the 2 basic methods of producing Electric Power are hydroelectric generation‚ based on the energy contained in flowing water‚ and thermal generation‚ based on the production of steam. At the centre of nearly all power stations is a generator‚ a rotating machine that converts mechanical energy into electrical energy by creating relative motion between a magnetic field and a conductor. The energy source harnessed to turn the generator varies

hence forms one or more new substances is called a chemical change‚ or more often‚ a chemical reaction (James T. Shipman 342).” In this summary paper‚ I will discuss some of the highlights of the chapter. An awesome example of a chemical reaction is that of photosynthesis‚ found in green plants. In photosynthesis‚ plants absorb carbon dioxide gas from the air‚ with energy from the sun‚ water from the soil and chlorophyll to make carbohydrates for food.

Mary Emeny’s poem‚ "Barbed Wire‚" depicts war as a negative force‚ destroying every decent aspect of human existence. Written during the Vietnam War‚ the work displays Emeny’s negative views on war. In one way or another everyone experiences and identifies with the presence of war. Although some wars are fought for justifiable reasons‚ every war tears into the lives of those undeserving. The tragic effects of war consume the innocent creating an unconquerable path of entanglement. The physical

Thin Layer Chromatography Introduction Thin Layer Chromatography or TLC is a technique used as a separation and identification technique. There are many forms of chromatography‚ but one thing that remains constant throughout all of the types of chromatography is that there is a stationary phase and a mobile phase. In the case of TLC the stationary phase is the silica gel on the TLC tray. Procedure Chromatograph method is a method of separating mixtures of two or more compounds. Two phases
