fluid‚ the sum of the static pressure‚ the weight of the fluid per unit mass times the height‚ and half the density times the velocity squared is constant throughout the fluid. 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

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

Paddy Field Fish Culture (also named Fish Culture in Paddy Field) Problem Identification: The bad harvest of paddy resulting in a high price of rice‚ accompanying with the low income of farmers. Problem Delineation: Firstly‚ the growth of paddy needs a mass of water to survive‚ and it is hard and cost to fertilizer and to sterilize the fields‚ especially in a rainy season. And manure is hardly to be absorbed sometimes. In addition‚ there are usually some problems with pests and weeds‚ which

Electric Fields Lab Abstract: In this lab we will study the equipotential lines in an electric field in order to study the structure of the electric lines of force. We will plot the position of electric field lines in a given electric field using both a manual method and a computer software program. There is an electric field in any region where there is a force on an electric charge at rest. It is convenient to represent an electric field by the

CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT. A 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
