ExpertsMind > Physics Help >> Magnetism - Magnetic Field of Earth Sir William Gilbert was the first to suggest in the year 1600 that earth itself is a huge magnet. His statement was based on the following evidence: (i) A magnet suspended from a thread and free to rotate in a horizontal plane comes to rest along ht north-south direction. On disturbing the magnet returns quickly to its north-south direction aging. This is as if a huge bar magnet is placed approximately along the axis of rotation of earth and deep in its interior. The north pole of this fictitious magnet must be towards geographic south so as to attract worth plot of the suspended magnet and vice-versa. We must add here that fictitious explain the earth’s magnetic field and its peculiarities. In reality there is no such her magnet in the interior of the earth.  (ii) When a soft iron piece is buried under the surface of earth in the north south direction, it is found to acquire the properties of a magnet...

Macroeconomics Notes, Economics Theory for Fiscal Measures A three sector or a closed economy model is constructing by adding government sector to the two sector or simple economy model. The government influences the level of economic activities in a variety of ways through its economic activities, fiscal policy (government expenditure and taxation policies), monetary and credit policy, growth policy, industrial policy, labour policy, wage policy, employment policy, control and regulation of monopolies, export and import policies, environment policy etc. however, the closed model of the Keynesian income determination theory confines to the effects government expenditure (including transfer payments) and taxation. Thus, inclusion of the government sector into the simple economy model introduces three new variables to the model, viz, taxes (T), government expenditure (G) and transfer payments (GT). The inclusion of the government complicates the analysis by bringing in the complex syste...

ExpertsMind.com offers Microeconomics Theory and Concepts, & Economics Help What is Lemons Market? The important example of market with asymmetric information is the market for lemons. In the market for lemons the buyer’s as sellers have different information about the quality of the goods being bought and sold. The words lemon is used to describe a defective or low quality product let us consider the market for used cars. We assume that the used cars are of different qualities some of them are of good quality while other is just lemons. The bad quality car (lemons) quite often breaks down and requires lot of reprise. However while the sellers of used cars fully know the quality of their used cars, the buyers are uncertain about their quality due to lack of information. Therefore the market for used cars is an important example of asymmetric information. It is important to note that though some of he used cars available for sale are of bad quality, but all sellers who used cars ...

ExpertsMind.com >> Physics Assignment Help >>  Electromagnetism According to ampere’s circuital law the magnetic field b is elated to a net current I as B . dI = μiI Where I is the net currant threading the surface bounded by a closed path C. Maxwell in 1864 argued that the relation is logically inconsistent. He explained the same with the help of following observations. Consider a parallel plate capacitor having plates P and Q connected to a battery B through a tapping key k. when key k is pressed the conduction current flows through the connecting wires. The capacitor starts storing changes. As the charge on the capacitor grows the conduction current in the wires decreases. When the conduction current in the wires decreases. When the capacitor is fully charged the conducting current stops flowing in the wires. During charging of capacitor there is no conduction current between the plates of capacitor during charging let at an instant I be the conduction current ...

Hydrodynamics | Physics Assignment Help | ExpertsMind.com Fluid is something that can flow therefore liquids and gases come in this category. A perfect liquid cannot be compressed and shearing stress cannot be maintained. Streamlined steady state flow by steady state or stationary flow we mean that at any place in a fluid the velocity never changes. Streamline is a curve tangent to which at any point gives the direction of fluid velocity at that point. Equation of continuity volume entering per second = volume leaving per second Or A1 v1 = A2 v2 Where A and A2 are area of cross-sections and v1 and v2 are velocities at the two ends/points of a pipe. Bernoulli’s theorem it states that the total energy is constant. KE + PE + pressure head Energy = constant 1/2 mv2 + mgh + P∆V = constant Or 1/2 pv2 + pgh + P = constant In a horizontal pipe 1/2 pv2 + P = constant Torricelli’s theorem according to this theorem velocity of efflux v efflux = √2g (H- h) Velocity of ef...

Defining Paramagnetism | Chemistry Assignment Help , ExpertsMind.com Some normally nonmagnetic substances are attracted by a magnetic field and studies of these “paramagnetic” substances give information about the number of unpaired electrons in the atoms, molecules, or ions of the substance. The paramagnetic effect can be introduced problem of the magnetic behavior of an electron revolving about a nucleus. A classical treatment is easily made and yields a result which can then be converted to the correct quantum mechanical result. The motion of an electron in an orbit corresponds, in this connection, to the passage of a current through a coil of wire. A current in a coil of wire of ordinary dimensions produces a coil of wire. A current in a coil of wire of ordinary dimensions produces a magnetic field perpendicular to the coil. The magnetic field so produced is equal, according to Ampere’s law, to that of a magnet with magnetic moment given by the product of the current and the cro...

Capital Market Efficiency | Finance Assignment Help  | ExpertsMind.com The finance theory refers to three forms of capital market efficiency: • Weak-form of efficiency • Semi-strong form of efficiency • Strong-form of efficiency. Weak form of market efficiency The security prices reflect all past information about the price movements in the weak form of efficiency. Hence the weal form of efficiency is referred to as the random walk hypothesis. An alternative method of testing the weakly efficient market hypothesis is to formulate the trading strategies using the security prices and compare their performance with the stock market performance. The capital market will be inefficient if the investor’s trading strategy could beat the market. Researchers have studied a large number of trading rules, and have concluded that it is not possible for investors to outperform the market. Semi-strong form of market efficiency In the semi-strong form of efficiency, the security p...

Competitor Analysis The next level of analysis that a company needs to conduct is a detailed competitor analysis to understand competitors, their goals, strengths and weaknesses and reaction patterns. Firstly, an understanding of the current strengths and weaknesses of competitors can reveal threats and opportunities that merit action from a company. Secondly, it leads to an understanding of the goals and reaction patterns of competitors firms, which directly determine the outcome of a company’s strategic moves. No business strategy is by itself either a success or failure. It is the reaction and retaliation or the absence of a reaction which determines the outcome of a firm’s business strategy. Competitor analysis can be conducted using the following framework: 1. Size, growth and profitability The size of and company and growth of sales and market share provides indicators of the health of the business. The maintenance of a strong market position or the achievement of rapid...

Stabilization Energy We have learnt that in octahedral field, the energies of five d-orbital split-up. Three orbitals are lowered in energy  (t 2 g)  and two orbitals are raised in energy (eg). We know that electrons always prefer to occupy an orbital of lower energy. For example, in the case of d1 system (e.g.  Ti 3+   in  [TiF 6 ] 3- ), the d-electron will prefer to occupy a  t 2 g orbital and is, therefore, stabilized by an amount equal to 0.4  Δ 0  or 4 Dq. The amount of stabilization provided by splitting of the d-orbitals into two levels is called crystal field stabilization energy. It is abbreviated as CFSE. Thus, in octahedral field for each electron entering into the  t 2 g  orbital, the crystal field stabilization is -4 Dq and for each electron entering into the eg orbital the crystal field destabilizing energy is  +6 Dq . Thus, the CFSE is calculated as the algebraic sum of -4 Dq per electron in  t 2 g  level ...
