This question deals with ideal, linear polarizers: a. With unpolarized light incident on a linear polarizer, you measure a power of 2 mW after the polarizer. A second polarizer is then inserted into the system, and you then measure 0.5 mW. What is the angle between the pass axes of the two polarizers? b. With 5 mW of light of an unknown polarization incident on a linear polarizer, you measure no light after the polarizer. If you put another linear polarizer before the one used above with its pass axis oriented 60? with respect to the other, how much power should you measure? c. Repeat (b) but now putting the additional polarizer after the first rather than before it. Solution here, a) the initial intensity of polarizer , I0 = 2 mW the final intensity , I = 0.5 mW let the angle between the polarizers be theta I = I * ( cos(theta))^2 0.5 = 2 * ( cos(theta))^2 solving for theta theta = 60 degree the angle between the pass axes of the polarizers is 60 degree .

This International Business conversation focuses on government intervention and regional integration: 1. What are the pros and cons? Make two lists, pros on one side and cons on the other. 2. Why is there no such thing as unimpeded free trade? That is, what is the justification for government intervention? 3. By contrast, why is free trade good? 4. In its efforts at political and economic unification, the EU struggles with national sovereignty issues and with division rather than collaboration. The quest for a constitution that clarifies the distribution of powers and legitimizes the EU Solution 1) Pros and cons A number of Wikipedia articles today contain pro & con lists : lists of arguments for and against some particular contention or position. These take several forms, including lists of advantages & disadvantages of a technology or proposal (such as Wi-Fi) and lists of criticisms & defenses of a political position or other view (such as socialism or creationism; lists on those articles have since been removed). Structure of a pro & con list Pro & con lists fragment the presentation of facts . There are many issues on which there is a difference of opinion over whether some fact is a benefit or a detriment. For instance, it is a fact that Wi-Fi networks use unlicensed radio spectrum. This has advantages and disadvantages, many of which are subjective or relative. However, in a pro & con list, the advantages of unlicensed spectrum will be grouped with other unrelated advantages, and the disadvantages with unrelated disadvantages .

Thin film transistors (TFTs) are used in direct digital radiography systems to: a)Â Â Â Â Â Â Â Â Â Â Â Â Â Produce a flash of light b)Â Â Â Â Â Â Â Â Â Â Â Â Convert the X-ray energy to an electrical charge c)Â Â Â Â Â Â Â Â Â Â Â Â Â Temporarily store the electric charge d)Â Â Â Â Â Â Â Â Â Â Â Â Trap the electrons in the photostimulable phosphor e)Â Â Â Â Â Â Â Â Â Â Â Â Â Bind the photostimulable phosphor to the glass screen Solution answer is (b) Convert the X-ray energy to an electrical charge. Direct-conversion detectors have an X-ray photoconductor, such as amorphous selenium, that directly converts X- ray photons into an electric charge. The selenium-based technology uses an amorphous selenium-coated thin-film-transistor (TFT) array to capture and convert X-ray energy directly into digital signals. It is a direct-conversion technology that converts X-ray beams into electric charges directly. .

There are several arsenic minerals, two of which are claudetite (As2O3) and orpiment (As2S3). Wrtie a balanced half cell reaction between these two minerals, in an aqueous solution. The half cell reaction is: As2O3 + 3 SO4^2- + 30H+ +24e- <--> As2S3 + 15H2O How do you know that As2O3 will be on the left side of the equation than the right? How do you know to add SO4^2- to the equation? How do you know to add the 24e- to the left side of the equation? If someone could show me steps to explain these questions, it\'d help me out a lot. Thank you. Solution The half cell reaction is: As 2 O 3 + 3 SO 4 2- + 30H + +24e - <--> As 2 S 3 + 15H 2 O How do you know that As 2 O 3 will be on the left side of the equation than the right? Ans:- As 2 O 3 is soluble in dilute acids and this reaction takes place in acidic condition that is why As 2 O 3 is on left hand side. As 2 S 3 is not soluble in acid at room temperature that is why this will be on right hand side of the equation. How do you know to add SO 4 2- to the equation? Ans:- As this reaction takes place in acidic medium ,in the presence of sulphuric acid (H 2 SO 4 ) that is why ionised form of sulphuric acid i.e.SO 4 2- is added to the solution. How do you know to add the 24e- to the left side of the equation? Ans:- To balance the charge of the half cell reaction.There is no charge on the right hand side and a (24H + ) + 3(-2) = (30+) - 6 = 24+ charge on the left side of the equation.so to balance this charge add 24 e - to the equation.Now equation become neutral. .

There are a variety of forecasting techniques that a company may use. Identify and discuss the four main qualitative approaches, including their advantages and disadvantages. Solution Qualitative forecasting techniques generally employ the judgment of experts in the appropriate field to generate forecasts. A key advantage of these procedures is that they can be applied in situations where historical data are simply not available. Moreover, even when historical data are available, significant changes in environmental conditions affecting the relevant time series may make the use of past data irrelevant and questionable in forecasting future values of the time series. DELPHI TECHNIQUE. In the Delphi technique, an attempt is made to develop forecasts through \"group consensus.\" Usually, a panel of experts is asked to respond to a series of questionnaires. The experts, physically separated from and unknown to each other, are asked to respond to an initial questionnaire (a set of questions). Then, a second questionnaire is prepared incorporating information and opinions of the whole group. Each expert is asked to reconsider and to revise his or her initial response to the questions. This process is continued until some degree of consensus among experts is reached. It should be noted that the objective of the Delphi technique is not to produce a single answer at the end. Instead, it attempts to produce a relatively narrow spread of opinions .

The VP of Human Resource was recently hired from Sloan Valve Company where they experienced challenges implementing IT driven change. He would like your team to provide the latest thinking on best practice in changing management startegies. Group presentation, please help!! Please be specific but make sure a normal person can understand. Solution There is always reluctance and resistance to change , even when the change is for the better. Fear of unknown , losing control , ego , fear of losing jobs etc are some of the reasons for which people resist change. Some of the ways in which implementation of IT driven change can be implemented are as follows: 1.Call key staffs and brief them about the plan of change and tell them what are the benefits.Assure them that no one is going to lose a job if this change is implemented. 2.Let these key staffs act as advocates for the company and they in turn should convey the message to all their subordinates. 3.Make a commitee consisting os staffs from different levels and assign them the responsibility of implementing the change. 4.Hold regular meeting with this team to check the progress of the implementation and bottlencks if any. 5.Acknowledge their contribution and reward them after the change is completely implemented and adopted. 6.Let the same team monitor the institutionalization of the change, that is the change should be permanent. .

The world has gone through several different international financial orders over past 100 years. Explain how each one came into being and why the order eventually ran into difficulties and was suspended by another order. Solution It is valid to express that in the course of the last 100 years,there have been various activities taken by distinctive worldwide monetary offices to fortify the world economies and encourage financial exchange between them. Foundation of national banks, contriving trade rates, dissemination of capital streams into different economies, setting up of world bank & global financial store thus on could be reviewed in such manner. All these steps were gone for incorporating the economies of the world to advance development and social prosperity. However, it is the interest supply circumstance winning inside different economies of the world which really brought on a few basic circumstances because of which the world on different event went under the grasp of sorrow and subsidence. The colossal despondency of 1930s and in addition retreat post 2008 could serve as two essential occasions which stunned the whole world and brought about a reevaluate over the monetary requests which were predominant amid those time-periods. Presently comes the inquiry concerning why they ran into troubles. The significant explanation for every one of those happenings has constantly been absence of interest. Amid these periods in particulars, there had been sharp decrease popular coming about because of less liquidity in the economy because of not sufficiently having obtaining power.And the significant purpose behind these occurance had been liberal credit strategy of the budgetary framework .
