Why might a company accept a project or investment with an NPV less than zero? Solution A company accept a project or investment with an NPV less than zero due to many a points: 1. If a firm has poor corporate governance, managers may ignore the net present value rule. In order to appear active, management may take on negative NPV projects to give shareholders the illusion of ongoing corporate investment. 2. As the usefulness of net present value relies entirely upon accuracy of the expected income of a project and the discount rate. The company accepting a project of NPV less than zero on the assumption that the discount rate is set too high or expected income is too optimistic which has resulted in negative NPV. They accept the project on positive future. 3. If the Company is going with no business, then it might be tempted to accept a project with NPV less than zero. .

Why does the absorption spectrum of as semiconductor have a sharp/steep region in the middle and two flat regions on either side? For emission spectrum, why is the emission peak typically sharp (narrow)? Solution molecules absorb light to different excited states. Emission comes from the lowest of these states, called the S1 state. When a molecule is excited to a higher state it often ends up in this lowest excited state S1 and then emits radiation. In this case the excitation spectrum is the same as the absorption spectrum. However from a higher excited state a molecule does not have to go to the lowest excited state. It can directly go to the ground state for instance. Then it does not emit radiation. In this case the excitation spectrum only has the lowest energy absoption features. .

why is it important to understand cultures Solution It important to understand culture so then you can pass down traditions , know about your close friends, you, and your family tree. As well as to know how to respect and appreciate others at what they do . ..... There are many reasons why understanding different cultures is very important. A reason may be so that you can analyze things from a different point of view, outside you \"box\". Another reason is so that you can better understand why some people act the way they do and why they make certain decision because I think that the way someone gets brought up plays an important role in that. Some other reason is to respect other cultures and just enrich yourself with learning about new traditions etc.. .

Why is frequency reuse of 1 possible and what is the number of users per carrier it allows? Solution In a low loaded network, the scheduler in each cell has an easy life as the amount of UE(user equipment)\'s simultaneous active is little. But LTE(Long Term Evolution) can prove its superior Frequency Domain Scheduling algorithm\'s (which are eNB Vendor specific) when the network gets loaded and RSRQ gets below -12 dB ... - 16 dB due to high interCell Interference from neighbor cells when looking at a particular serving cell. The Scheduler on its own can schedule the UE\'s in its own cell according to his scheduling algorithm and/or takes InterCell Interference Co-ordination signaling via X2-interface into account and be restricted to schedule cdertain Resource Blocks so that cell edge users are less interfered. This of course can be considered as a soft-reuse which enforces an re-use > 1. No. of users >1 .

why EI can not be used in determining protein primary structures? Solution EI is considered a hard (high fragmentation) ionization method, since it uses high energetic electrons to produce ions. This leads to extensive fragmentation, which can be helpful for structure determination of unknown compounds. EI is the most useful for organic compounds which have a molecular weight below 600. EI is useful for mass range <1000 Da, But Fragmentation of proteins in the 13000 to 29000Da mass range observed. Therefore, EI can not be used in determining protein primary structures .

Why is anion suppression necessary in ion chromatography? Solution Anion suppression is mandatory in ion chromatography, particularly in anion exchange chromatography. In suppressed ion chromatography, the sample is introduced and flows along with an eluent to the ion exchange column where separation occurs. After the separation, the mixture of ions in the eluent is introduced to a suppressor which exchanges the eluent and counter ions with suppressor derived ions. This exchange of the eluent has two practical advantages: (i) The background conductivity of the eluent is reduced; this enhances the conductivity of the sample ions for easy detection by a conductivity detector. (ii) The baseline noise is reduced; this increases the signal to noise ratio and thus, the sensitivity of the instrument. .

why does an atoms electronegativity decrease down a column in the period table but increases across the row in the periodic table? Solution The electronegativity decreases down the group because the bonding pair is far away from the nucleus because of addition of extra shells. This also leads to the pure shieling because the second period element will only be shielded 1s2 electrons whereas higher period elements will be shielded by 1s2 2s2 2p6 electrons. Hence the electronegativity decreases down the group When we go from left to right in a period, the distance of presence of electrons remain the same, since we are in same shell but the charge on nucleus (increases due to increase in atomic number), the increase charge lead to attraction of electrons pair tightly making it more electronegative in nature .

Why does iodine have a much lower melting point than sodium iodide? Why does iodine have a much lower melting point than sodium iodide? Solution Iodine occurs in a solid form and it is comprised of molecular bonds. In case of NaI, it is comprised of corresponding ionic bonds. The lattice structure is formed in 1:1 ratio that means that for each Na + there exists I - Hence the interaction will be stronger and in order to melt the crystal structure of NaI, all the ionic bonds need to be broken which results in high energy consumption. Therefore, NaI has a higher melting point than Iodine. .

Why do soluble impurities lower Tf of a solvent? Will insoluble impurities lower Tf of a solvent? Solution T f stands for depression in freezing point. That is a decrease in the freezing point. A pure compound will have a unique freezing point at standard conditions. there will be some forces of attractions between the molecules of compound that held it together.(For example, crystalline solids will have well arreanged repearting unit cells and they are held together by some attraction forces. When some impurity is added to the crystalline solid, the arrangement of unit cells will be disturbed and hence the forces decreases. So, less energy will be sufficient to melt the solid). similarly, for any substance a large decrease inT f value is observed as the soluble impurity increases. whereas, when insoluble impurities are present, they interact with the componud very less and hence only a slight decrease is observed in T f value. .

Why does this kind of error happen? It is something about makefile, and it says I have two main function, why is it? Solution Error: For creation of executable c- files, main funciton is the entry of the program execution. If more than one main funciton causes this kind of error while creating a make file. Error correction: First make sure that no two main files are exist within the project . Then make sure which c-file contains main function that starts and use the remaining c-files. If countplus.c is main file that contains main function, then open sumnum.c and check if main function is exists . then remove the main function from sumnum.c and save it. If sumnum.c is main file that contains main function, then open countplus.c and check if main function is exists . then remove the main function from countplus.c and save it. and now create a make file. .

Why do high levels of accruals appear to be mispriced? Solution Richardson, Sloan, Soliman, and Tuna find empirical evidence that suggests that accruals are related to earnings persistence. In addition, the less reliable the accruals, the lower the earnings persistence. Furthermore, they find that the market does not fully price the less reliable accruals. Future stock returns appear to be negatively related to accruals, and the negative relation is stronger for less reliable accruals. Liu and Qi provide evidence that the potential mispricing of accruals is substantial. There are a number of possible reasons for the mispricing. Na .

why do assest accounts have a normal balance which is debit and liabilites and stockholders equity have a normal balance which is credit? Solution It is because of the three golden rules set by the accounting principles:- . 1)Debit what comes in , credit what goes out. . 2)Debit the receiver, credit the giver. . 3)Debit all expenses and losses, credit all incomes and gains. . When we purchase an asset it comes in our business- so we debit asset. So assets have a debit balance. . When we receive money from shareholders or loan from third party we credit them because we know -credit the giver.So. Liability and shareholder equity have a credit balance. .
