The correct graph to illustrate the relationship between the carrier gas flow rate and the height of theoretical plates in a gas chromatographic separation is 21. Experimentally, the plot of absorbance (A) vs concentration (C) should be 3 of 4 Solution 20 ) C is the answer VANDEEMTER PLOT ( releates flow rate or linear velocity to H ) H = A + B/mew +C/mew, one use of plate height is to releate this kinetic process band broadening to a prameter of the chromatographic system ( eg: flow rate ) 21 ) A is the answer The linear relationship between concentration and absorbance is both simple and straightforward, which is why we prefer to express the Beer-Lambert law using absorbance as a measure of the absorption rather than %T. the Law is not obeyed at high concentrations. This is deviation from the Law .

International business is conducted outside of the home country. Nations represent cultural diversity, with unique values, metaphors, stereotypes, idioms and language. How will you deal with people from another country? How will you function effectively when visiting countries with distinctive cultures, such as Mexico, China, Russia, Japan, or Switzerland? Solution There is no culture-free theory of management. Managing other people is the responsibility of people who, like everyone else, have been enculturated and socialized into a cultural set of values and beliefs that governs their thinking, emotions, and behaviors. Like communication, management is culture bound. Moreover, managerial perceptions regarding the factors that lead to organizational success vary across cultures. Unfortunately, many U.S. managers are ill equipped to handle overseas assignments. In fact, roughly 40% to 50% of all U.S. managers sent abroad receive no formal cross-cultural training. As a result, up to 40% of overseas assignments are unsuccessful. Although fostering competent intercultural managerial skills represents an enormous challenge, the rewards of successful international commerce are extraordinary. Professor Philip Rosenzweig of Harvard University argues that successful cross-cultural management depends on the abilities of managers to communicate effectively. Rosenzweig points out that communication is especially important during the initial stages of a business relationship. Depending on the culture, the process of building trust among business partners may take days, weeks, or even months. Moreover, Rosenzweig asserts, this process cannot be accelerated. Rosenzweig recognizes that many American managers prefer to .

Insight Communications Promotes employees with good technical skills into supervisory positions and then teaches them leadership skills.Is this the vst way for the company to get supervisors to lead well?Why and why not Solution This is the best way for the company to get supervisors to lead well. 1) This is because the already skilled employees of the comapany are turned into supervisors. 2) They have a know-how of how work is done in the company. 3) They have better rapport(communications ) with other employess. If instead of this a supervisor is hired as a completly new employee, he will then only have the leadership and management skills. He won\'t have technical skills like an internal employee of the company. This is a major demerit because a person is supervising othe employees who dosen\'t know about the technical work the employees are doing. How can he supervise them? 4) They have a technical know-how. 5) the will cost the company less to convert alredy existing staff to supervisor tha to hire a new one .

Infrared radiation is also called IR. Describe how it is different from visible light. What emits IR? Can animals use it? Explain how emission of IR sometimes â€œwastesâ€ energy. Give examples showing how IR is used in modern technology. Solution Infrared Radiation consists of electromagnetic waves with wavelengths ranging from 700 nm to 1 mm. These radiations cannot be detected by human eye. On the other hand, visible light consists of electromagnetic waves ranging from 380 nm to 700 nm. These radiations can be detected by human eye. IR are also known as thermal radiations. All objects emit and absorb IR. The hotter the object, the more IR it will emit. Dark surfaces are good emitters of IR. Some animals have the ability to sense IR, known as IR vision. These animals have specialised IR sensing organs known as pit organs. For example: snake, mosquitoes, bed bugs and vampire bats are kind of animals that uses IR sensing to track their prey or any potential danger approaching them. Infrared radiations are associated with thermal energy. In most of the devices, emission of thermal energy is waste of energy. For example: a light bulb generates heat along with light energy on passage of electricity. Now this heat energy is not a useful energy and gets wasted in the environment. Use of IR in Modern technology: 1. It is used in heat sensitive thermal imaging cameras. They are used to study heat patterns of humans and animals. They are also used as night cameras. 2. IR is used in gas monitoring and analyzing systems. These systems are used for testing air samples to see what gases are contained in that sample. 3. It is used in thermal imaging and thermal motion detection. Thermal imaging is used by firefighters to see where a burning building is too hot to safely enter. Thermal imaging is used for space imaging and to know the temperature of distant stars. .

Infrared radiation is also called IR. Describe how it is different from visible light. What emits IR? Can animals use it? Explain how emission of IR sometimes â€œwastesâ€ energy. Give examples showing how IR is used in modern technology. Solution basic differences are- The electromagnetic spectrum comprises all wavelengths of light from the very short (gamma rays) to the very long (radio waves). Both visible and IR light are near the middle of the spectrum The wavelength of an electromagnetic wave is the distance between peaks (or troughs) of the wave. IR radiation has longer wavelengths than visible light. The frequency of a wave is a measure of how many times the wave oscillates between its minimum and maximum amplitude in one second. The frequencies of IR waves are less than the frequencies of visible ligh All objects on Earth emit ir r adiation Blood-sucking insects, such as bedbugs and mosquitoes, rely on their infrared vision to feed themselves. They can \"see\" body heat and use the heat signature of the carbon dioxide (CO2) gas that humans and other animals naturally exhale to locate their prey. it waste enegy in form of greenhouse effect Far Infrared Light Can Be used For Anti-terror Devices, Faster Wireless. ...

In the given cell, Fe is acting as cathode. Hence it should undergo reduction. your equation representing reduction of Fe 2+ to Fe is right. ii) Ionic equation including state symbols is asked. Ionic equation is nothing but the overall cell reaction represented in ionic form. Simply it is combination of cathode half reaction and anode half reaction. In the given cell, Magnesium is the anode. It undergoes oxidation. i.e. Mg(s) to Mg 2+ by loss of two electrons. We have already seen the cathode half reaction of reduction of Fe.

Inorganic Chemistry - Wurtzite vs. Rock-Salt Structures Beryllium oxide (BeO) prefers the Wurtzite structure type (typical of ZnS) while LiF prefers the rock-salt structure type (typical of NaCI). Why does this happen? Use the following terms/words in your explanation a) ionic radii b) chemical bonding Solution Beryllium oxide prefers wurtzite structure type whereas LiF prefers rocksalt type structure. If we look all these elements, namely, Be, O, Li, and F falls in the second period of periodic structure. Atomic radius decreases from left to right in the periodic table. This is because of addition of an electron in the same shell of the atom which compresses the atom due to more attraction towarrds the nucleus. The electronegativity of elements increases from left to right since it is inverse property of atomic radii. Atomic radius of Be 2+ is less than Li + whereas atomic size of O 2- is more than F - . Moreover, LiF is ionic in natute due to coulombic interaction of highly electropositive atom (Li) and highly electronegative atom (F). On the other hand, BeO is having covalent character along with ionic character in their chemical bond. Thus, BeO prefers wurtzite structure type whereas LiF prefers rocksalt type structure. .

Indonesian lenders are the most profitable business in the world. The average return on equity is 23% more than double the 9% in the US. The main issue is he limited supply of official lenders, prompting an average interest of 16-20% for short term loans (BusinessWeek, 2/24/13). Some consider this a form of usury. Usury is an excessive or exorbitant interest charge. In order to prevent usury, and politicians trying to save the \"little guy\" from the clutches of the greedy \"money lenders\", Indonesian government steps in and sets the upper limits on what can be charged for loan to 18%. Today, market forces pushed the interest rate at 20%, only $10 million in loans were made but 32 million were demanded. Graph the loan market and show the impact of setting upper limits on interest rate. Please explain. Solution it happend because of the government intervention, according to this expanation it is obeserving that the Indonesian business entities are in need of funds and even there are some people, having with surplus funds. becuse of the ceiling in interest the flow of funds declined into the market, if the situation runs for a long while it leads to create many problems. the supply is lesser than demand of funds, so automatically the lenders seek high interest rates other wise they wont ready to lend their money at lesser interest rates. .

In view of the Rutherford model of the atom, is the relative penetrating power of natural radioactivity to be expected? Explain. Solution Solution: In Rutherford\'s nuclear model of atom entire positive charge and most of the mass are concentrated in the centre. This central part is termed as nucleus. Electrons carrying negative charge revolve around the nucleus in orbits. In view of the Rutherford model of the atom, when alpha particles coming out of a radioactive material bombard the metal foil, many of the alpha particles pass through the metal because most of the part in the target atom is empty. It is also observed that radioactive radiations can penetrate the atoms of different elements and the scattering rate can be low. The reverse is also true by suitable combinations of radioactive radiations and atoms of different elements. Therefore, we can say that the relative penetrating power of natural radioactivity is expected. The alpha particles which collide with the central dense part called nucleus suffer scattering and do not penetrate the nucleus. The atomic electrons being light do not affect the alpha particles. .

In what ways has learning about world religions influenced the way you think about religion? Solution I just think it\'s important to learn about as much as possible in order to broaden your mind, studying other religions hasn\'t really affected my beliefs though. I am a Catholic, but I am and always have been aware that there is a definite possibility that I could be wrong. Learning about the religioins of the world made me realize how arbitrary adherence to religion is. It is almost always an accident of birth. Hindus will raise children to be Hindus; Shintos will raise children to be Shintos; Christians will raise Christians; it\'s all learned behavior and passed on from generation to generation. There are exceptions. People turn to religion after hitting rock bottom with addiction, or they have hard emotional or economic times, or they just like what they hear when they talk to members of a certain sect. Knowing about world religions only reinforces my rejection of them. There are too many, and they are too divided, both from each other and from within, to buy into any of them. .
