Why is it helpful to approach the marketing research process from a \"backward” approach? How can this backward approach lead to more useful research findings? Solution Backward approach in marketing design helps to analyse each stage properly and determines what comes after it. This will also give more control over realistic market picture rather than just historical data analysis. This gives more sensitive information from the end users and can work backward to integrate the necessary things more precisely.The backward approach will help the researchers to design the outcome more better so that they can define the problem statement more precisely. The backward approach avoids the usual glitches in research as it has more control over the end outcomes and can guide the researcher with more rational support. This will also reduce the overall time taken for data interpretation and give better control over classification of relevenat information and creating value added insights.Thys backward approach will help to guide the research forward and it is all about what it is required and what they need from the study so that routemap will be clear for all data collection sampling and processing..

Why was the iodide ion successful for the SN2 reactions? What if you had used NaF instead of
NaI? Could you use NaBr to react with alkyl chlorides? Could you use NaCl to react with alkyl
bromides?
Solution
Iodide ion is a good nucleophile because the electron on iodine is loosely bounded and I- is less
solvated and hence the size of I- is small in solution. Hence I- is good nucleophile.
Hence the iodide ion successful for the SN2 reactions.
Nucleophilicity order of halide ions
F- < Cl- < Br- < I-
Due to higher electronegativity of F and F- is highly solvated. so size of the solvated ion is large.
so F- is bad nucleophile. Hence SN2 reaction does not occur if we use NaF instead of NaI.
NaBr produce Br- ion which is beter nucleophile in compare to Cl-. so NaBr react with alkyl
chlorides by SN2 mechanism.
NaCl does not react with alkyl bromides because Cl- is bad nucleophile.

Explain why the vapor pressure of a solution made with a nonvolatile solution must be less than the vapor pressure of the pure solvent? Solution Escaping of solvent molecules from the surface of liquid to space is called vaporization. The vapors are then condensed. When there is an equilibrium between vaporization and condensation, the pressure exerted by the vapors of the liquid over the liquid is called vapor pressure. In a pure liquid, the entire surface is occupied by the molecules of the liquid whereas in the case of solution, the surface is occupied by the liquid molecuels and nonvolatile solute molecules. So, the number of solvent molecules escaping from the surface is reduced compare to the pure solvent, thus, the vapor pressure of solution is reduced. Hence, the vapor pressure of a solution of nonvolatile solution is less than the vapor pressure of the pure solvent..

What process causes plant ion-uptake to acidify soil? What soil pH range generally promotes the greatest availability of cations? Solution The process that causes plant ion-uptake to acidify soil is known as soil acidification. It is a process by which the soil pH decreases over time without producing any visible signs. Slow soil acidification occurs under natural conditions over thousands of years, with high rainfall areas most affected, whereas, rapid acidification occurs over a few years under intensive agricultural practices. Soil acidification affects the surface and the subsoil simultaneously. However, areas that remain unaffected by industrial pollution, there soil acidification is mainly caused by the release of protons (H+) during the oxidation of carbon (C), sulphur (S) and nitrogen (N) compounds in soils. During nitrogen cycling, the major processes leading to acidification consists of the cation imbalance over anion during uptake in the rhizosphere of plants, during nitrification from fixation or from the fertilizers, and during the removal of plant and animal products by leaching. The uptake of excess cations over anions by plants results in the acidification of the rhizosphere which is a “localized” effect and can be balanced by the release of hydroxyl (OH-) ions during subsequent plant decomposition. Soils are considered acidic below a pH of 5, and alkaline above a pH of 7.5 and very alkaline above a pH of 8. It has been observed that the “ideal” soil pH is close to neutral, which fall within a range from a slightly acidic pH of 6.5 to slightly alkaline pH of 7.5. It has been determined that most plant nutrients are optimally available to plants within this range helpful for plant root growth. However, Nitrogen (N), Potassium (K), and Sulfur (S) are major plant nutrients that enhance plant growth and development. Most of the plant nutrients (cations) tend to be less available when soil pH is above 7.5, and are optimally available at a slightly acidic pH in the range of 6.5 to 6.8..

We learned the various design reviews during the application life cycle. What is the role of DBA in each review stage? Who, other than DBA, should be involved at each stage and why? Do you think some of the design reviews may need to be reviewed again as a result of application development? Why or why not? Solution Design reviews are an important factor of the system development lifecycle for database applications. It is during the design review that all aspects of the database and application code are reviewed for efficiency, effectiveness, and accuracy. It is imperative that all database applications, regardless of their size, are reviewed to assure that the application was design properly, efficient coding techniques were used, and the database is accessed and modified correctly and efficiently. The design review is an important process for checking the validity of design decisions and correcting errors before applications and databases are promoted to production status. Multiple design reviews should be conducted throughout the application’s life. There are seven basic design review phases for a database application: There are many aspects of the development process and its resulting application that are addressed by design reviews. Some of the areas that can be addressed by a design review include: The DBA usually must act as the center point for organizing and conducting design reviews. If the DBA does not organize design reviews it is unlikely that any design review will be conducted. And if design reviews are not conducted, the application is more apt to suffer performance and availability problems in a production environment. A group consisting of subject matter experts and the developer’s peers and co-workers should conduct each design review. Formal design review roles should include the leader, the scribe, the mediator, and the participants. The leader can change from one design review to the next, but within the scope of a single design review a single leader must be assigned. The primary role of the leader is to act as a master of ceremonies to keep the review process moving along. Other duties include creating an agenda and ensuring that the agenda is followed, engaging all participants of the design review to solicit everyone’s input, ensuring that all participants maintain proper decorum, working with the proper participants before the meeting to ensure that all required documentation will be made available for the design review, and any other tasks necessary to ensure a successful design review. Though it is not mandatory, the DBA typically acts as the leader of design reviews for applications using a database. Thank you..

Steel can be strengthened by all but which of the following Annealing Quenching and tempering Age or precipitation hardening Work hardening Solution Sol: option A Steel can be strengthened by quenching or tempering, Precipitation hardening, work hardening. Steel can not be strengthened by Anneling process. 1) Anneling is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material to above its recrystallization temperature, maintaining a suitable temperature, and then cooling. In annealing, atoms migrate in the crystal lattice and the number of dislocations decreases, leading to the change in ductility and hardness. 2) Quench hardening is a mechanical process in which steel and cast iron alloys are strengthened and hardened. These metals consist of ferrous metals and alloys. This is done by heating the material to a certain temperature, depending on the material 3) Precipitation hardening, also called age hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some steels and stainless steels 4) Work hardening also known as strain hardening or cold working, is the strengthening of a metal by plastic deformation. This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material..
