1. Stability: It ensures stability, in the international money market/ exchange market. Day to day fluctuations are avoided. It helps formulation of long term economic policies, particularly relating to exports and imports. 

2. Encourages international trade: Fixed exchange rate system implies low risk and low uncertainty of future payments. It encourages international trade. 

3. Co-ordination of macro policies:Fixed exchange rate helps co¬ordination of macro policies across different countries of the world. Long term economic policies can be drawn in the area of international trade and bilateral trade agreements.

Financial accounting deals with Determination of profit

Appreciation of domestic currency means a rise in the price of domestic currency (say, rupee) in terms of a foreign currency (say, $). Now, one rupee can be exchanged for more $, i.e., with the same amount of money, more goods can be purchased from the USA. It leads to increase in imports from the USA as American goods will become relatively cheaper.

Appreciation of domestic currency means lower price of foreign currency in terms of domestic currency. This increases the price of domestic goods for foreign buyers. This means imports become cheaper. As a result the demand for imports may rise. 

Example: 1$ = 60 Rs is changed to 1$ = 55 Rs. It is appreciation of domestic currency & now importing 1 dollar good has become cheaper so import will increase.

GET and POST.

GET and POST are the only HTTP methods to use when dealing with forms. Django's login form is returned using the POST method, in which the browser bundles up the form data, encodes it for transmission, sends it to the server, and then receives back its response.

Both of these are dictionary-like objects that give you access to GET and POST data. POST data generally is submitted from an HTML, while GET data can come from a or the query string in the page's URL.

Degree : It is the total number of attributes in the table.

Cardinality: It is the total number of tuples in the table

A Candidate Key can be any column or a combination of columns that can qualify as unique key in database. There can be multiple Candidate Keys in one table where as A Primary Key is a column or a combination of columns that uniquely identify a record. Only one Candidate Key can be Primary Key. 

DESC  is used to sort the records of a table in descending order.

DISTINCT  is used to remove the duplicating rows of the table.

ORDER  BY keyword is used to sort the records of a table

The method of arranging data into homogeneous classes according to some common features present in the data is called classification.

According to Horace Secrist, "Classification is the process of arranging data into sequence and groups according to their common characteristics or separating them into different but related parts.

These are following objectives of classification:

• To consolidate the volume of data in such a way that similarities and differences can be quickly understood. Figures can consequently be ordered in a few sections holding common traits.
• To aid comparison.
• To point out the important characteristics of the data at a flash.
• To give importance to the prominent data collected while separating the optional elements.
• To allow a statistical method of the material gathered.

Alink stands for active link while vlink stands for visited link. When the cursor is positioned on the hyperlinked text, the coloured specified in alink attribute (red) is seen. When the link has been clicked once, the colour changes to the one specified in vlink attribute ( yellow).

(i) Cockroach belongs to phylum-Arthropoda and is a terrestrial organism.
Its body is protected by an exoskeleton made up of hard substance called chitin. This exoskeleton protects the cockroach from any harm.

(1) If you have been stung by a honey bee, the sting leaves an acid which causes pain and irritation

(2) Use of a mild base like baking soda on the stung area gives relief.

(3) Stinging hair of leaves of nettle plant, inject methanoic acid or formic acid causing burning pain.

Absolute refractive index of a medium is defined as the ratio of the velocity of light in a vacuum to the velocity of light in the medium. If c is the velocity of light in vacuum and v in the medium, then:

 n = c/v

Absolute refractive index = Speed of light in vacuum /Speed of light in medium

According to question,
For A,
Speed of light in vacuum / Speed of light in medium A = na  .......(i)

For B,
Speed of light in vacuum / Speed of light in medium B = nb    .......(ii)

Dividing (ii) by (i),

nb /na=Speed of light in medium A/Speed of light in medium B

Now, refractive index of medium 'B' with respect to medium 'A=Speed of light in medium A/Speed of light in medium B = nb/na = b/a

Optical density of a medium is the measure of its transmittance for a radiation of particular wavelength. Higher is the value of optical density, lower is transmittance. it is expressed as log10 (1/T), where T is the transmittance in percentage (T = I/10).

And also a higher value of refractive index means higher optical density. This means that light travels slower, in a medium with high optical density. Speed of light slows down in a optically denser because light interacts with the matter inside the denser medium.
