A wide area network (also known as WAN), is a large network of information that is not tied to a single location. WANs can facilitate communication, the sharing of information and much more between devices from around the world through a WAN provider.

WANs can be vital for international businesses, but they are also essential for everyday use, as the internet is considered the largest WAN in the world. Keep reading for more information on WANs, their use, how they differ from other networks and their overall purpose for businesses and people, alike.

Della bought a gold plated watch belt for jim.

In "The Gift of the Magi," Jim and Della's apartment is an eight-dollar unit in a poor area of town and is sparsely furnished. The apartment is so small and meager that O. Henry does not go to great lengths describing the inside and leaves much to the reader's imagination. However, the reader is told that the Youngs have a "shabby little" couch and a thin mirror hanging between two windows.

Sandeep can speak Hindi fluently, but he can’t speak either Telugu or Tamil fluently Therefore Telugu speaking people talk to him in Hindi.

Our society comprises men and women. In earlier times, men were considered to be the leading members of a family. They were responsible for earning the livelihood and were the decision takers of the family. On the other hand, women were responsible for doing household work and upbringing of the children. So, the roles were mainly based on gender. There was no involvement of women in decision making. If we assess our entire sector, then research says that women’s issues are either focused on her reproductive role and her body or on her economic role as a worker. But none of them is focused on empowering the women.

What Does Women Empowerment Mean?
Women Empowerment is the process that creates power in women to live a happy and respectable life in a society. Women are empowered when they are able to access opportunities in a variety of fields such as in education, profession, lifestyle, etc., without any limitations and restrictions. It includes raising their status through education, awareness, literacy and training. It also includes the authority to take decisions. When a woman makes a crucial decision, she feels empowered.

Women’s empowerment is the most crucial point for the overall development of a country. Suppose, in a family, there is one earning person, while in another family, both men and women are earning, then who will have a better lifestyle. The answer is simple, the family where both men and women are earning money. Thus, the country where men and women work together develops at a faster rate.

Need for Women Empowerment
History says that women were ill-treated. The Sati Pratha in the ancient times to the girl child abortion in the present scenario, women continue facing such violence. Not only this, heinous crimes against women such as rape, acid attack, dowry system, honour killing, domestic violence, etc., are still happening in India.

Out of the total population, 50% of the population should consist of women. However, due to female foeticide practices, girl child numbers are decreasing sharply in India. It has also impacted the sex ratio in India. The literacy rate in girls is very low. Most of the girls are not even provided with primary education. Moreover, they are married early and made to raise children and shoulder only household work. They are not allowed to go out and are dominated by their husbands. Women are taken for granted by men as they are considered their property. Even at the workplace, women are discriminated against. They are paid less for the same work as compared to their male counterparts.

Steps to Empower Women
Women can be empowered in various ways. It can be done through government schemes as well as on an individual basis. At the individual level, we should start respecting women and start giving them opportunities equal to men. We should promote and encourage them to take up jobs, higher education, business activities, etc. The Government has come up with various schemes such as Beti Bachao Beti Padhao Yojana, Mahila-E-Haat, Mahila Shakti Kendra, Working Women Hostel, Sukanya Samriddhi Yojana, etc. to empower women. Apart from these schemes, we as individuals can also empower women by abolishing social evils like the dowry system, child marriage. These small steps will change the situation of women in society and make them feel empowered.

A variable which assumes a specific values in the given range discrete variable. 

Ex: Number of children/number of rooms in a college.

1. Errors of origin 

2. Errors of manipulation.

Source is written just below the foot note in a table, which indicate the data obtained from publications, books, journals etc. Footnote is to indicate the errors, ommissions, remarks, abrevations of the data in the table.

In a class, if in a class lower limit is included and upper limit is excluded but included in the next class is a exclusive class interval:

Ex: (0- 10), (10-20), (20-30).

Three ways of expressing the limits of the class intervals in a frequency distribution are namely exclusive method, inclusive method and true class limits.

x² + 7x + 4 = 0

Given that a & b are roots of this equation.

∴ a + b = -7

ab = 4

Now,

\(=\frac27a + \frac1{3.5}b + ab\)

\(=\frac{1}{3.5}(a+b)+ ab\)

\(= \frac1{3.5}\times -7 +4\)

\(= - 2 + 4\)

\(= 2.\)

The given function f(x) = ^7-xP_x-3 would be defined if
(i) 7 - x > 0 ⇒ x < 7
(ii) x - 3 > 0 ⇒ x > 3
(iii) (x - 3) < (7 - x)
⇒ 2x < 10 ⇒ x < 5
⇒ x = 3, 4, 5
Hence Range of f(x) = {⁴P₀, ³P₁, ²P₂}
Range of f(x) = {1, 3, 2}

X - Rays: have a wavelength just shorter than UV light.

Uses: Medical diagnosis, the study of crystal structures, radiotherapy.

Wavelength Range: 100Å to 0.1Å

Frequency Range: 10¹⁸ Hz to 10²⁰ Hz

Source: sudden deceleration of fast-moving electrons by the metal target.

Discovered by: Rontgen in 1895

Properties: effect on a photographic plate, ionization of gases, photoelectric effect, zero sense, more energetic than UV rays.

X-rays possess very short wavelengths that vary between 0.03 and 3 nanometers or between 0.02 Å and 100 Å;  however, some x-rays are small like a single atom of an element. 

Properties of X-Rays

X-rays with short wavelengths with high penetrating ability are highly destructive, that’s why they are called hard x-rays. 

The uses of X rays in medicinal purposes possess less penetrating power and have longer wavelengths and are called soft x-rays. X ray waves have a dual nature. We will now discuss the following properties of these radiations:

• They can cross the materials with more or unchanged.

• They are not easily refracted.

• These rays do not get affected by the electromagnetic field.

• X-rays ionize the surrounding air by discharging electrified bodies.

• They have very short wavelengths ranging from 0.1 A° to 1 A°. The velocity of X rays are similar to that of visible light, i.e., 186,000 miles/second or 300,000 kilometers/sec.

• X-rays are produced when a metallic anode is bombarded/broken by very high energy electrons.

• They can propagate independently, i.e., without any need of a medium.

• X-rays are diverging rays, i.e., they cannot be focused on a single point

• These radiations ar invisible, i.e., they cannot be heard or smelt

• They make a linear path in a free space but they do not carry an electric charge with them.

• They can cause photoelectric emissions.

• Intensity of X - rays rely on the number of electrons hitting the target.

• Continuous spectrum appears because of the retardation of electrons.

The combined gas law is also known as a general gas equation is obtained by combining three gas laws which include Charle's law, Boyle's Law and Gay-Lussac law.

The threshold frequency of metal plate P is lesser than that of Q.

Since λ∝ 1/ν, the threshold wavelength of metal plate P is greater than that of Q.

The work function of a metal is given as 
W₀ =hν₀

Since the threshold frequency of metal Q is greater, the work function it is also greater than that of P.

where \(\vec a\) = 2\(\hat i\) - 3\(\hat j\) - \(\hat k\)

\(\vec b=8\hat i-\hat j+3\hat k\)

\(\therefore\) Equation of required line is

= \((2\hat i-3\hat j-\hat k)\) + \(\lambda((8\hat i-\hat j+3\hat k)-(2\hat i-3\hat j-\hat k))\) 

 = \((2\hat i-3\hat j-\hat k)\) + \(\lambda((8-2)\hat i+(-1+3)\hat j+(3-(-1))\hat k)\) 

 = \((2\hat i-3\hat j-\hat k)\) + \(\lambda(6\hat i+2\hat j+4\hat k)\)

\(\vec B\) = \(4\hat i\) + \(9\hat j\) + \(2\hat k\)

\(\vec A \times \vec B\) = (\(3\hat i\) - \(3\hat j\) + \(\hat k\)) x ( \(4\hat i\) + \(9\hat j\) + \(2\hat k\))

= \(\begin{vmatrix}\hat i &\hat j &\hat k \\[0.3em]3 &-3 &1 \\[0.3em]4 & 9 & 2\end{vmatrix}\)

= \(\hat i\)(-3 x 2 - 9 x 1) - \(\hat j\)(3 x 2 - 4 x 1) + \(\hat k\)(3 x 9 - 4 x -3)

= \(\hat i\)(- 6 - 9) - \(\hat j\)(6 - 4) + \(\hat k\) (27 + 12)

=   \(-15\hat i\) - \(2\hat j\) + \(39\hat k\).

We have

\(\vec B\) = \(4\hat i\) + \(9\hat j\) + \(2\hat k\)

Ionic product 

1. It is applicable to all types of solutions. 

2. Its value changes with the change in con-centration of the ions.

Solubility product : 

1. It is applicable to the saturated solutions. 

2. It has a definite value for an electrolyte at a constant temperature.

The rate of a reaction increases with the increase in the concentration of the reactants. The effect of concentration is explained on the basis of collision theory of reaction rates. According to this theory, the rate of a reaction depends upon the number of collisions between the reacting molecules. Higher the concentration, greater is the possibility for collision and hence the rate.

The given statement states If you want to eat Chinese food, then you need to go to a restaurant. That means if you didn’t go to the restaurant. So you didn’t want to eat Chinese food. The only option that is equivalent to the given statement is option 1.

Hence, option 1 is the correct answer.

The correct answer is 1, 2 and 3.

• On March 12, 1930, Gandhiji lead a 241 miles march from Sabarmati to the coastal town of Dandi to defy British policy by making salt from seawater. Hence, Statement 1 is correct.
• Civil disobedience broke out all over India as a result of this act.
• Gandhiji was arrested on May 5 as a result of defying the British policy of Salt making.
• Gandhiji was released from prison in January 1931. 
• He agreed to call off the satyagraha in exchange for an equal negotiating role at a London conference on India’s future. Hence, Statement 3 is correct.
• In August 1931, Gandhiji travelled to the conference as the sole representative of the nationalist Indian National Congress.
• The meeting was a disappointment, but British leaders had acknowledged him as a force they could not suppress or ignore.
• Salt was chosen to symbolize the start of the civil disobedience movement because salt was deemed as something on which each Indian had the basic right.
• As a consequence of the No Tax Campaign, payment of chowkidari tax was refused. Hence, Statement 2 is correct.
  • Under Chowkidari Act 1856, police as allowed to collect tax from the peasants and provide funds to keep chowkidar in the villages. 
• The defiance of forest laws was noticed.

The correct answer is Pala.

• Uraiyur is an area of Tiruchirapalli in Tamil Nadu, India.
  • It was the capital of the early Cholas.
• Cheras were an ancient Dravidian dynasty of Tamil origin.
  • The location of the Chera capital is generally assumed to be at modern Karur.
• The capital of Pallavas was Kanchipuram.
  • Kanchipuram, also known as Kanchi, is an ancient city in southern India’s Tamil Nadu state. 
• The Pala Dynasty originated in the region of Bengal.
  • Hence it is not a South Indian dynasty.
