Sometimes atoms gain or lose electrons. The atom then loses or gains a "negative" charge. These atoms are then called ions. Positive Ion - Occurs when an atom loses an electron (negative charge) it has more protons than electrons.

When the positive and negative charges grow large enough, a giant spark - lightning - occurs between thetwo charges within the cloud. This is like a static electricity sparks you see, but much bigger. Most lightninghappens inside a cloud, but sometimes it happens between thecloud and the ground.

HTML is a markup language, which is used to define the layout and attributes of a World Wide Web (WWW) document as well as to create links between Web pages.
HTML is the underlying foundation of Website design. It is a subset of SGML (Standard Generalised Markup Language) and a high-level markup language.
HTML is a short form of HyperText Markup Language, which means
(i) HyperText is simply a piece of text that has some extra features like formatting, images, multimedia and links to another document.
(ii) Markup Language is a way of writing layout information within documents. HTML is a page layout and hyperlink specification language. It allows images and other objects to be embedded that can be used to create interactive forms. HTML documents are described through HTML tags or elements.

To test if a body is charged or not, another uncharged body is brought in contact and seen whether the uncharged body is charged or not.

If a charged body (for example, ebonite rod) is touched to the metal disc of the gold-leaf electroscope, the metal strips of the electroscope gets charged by conduction. They repel each other and open up. In this way, we can detect whether an object is charged or not.

To designate an orbital n,l and m quantum numbers are required and s represents the (spin ) of the electron present in the orbital.

A non-volatile solute does produce vapour at the boiling point of the solution. They have lower vapour pressure and higher boiling point.

Example: Sugar.

A volatile solute produces vapour at the boiling point of the solution. At the same temperature, they have higher vapour pressure than non-volatile solutes.

Examples: Alcohol, ether, mercury, and gasoline.

The process of charging a body by bringing a charged body near it without touching it is called charging by induction. In this process, the body being charged acquires the opposite kind of charge to that of the body charging it.

Liberalism definition is - the quality or state of being liberal. How to use liberalism in a sentence. In the economic sphere, liberalism stood for the freedom of markets and the abolition of state- imposed restrictions on the movement of goods and capital. During the nineteenth century this was a strong demand of the emerging middle classes.

Plants play very important role on earth. They provide food and oxygen to all other living things. Plants are seen almost everywhere. They grow on land, on mountains, in deserts and under sea. We know plants grow mostly from seeds when they get enough water, sunlight and air.

The sky above Earth appears to rotate because of the rotation of the Earth. The apparent fixed stars go East to West as the Earth rotates West to East. But since the axis of rotation of Earth passes through pole star, it is that point about which the sky rotates and hence the pole star appears fixed.

Liberal Nationalism stood for many things- individual freedom, equality before the law, representative government & constitution as well as the inviolability of private property.

Liberal Nationalists in the economic sphere:

1. Liberalism stood for freedom of markets. They wanted to remove all restrictions of state on the movement of goods and capital.

2. Napoleon's regime had created different currencies, weights, measures and customs duties for each state. Liberalists wanted a unified economic territory.

3. A customs union from Prussia that was joined by many German states removed all tariffs and reduced the currencies from thirty to two.

4. The economic nationalism and unification further contributed to the nationalist sentiments.

Sun is nearer to earth as composed to distance of other stars from the earth, the sun appears to be bigger and brighter.

A group of autonomous computers and associated devices connected together by communication channels like cables or telephone lines etc. is called a network.
In a network, the computers work as stand alone machines but can communicate with other computers on the network as and when required.

CBSE Notes for Class 9 Foundation of Information Technology – Computer Networking

The last century was the century of Information Technology revolution. With the great breakthrough in the world of communication by the use of worldwide network of telephone lines, satellite launching and computers, the world has come very close. Sending a letter by post is virtually becoming obselete. Now is the time of e-mail, chats and video conferencing. All this has become possible because of networking.

A group of autonomous computers and associated devices connected together by communication channels like cables or telephone lines etc. is called a network.
In a network, the computers work as stand alone machines but can communicate with other computers on the network as and when required.

Types of Networks
There are mainly three types of networks as discussed below:
1. LAN (Local Area Network): A network spread over a diameter of minimum 1 m to maximum 10 km is called a local area network. It is usually installed within a building or a group of buildings.
2. MAN (Metropolitan Area Network): This type of network spans a small city. It is used by cable (TV) operators for program distribution.
3. WAN (Wide Area Network): This type of network spans an entire country and very often several countries. The speed of data transmission is a bit slower than that of LAN and the error rate is also high as the data has to travel over very long distances.

In Maths, integers are the numbers which can be positive, negative or zero, but cannot be a fraction. 

The examples of integers are, 1, 2, 5,8, -9, -12, etc. The symbol of integers is “Z“.

< EC takes decisions on every aspect of conduct and control of elections from the announcement of elections to the declaration of results. < It implements the Code of Conduct and punishes any candidate or party that violates it. < During the election period, the EC can order the government to follow some guidelines, to prevent use and misuse of governmental power to enhance its chances to win elections, or to transfer some government officials. < When on election duty, government officers work under the control of the EC and not the government.

Tangents drawn from am external point to a circle 

are equal in length

so from the diagram we get

AH​= AE​; DH = DG; CG​=CF​
4−x=x                            y=2y−3
2x=4                                 y=3​

x=2​

As x=2    DH = 5 − AH = 5−(4−x)  =3

as DH=DG   DG=3

So Length of CD=CG+GD

=3+3=6

Narendra Damodardas Modi is an Indian politician serving as the 14th and current Prime Minister of India since 2014.

Lencho was a farmer. He was not so poor and not so rich farmer. He was having a great faith in God. This we came to know from his letter addressed to God. He did so for the compensation of his crops. Actually the hail stones destroyed his crops and he thought that now his family would starve throughout the whole year. But he was very religious person, so he decided to ask the God for his help. In his letter to God he asked the God for 100 pesos. But his letter was not reached to God. It were the post office employees who sent the 70 pesos for help. And Lencho called the post office employees as “a bunch of crooks”. While they helped him. Because of this we can say that Lencho was a foolish person too (in the sense of innocence).

The name of person who led a new religious movement in Karnataka was Basavanna (1106 - 68). His followers was known as Virashaivas (heroes of Shiva) or Lingayats (wearers of the linga). They worship Shiva in his mani festation as a linga and men usually wear a small linga in a silver case on a loop strong over the left shoulders.

Alvars were devotees of Vishnu and Nayanars were devotees of Shiva. They travelled from one place to another singing in praise of their Gods. Chola kings supported them by giving them land and grants. The temple at Chidambaram, Thanjavar and Gangaikanda Cholapuram were constructed under their patronage.

Two earliest Bhakti movements of Tamii Nadu were the Alvars and the Nayanars . Some of the earliest Bhakti movements (C. sixth century) were led by the Alvars (literally) those who are “immersed” in devotion to Vishnu) and Nayanars (literally, leaders who were devotees of Shiva). They travelled from place to place singing hymns in Tamil in praise of their gods.
