Methods of electrification  a)  Charging by friction Two glass rods rubbed with silk or wool cloth are brought close to each other, they repel each other  The two strands of wool or two pieces of silk cloth, with which rods were rubbed, also repel each other. However, the glass rod and wool attracted each other. Similarly, two plastic rods rubbed with cat's fur repelled each other but attracted the fur. On the other hand, the plastic rod attracts the glass rod and repel the silk or wool with which the glass rod is rubbed. The glass rod repels the fur....

 Welcome to study point Learn it Q1) Can we hear in space Ans-Sound needs a medium to travel, space is almost vaccum, so sounds can't travel in space, so we can't hear any sound  Did you know!   If sound travels through space then sounds from Sun can reach earth and it can cause worst effects on human hearing, because on Sun a lot of volcanic activities happening every minute, now we can image the sound of volcano eruptions travelling to earth then none of the humans can hear as every time there is unnecessary sound  Q2) How do aeroplanes fly  Ans- Aeroplanes work in a principle called  lift  it is about pressure difference, now I will tell what's lift When an aeroplane starts to run on runway then the air above the wings blow off , this creates a low pressure region above the wing and a high pressure at bottom, so due this pressure differences aeroplanes lift off, this maintains the balance of aeroplanes Did you know!  Aeroplanes change thei...

What is Indian Secularism?  The Indian Constitution mandates that the Indian State be secular. According to the Constitution, only a secular State can realise its objectives to ensure the following:  1. that one religious community does not dominate another;  2. that some members do not dominate other members of the same religious community;  3. that the State does not enforce any particular religion nor take away the religious freedom of individuals.  The Indian State works in various ways to prevent the above domination. First, it uses a strategy of distancing itself from religion. The Indian State is not ruled by a religious group and nor does it support any one religion. In India, government spaces like law courts, police stations, government schools and offices are not supposed to display or promote any one religion

 What is Secularism? Secularism refers to this separation of religion from the State. The Indian Constitution allows individuals the freedom to live by their religious beliefs and practices as they interpret these. In keeping with this idea of religious freedom for all, India also adopted a strategy of separating  the power of religion and the power of the State.  

 The first English factory was set up on the banks of the river Hugli in 1651. This was the base from which the Company’s traders, known at that time as “factors”, operated. The factory had a warehouse where goods for export were stored, and it had offices where Company officials sat. As trade expanded, the Company persuaded merchants and traders to come and settle near the factory. By 1696 it began building a fort around the settlement. Two years later it bribed Mughal officials into giving the Company zamindari rights over three villages. One of these was Kalikata, which later grew into the city of Calcutta or Kolkata as it is known today. It also persuaded the Mughal emperor Aurangzeb to issue a farman granting the Company the right to trade duty free. The Company tried continuously to press for more concessions and manipulate existing privileges. Aurangzeb’s farman, for instance, had granted only the Company the right to trade duty free. But officials of the Company, who were c...

 The Company Becomes the Diwan On 12 August 1765, the Mughal emperor appointed the East India Company as the Diwan of Bengal. The actual event most probably took place in Robert Clive’s tent, with a few Englishmen and Indians as witnesses. But in the painting above, the event is shown as a majestic occasion, taking place in a grand setting. The painter was commissioned by Clive to record the memorable events in Clive’s life. The grant of Diwani clearly was one such event in British imagination. As Diwan, the Company became the chief financial administrator of the territory under its control. Now it had to think of administering the land and organising its revenue resources. This had to be done in a way that could yield enough revenue to meet the growing expenses of the company. A trading company had also to ensure that it could buy the products it needed and sell what it wanted.

 In 1600, the East India Company acquired a charter from the ruler of England, Queen Elizabeth I, granting it the sole right to trade with the East. This meant that no other trading group in England could compete with the East India Company. With this charter the Company could venture across the oceans, looking for new lands from which it could buy goods at a cheap price, and carry them back to Europe to sell at higher prices. The Company did not have to fear competition from other English trading companies. Mercantile trading companies in those days made profit primarily by excluding competition, so that they could buy cheap and sell dear. The royal charter, however, could not prevent other European powers from entering the Eastern markets. By the time the first English ships sailed down the west coast of Africa, round the Cape of Good Hope, and crossed the Indian Ocean, the Portuguese had already established their presence in the western coast of India, and had their base in Goa....

 Bahadur Shah Zafar and his sons being arrested by Captain Hodson After Aurangzeb there was no powerful Mughal ruler, but Mughal emperors continued to be symbolically important. In fact, when a massive rebellion against British rule broke out in 1857, Bahadur Shah Zafar, the Mughal emperor at the time, was seen as the natural leader. Once the revolt was put down by the company, Bahadur Shah Zafar was forced to leave the kingdom, and his sons were shot in cold blood.

 Aurangzeb was the last of the powerful Mughal rulers. He established control over a very large part of the territory that is now known as India. After his death in 1707, many Mughal governors (subadars) and big zamindars began asserting their authority and establishing regional kingdoms. As powerful regional kingdoms emerged in various parts of India, Delhi could no longer function as an effective centre. By the second half of the eighteenth century, however, a new power was emerging on the political horizon – the British. Did you know that the British originally came as a small trading company and were reluctant to Facts on India

SOLAR SYSTEM Our planetary system is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids. Beyond our own solar system, we have discovered thousands of planetary systems orbiting other stars in the Milky Way. Beyond our own solar system, there are more planets than stars in night sky. So far, we have discovered thousands of planetary systems orbiting other stars in the Milky Way, with more planets being found all the time. Most of the hundreds of billions of stars in our galaxy are thought to have planets of their own, and the Milky Way is but one of perhaps 100 billion galaxies in the universe. While our planet is in some ways a mere speck in the vast cosmos, we have a lot of company out there. It seems that we live i...

 BIG BANG   Most astronomers believe the Universe began in a Big Bang about 14 billion years ago. At that time, the entire Universe was inside a bubble that was thousands of times smaller than a pinhead. It was hotter and denser than anything we can imagine. Then it suddenly exploded. The Universe that we know was born. Time, space and matter all began with the Big Bang. In a fraction of a second, the Universe grew from smaller than a single atom to bigger than a galaxy. And it kept on growing at a fantastic rate. It is still expanding today. As the Universe expanded and cooled, energy changed into particles of matter and antimatter. These two opposite types of particles largely destroyed each other. But some matter survived. More stable particles called protons and neutrons started to form when the Universe was one second old. Over the next three minutes, the temperature dropped below 1 billion degrees Celsius. It was now cool enough for the protons and neutrons to ...

  Internet , a system architecture that has revolutionized communications and methods of commerce by allowing various   computer networks   around the world to interconnect. Sometimes referred to as a “network of networks,” the Internet emerged in the United States in the 1970s but did not become visible to the general public until the early 1990s. By 2020, approximately 4.5 billion people, or more than half of the world’s population, were estimated to have access to the Internet. The Internet provides a capability so powerful and general that it can be used for almost any purpose that depends on information, and it is accessible by every individual who connects to one of its  constituent  networks. It supports human communication via social media,  electronic mail  (e-mail), “chat rooms,” newsgroups, and audio and video transmission and allows people to work collaboratively at many different locations. It supports access to digital information by many...
