To make a kaleidoscope, get three rectangular mirror strips. Join them together to form a prism. Fix them in a circular cardboard tube or tube of a thick chart paper. Make sure that the tube is slightly longer than the mirror strips. Close one end of the tube by a cardboard disc having a hole in the centre, through which you can see At the other end, touching the mirrors, fix a circular plane glass plate. Place on this glass plate several small pieces of coloured glass. Close this end of the tube by a ground glass plate. Allow enough space for the colour pieces to move around. Your kaleidoscope is ready. When you peep through the hole, you will be able to see a variety of patterns in the tube. Interesting feature of a kaleidoscope is that you will never see the same pattern again.

what are the application of electroplating

Posted by Shah Munazil 5 years, 3 months ago

Applications of Electroplating

Artificial jewelry, usually made of less expensive metals is often plated with a thin layer of a precious metal like gold and silver to make it more lustrous, appealing but cheaper.
Many industrial applications use electroplating to create a protective barrier on a metal substrate. The protective barrier in this case prevents tarnishing and gives a glossy appearance. Eg: Chromium plating is done on car spare parts, taps, wheel rims etc. Chromium is very expensive and the whole part cannot be made of chromium. So, it is coated with chromium to give it a shiny appearance.
Tinning (electroplating of tin) is a very cost-effective electroplating solution. Tin is relatively cheaper and is used for electroplating electronic components, hardware products, fasteners, screws, nuts, bolts and food cans. If food is stored in iron cans, it would tend to get spoilt over a period of time. But, when iron is electroplated with tin, it prevents the food from getting spoilt. Tinning offers resistance against corrosion
Zinc electroplating offers excellent adhesion and resistance to corrosion. So, it is used to electroplate automobile parts and body, transmission components, defense carriers and tanks.

Applications of electroplating Electroplating is widely used in numerous sectors for coating metal objects with a thin layer of a different metal. The added metal has a desired property the original object lacks and is primarily used to improve corrosion resistance. Chromium plating is a great example.

This article is about the Mughal emperor. For other uses, see Akbar (disambiguation). Abu'l-Fath Jalal-ud-din Muhammad Akbar[7] (Persian: ابو الفتح جلال الدين محمد اكبر; October 1542[a]– 27 October 1605),[10][11] popularly known as Akbar the Great,[12] (Akbar-i-azam اکبر اعظم), and also as Akbar I (IPA: [əkbər]),[13] was the third Mughal emperor, who reigned from 1556 to 1605. Akbar succeeded his father, Humayun, under a regent, Bairam Khan, who helped the young emperor expand and consolidate Mughal domains in India. Jalal-ud-din Muhammad Akbar جلال الدین محمد اکبر Badshah of the Mughal Empire Akbar the Great Govardhan.

His power and influence, however, extended over the entire subcontinent because of Mughal military, political, cultural, and economic dominance. To unify the vast Mughal state, Akbar established a centralised system of administration throughout his empire and adopted a policy of conciliating conquered rulers through marriage and diplomacy. To preserve peace and order in a religiously and culturally diverse empire, he adopted policies that won him the support of his non-Muslim subjects. Eschewing tribal bonds and Islamic state identity, Akbar strove to unite far-flung lands of his realm through loyalty, expressed through an Indo-Persian culture, to himself as an emperor. Mughal India developed a strong and stable economy, leading to commercial expansion and greater patronage of culture. Akbar himself was a patron of art and culture. He was fond of literature, and created a library of over 24,000 volumes written in Sanskrit, Urdu, Persian, Greek, Latin, Arabic and Kashmiri, staffed by many scholars, translators, artists, calligraphers, scribes, bookbinders and readers. He did much of the cataloging himself through three main groupings.[14] Akbar also established the library of Fatehpur Sikri exclusively for women,[15] and he decreed that schools for the education of both Muslims and Hindus should be established throughout the realm. He also encouraged bookbinding to become a high art.[14] Holy men of many faiths, poets, architects, and artisans adorned his court from all over the world for study and discussion. Akbar's courts at Delhi, Agra, and Fatehpur Sikri became centres of the arts, letters, and learning. Timurid and Perso-Islamic culture began to merge and blend with indigenous Indian elements, and a distinct Indo-Persian culture emerged characterized by Mughal style arts, painting, and architecture. Disillusioned with orthodox Islam and perhaps hoping to bring about religious unity within his empire, Akbar promulgated Din-i-Ilahi, a syncretic creed derived mainly from Islam and Hinduism as well as some parts of Zoroastrianism and Christianity. Akbar's reign significantly influenced the course of Indian history. During his rule, the Mughal Empire tripled in size and wealth. He created a powerful military system and instituted effective political and social reforms. By abolishing the sectarian tax on non-Muslims and appointing them to high civil and military posts, he was the first Mughal ruler to win the trust and loyalty of the native subjects. He had Sanskrit literature translated, participated in native festivals, realising that a stable empire depended on the co-operation and good-will of his subjects. Thus, the foundations for a multicultural empire under Mughal rule were laid during his reign. Akbar was succeeded as emperor by his son, Prince Salim, later known as Jahangir.

Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements. In normal conditions oxygen is a colourless, odourless and insipid gas; it condensates in a light blue liquid. Oxygen is part of a small group of gasses literally paramagnetic, and it's the most paramagnetic of all. Liquid oxygen is also slightly paramagnetic. A yellowy-green dense gas with a choking smell. Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water. It is also used to make hundreds of consumer products from paper to paints, and from textiles to insecticides.

1 answers

Yogita Ingle 5 years, 3 months ago

In 1817, James Mill, a Scottish economist and a political philosopher, published A History of British India in three volumes. He divided Indian history into three periods—Hindu, Muslim and British. It has been argued by many historians that it is not correct to periodise Indian history on the basis of religion of the rulers. For example, when the Hindu kings ruled in ancient India, many religions existed peacefully. The same is also true for mediaeval India. It was not correct to periodise mediaeval India as Muslim History because people belonging to different faiths existed during this time. Such periodisation which was based on the religion of the rulers suggests that the lives, practices and culture of the other people do not matter.

The species which are facing the risk of extinction are called endangered species.

They are the animals and plants that exist in small number on the earth, and if we do not take quick action to save them, they may be lost for ever.

An animal species become endangered either because it is few in number or it is being killed by predators or it is being hunted by human beings or its natural habitat is destroyed by deforestation.
