Properties of Ionic compound:

• Ionic compounds are solid. Ionic bond has greater force of attraction because of which ions attract each other strongly. This makes ionic compounds solid.
• Ionic compounds are brittle.
• Ionic compounds have high melting and boiling points because force of attraction between ions of ionic compounds is very strong.
• Ionic compounds generally dissolve in water.
• Ionic compounds are generally insoluble in organic solvents; like kerosene, petrol, etc.
• Ionic compounds do not conduct electricity in solid state.
• Solution of ionic compounds in water conduct electricity. This happens because ions present in the solution of ionic compound facilitate the passage of electricity by moving towards opposite electrodes.
• Ionic compounds conduct electricity in molten state.

 (i) Hand Printing : The earliest kind of print technology was developed in China, Japan and Korea. This was a system of hand printing. From AD 594 onwards, books in China were printed by rubbing paper – also invented there- against the inked surface of woodblocks. As both sides of the thin, porous sheet could not be printed, the traditional Chinese ‘accordion book’ was folded and stitched at the side. Superbly skilled craftsmen could duplicate, with remarkable accuracy, the beauty of calligraphy.
(ii) Major producer : The imperial state in China was, for a very long time, the major producer of printed material. China possessed a huge bureaucratic system which recruited its personnel through civil service examinations. Textbooks for this examination were printed in vast numbers under the sponsorship of the imperial state. From the sixteenth century, the number of examination candidates went up and that increased the volume of print.
(iii) Printing in the 17th century : By the seventeenth century, as urban culture bloomed in China, the uses of print diversified. Print was no longer used just by scholar officials. Merchants used print in their everyday life, as they collected trade information. Reading increasingly became a leisure activity. The new readership preferred fictional narratives, poetry, autobiographies, anthologies of literary masterpieces, and romantic plays. Rich women began to read, and many women began publishing their poetry and plays. Wives of scholar-officials published their works and courtesans wrote about their lives.
(iv) Printing in the 19th century : This new reading culture was accompanied by a new technology. Western printing techniques and mechanical presses were imported in the fate nineteenth century as Western powers established their outposts in China. Shanghai became the hub of the new print culture, catering to the Western-style schools. From hand printing there was now a gradual shift to mechanical printing.

There are four types of English sentence, classified by their purpose:

• declarative sentence (statement)
• interrogative sentence (question)
• imperative sentence (command)
• exclamative sentence (exclamation)

2	interrogative	question: It asks us something	Does Mary like John?	?
3	imperative	command: It tells us to do something	Stop! Close the door.	! or .
4	exclamative	exclamation: It expresses surprise	What a funny story he told us!	!

Given,

or

escape speed is given as

v = (2GM / R)^1/2

here

M is the mass of the planet

R is the radius of the planet

 

now, for Mars

v_m = (2GM_m / R_m)^1/2

for earth

v_e = (2GM_e / R_e)^1/2 = 11.2 km/s

we are given

M_m = M_e/9

and R_m = R_e/2

thus, we have

v_m = (2GM_m / R_m)^1/2 =  (2G(M_e /9) /  (R_e/2))^1/2

or

v_m = (2/9)^1/2 . (2GM_e / R_e)^1/2 = (2/9)^1/2.v_e

thus,

v_m = 0.4714 x v_e

or

v_m = 0.4714 x 11.2

so, the escape speed of Mars will be

v_m = 5.27 km/s

= 7.47 km/sec.

Science

As, it is given that   k   ^th   term of the A.P.  is 5k   + 1.

therefore,

  a_k   =   a   + (k   – 1)d

⇒   a   + (k   – 1)d   = 5k   + 1

⇒ a   +   kd   –   d   = 5k   + 1

now, on comparing the coefficient of   k, we get,

d = 5

and 

 a   –   d   = 1

⇒   a   – 5 = 1

⇒   a   = 6

Hello I you

(i)    Mughal government was a monarchy. The emperor was all-in-all having all executive, legislature and judiciary powers in himself. He was chief commander of the forces. The position of all ministers were just the government officials of the present day government.

(ii)    Though empire was divided in certain provinces, parganas, districts and villages, yet the all governors were appointed by emperor himself.

(iii) The change of the government was not done by the people as it is done by voters today.

Generally succession was either decided by the emperor or the major courtiers or on the basis of sword of might. The Mughal rulers saw themselves as appointed by Divine will. Now-a-days after every five year or even earlier the head of the state i.e. the president or the head of real administration or government is change by the public through ballot. During the Mughal period sometime throne was smashed by force. The example is of Shershah, who has defeated Humayun and force him leave Hindustan. After the gap of fifteen years he defeated the successor of Shershah and again got his throne. The authority of Akbar, Jahangir and even Shah Jahan was challenged by their own sons or blood relations.

Different festivals which are celebrated in my locality are; Holi, Diwali, Eid, Christmas, Rath Yatra, Chhath, Guru Parb, etc. Holi and Diwali are Hindu festivals which are celebrated all over India. In my locality, my Muslim and Christian friends also participate in these festivals. Similarly, Hindus and Sikhs also participate in Christmas and Eid. I have seen most of my Hindu friends wearing the Santa Clause cap during Christmas. Rath Yatra is mainly celebrated in Orissa. But in my locality, when people from Orissa take out the procession; everyone from the neighbourhood participate in that. Chhath is mainly celebrated in Bihar and Eastern UP. But in my locality, most of the people throng the venue of Chhath Puja.

This is a very big answer please aap mujhe Chhota karke de dijiye

On July 7, HRD Minister Ramesh Pokhriyal announced a major CBSE syllabus reduction with 30% of the syllabus slashed for the year 2020-21 for classes 9 to 12 because of the reduction in classroom teaching time due to the Covid-19 pandemic and lockdown.

CBSE has rationalized the syllabus with the help of suggestions from NCERT and the same has been notified by a new CBSE notification as well.

The CBSE syllabus has been reduced but care has been taken so that the learning outcomes remain the same and the students do not miss out on learning core concepts in various subjects.

yes the address is suitable title for the story written by margo minco because the whole story is about the address of mrs Dorling marconi street house number 46

Margo Minco has very aptly and logically titled this short story ‘The Address’. The narrator and her mother were victims of the war. The upheaval forced them to be wanderers. They had no permanent address worth the name. All the ‘nice things’ were at No. 46, Marconi Street. They aroused nostalgic feelings of former times. But their true owner was no more in the world. The narrator resolved to forget them and also the address where they lay.

• The transformation of Great Britain into a nation state was not a sudden process. There was no one British nation before the eighteenth century.
• People residing in the British Isles were mainly English, Welsh, Scots and Irish. These ethnic groups had distinct political and social traditions.
• As the English nation grew in wealth and power, it began to dominate the other islands.
• In 1688, the English Parliament seized power from the monarchy. The Parliament passed the Act of Union, 1707, by which England and Scotland were unified resulting in the formation of the ‘United Kingdom of Great Britain’.
• The Parliament was dominated by the English, and the political and cultural identities of the Scots were systematically suppressed. The Catholics in Scotland were brutally suppressed whenever they wanted to regain their independence.
• Ireland was inhabited by the Protestants and the Catholics. The English supported the Protestants and established their rule with their help and support. Catholics, who constituted a majority in Ireland, revolted against the British on numerous occasions but were suppressed.
• Ireland forcibly became a part of Britain in 1801. The English language dominated, and both Scotland and Ireland were subordinate to England.

This is a strange case because the formation of nation states in Great Britain was not a result of a sudden upheaval or revolution. It was rather a result of long-drawn-out process.
