F=10cm

R=20cm We know that, F=r/2 Now, F=20/2 F= 10cm

Radius of Curvature,R= 20 cm We know that , R=2f R/2 = f .....(1) Putting the value of R in eq.(1), we get, 20/2 = f f = 10 cm Therefore, focal length of sperical mirror having radius of curvature= 20cm is 10cm

Man is a product of circumstances and environment. Hari Singh was just a boy of fifteen but was an experienced and fairly a successful hand. Circumstances made him a thief. In spite of being no use to Anil, he was retained to work for him. They say old habits die hard. After all, a thief couldn’t leave stealing and cheating. He made a rupee every day from the buying of the day’s supplies. However, Anil was not a fool. He knew everything and also all about the theft. But he was kind, large-hearted and full of human sympathy. He taught the unfortunate boy to write his name. Ile also promised him to write sentences and add numbers. This left a deep impression on the boy-thief. lie started realising that education could bring him respect and money.

Hari Singh breached Anil’s trust but Anil was all forgiving and compassionate. In the heat and excitement of theft, Hari Singh forgot about education. Then came the true realisation and transformation. The boy-thief realised that the only man who could help him was the man he had robbed a few hours ago. Then he realised the value of education that could give him respect and more money than he could get by stealing. He realised where he should go. Large-hearted Anil not only forgave him but also gave him a fifty-rupee note, and promised to pay him regularly.

Chemical reactions can be classified in following types: Combination Reaction Decomposition Reaction Displacement Reaction Double Displacement Reaction Oxidation and Reduction Reaction Combination Reaction: Reactions in which two or more reactants combine to form one product are called COMBINATION REACTION. A general combination reaction can be represented by the chemical equation given here. A + B ⇨ AB Example: When magnesium is burnt in air (oxygen), magnesium oxide is formed. In this reaction, magnesium is combined with oxygen. Mg + O2 ⇨ 2MgO Magnesium + Oxygen ⇨ Magnesium oxide When carbon is burnt in oxygen (air), carbon dioxide is formed. In this reaction, carbon is combined with oxygen. C + O2 ⇨ CO2 Carbon + Oxygen ⇨ Carbon dioxide When hydrogen reacts with chlorine, hydrogen chloride is formed. H2 + Cl2 ⇨ 2HCl Hydrogen + Chlorine ⇨ Hydrogen chloride When calcium oxide reacts with water, calcium hydroxide is formed CaO + H2O ⇨ Ca(OH)2 Calcium oxide + Water ⇨ Calcium hydroxide When carbon monoxide reacts with oxygen, carbon dioxide is formed. 2CO + O2 ⇨ 2CO2 Carbon monoxide + Oxygen ⇨ Carbon dioxide Decomposition Reaction: Reactions in which one compound decomposes in two or more compounds or element are known as DECOMPOSITION REACTION. Decomposition reaction is just opposite of combination reaction. A general decomposition reaction can be represented as follows: AB ⇨ A + B Example: When calcium carbonate is heated, it decomposes into calcium oxide and carbon dioxide CaCO3 ⇨ CaO + CO2 Calcium carbonate ⇨ Calcium oxide + Carbon dioxide When ferric hydroxide is heated, it decomposes into ferric oxide and water 2Fe(OH)3 ⇨ Fe2O3 + 3H2O Ferric hydroxide ⇨ Ferric oxide + Water When lead nitrate is heated, it decomposes into lead oxide, nitrogen dioxide and oxygen. 2Pb(NO3)2 ⇨ 2PbO + 4NO2 + O2 Lead nitrate ⇨ Lead oxide + Nitrogen oxide + Oxygen In above examples, compound is decomposed because of heating, so, these reactions are called THERMAL DECOMPOSITION REACTION.

Chemical reactions can be classified in following types:

• Combination Reaction
• Decomposition Reaction
• Displacement Reaction
• Double Displacement Reaction
• Oxidation and Reduction Reaction

Combination Reaction: Reactions in which two or more reactants combine to form one product are called COMBINATION REACTION.

A general combination reaction can be represented by the chemical equation given here.

<i>A + B ⇨ AB</i>

<hr />

Example: When magnesium is burnt in air (oxygen), magnesium oxide is formed. In this reaction, magnesium is combined with oxygen.

<i>Mg + O₂ ⇨ 2MgO</i>

<i>Magnesium + Oxygen ⇨ Magnesium oxide</i>

When carbon is burnt in oxygen (air), carbon dioxide is formed. In this reaction, carbon is combined with oxygen.

<i>C + O₂ ⇨ CO₂</i>

<i>Carbon + Oxygen ⇨ Carbon dioxide</i>

When hydrogen reacts with chlorine, hydrogen chloride is formed.

<i>H₂ + Cl₂ ⇨ 2HCl</i>

<i>Hydrogen + Chlorine ⇨ Hydrogen chloride</i>

When calcium oxide reacts with water, calcium hydroxide is formed

<i>CaO + H₂O ⇨ Ca(OH)₂</i>

<i>Calcium oxide + Water ⇨ Calcium hydroxide</i>

When carbon monoxide reacts with oxygen, carbon dioxide is formed.

<i>2CO + O₂ ⇨ 2CO₂</i>

<i>Carbon monoxide + Oxygen ⇨ Carbon dioxide</i>

<hr />

Decomposition Reaction: Reactions in which one compound decomposes in two or more compounds or element are known as DECOMPOSITION REACTION. Decomposition reaction is just opposite of combination reaction.

A general decomposition reaction can be represented as follows:

<i>AB ⇨ A + B</i>

Example: When calcium carbonate is heated, it decomposes into calcium oxide and carbon dioxide

<i>CaCO₃ ⇨ CaO + CO₂</i>

<i>Calcium carbonate ⇨ Calcium oxide + Carbon dioxide</i>

When ferric hydroxide is heated, it decomposes into ferric oxide and water

<i>2Fe(OH)₃ ⇨ Fe₂O₃ + 3H₂O</i>

<i>Ferric hydroxide ⇨ Ferric oxide + Water</i>

When lead nitrate is heated, it decomposes into lead oxide, nitrogen dioxide and oxygen.

<i>2Pb(NO₃)₂ ⇨ 2PbO + 4NO₂ + O₂</i>

<i>Lead nitrate ⇨ Lead oxide + Nitrogen oxide + Oxygen</i>

In above examples, compound is decomposed because of heating, so, these reactions are called THERMAL DECOMPOSITION REACTION.

The Frankfurt Parliament was convened at the Church of St. Paul in Frankfurt.

Extra explanation:

The Frankfurt Parliament: It was an all-German National Assembly formed by the middle-class professionals, businessmen and prosperous artisans belonging to the different German regions. It was convened on 18 May, 1848 in the Church of St. Paul, in the city of Frankfurt. This assembly drafted a constitution for a German nation to be headed by a monarchy subject to a parliament. However, it faced opposition from the aristocracy and military. Also, as it was dominated by the middle classes, it lost its mass support base. In the end, it was forced to disband on 31 May, 1849.

Respected Sir/Madam,

Subject: Steps towards taking necessary steps to preserve our beautiful bio-reserves.

My name is _________. Firstly, I would like to apologize for taking out your precious time in reading my letter. I would want to draw your kind attention of the anxious authorities toward the falling bio-reserves of our multi-cultural country through this column of your prestigious newspaper.
India has about 2.4 percent of the world’s area, but it has only eight percent of the world’s bio-reserves. India is one of the 12 most diverse region in the whole entire world. There are over 47,000 different, colourful species of plants and over 89,000 furious species of animals. Even though of all of these, our majestic flora and fauna at our natural country are in a huge treat due to Human Activities. The technology is developing in our vast country. Over population is occurring! Pollution has led to lesser availability of sources of drinking water. Deforestation is happening over the few years for resources of us humans. Plants are dying, animals are getting extinct, and we are not taking any serious actions on these on-going problems. We have to relook into these major issues so that India can have a brighter and better future.

You are requested to kindly look into the matter and respond to it immediately. Strict actions need to be taken for the same. Thanking you!

Yours truly, ___________

Here A (6,3 ) and B(-2,-5) Now by x axis it is being divided so the point of intersection of AB and x axis let P(x,0) Let the ratio be k:1 Now x = k(-2)+1(6)/k+1 =-2k +6/k+1 Also 0 = k(-5)+1(3)/k+1 -5k +3 = 0 k = 3/5 So the ratio is 3:5 Now point P (x,0) here x = -2(3)+6(5)/3+5 = -6+30/8 = 24/8 =3 So the point P (3,0) and ratio is 3:5.

3Fe + 4H2O -> Fe3O4 + 4H2 You can always balance equations by following a sequence : MINHO= metals, ions, non-metals, hydrogen, oxygen.

The future of our planet is in danger. The current types and levels of development are not sustainable as these are over exploiting natural resources and depleting the environment. if the resources continue to be exploited by a few greedy individuals, it would lead to various socio-economic and environmental issues. There is need for sustainable development, that is, current development does not compromise with the needs of the future generations.

The human excretory system comprises of the following structures: two bean-shaped kidneys, two ureters, one urinary bladder, and one urethra. 

Kidneys are the main organ of the human excretory system. The kidneys are paired organs and are located one on each side of the spine at the level of the liver. They are divided into three regions- the renal cortex which is the outer layer, the renal medulla which is the inner layer and the renal pelvis which is responsible for carrying the urine from the kidney to the ureter. The functional unit of a kidney is called the nephron.

There is one ureter that comes out of each kidney as an extension of the renal pelvis. The ureter is a thin muscular tube that carries urine from the kidneys to the bladder.

The bladder receives urine from the ureters, one from each kidney. It is a sac-like structure that is lined with smooth muscle layer and is responsible for storage of urine till it is expelled from the body by micturition (urination).

The urethra is a tube that arises from the urinary bladder and expels urine by micturition. The urethra is shorter in females and longer in the males. In males, the urethra functions as a common path for sperms and urine. The opening of the urethra is guarded by a sphincter that is voluntary.

Thank you all

due to too many and higer refractive index

The refractive index of diamond is very high. When enter in it and it bend then speed of light is low in so it shine

Its due to Total internal reflection (TIR) . When the light rays enter diamond it acts as a prism and disperses the light in its seven constituent colours and after when these colours strike the others surface of diamond TIR takes place and then after emerging the white light again combines into white light and we see the diamonds as if they are sparkling

Read the book first of all and then see some video of that particular chapter and again read the book

1. Once read the chapters carefully. 2.again read the chapter and simultaneously make notes.
