Characters are a part of stage setting. This reflects in ‘A Midsummer Night’s Dream’ from the Duke in the palace as he instructs Philostrate to arrange for the celebration with great revelry. However, in the another part of the wood Oberon and Titania struggle for the custody of the Indian boy. Oberon uses love potion on the eyelids of Titania when she sleeps. As the setting of the stage changes the characters change accordingly. Because of the presence of the fairies and an Indian boy, the characters in the play range from real to imaginary.

The song is sung by Bottom to try to keep his courage up as Puck has just turned his head into that of an ass. This transformation scared everyone around him and he is alone in the forest. But his song awakens Titania who falls in love with him immediately and the use of appropriate words and songs are there for the other parts of the wood also.

A Midsummer Night’s Dream is a comedy of errors.

As per the requirement of the play ‘A Midsummer Night’s Dream’ the versality and the aptness of the stage setting go hand in hand. The play starts in the palace and then the stage of the play develops in two different parts of the wood. The stage-setting has been arranged according to the need of the characters and the plot. The characters are set accordingly onto the stage.

Many authors have tried to potray love as human nature, however, none could display it better than Shakespeare does in his plays. In this play – ‘A Midsummer Night’s Dream’ he explains human nature of ‘control’ through love. He has given a clear picturisation of how love controls a person in the character of Theseus as he forgives Hermia and allows her to marry her love Lysander. It reveals that true love prevails and finds solace.

Shakespeare also explains human nature of conflicts between family and friends. He gives a clear picturisation of conflict when the magic potion ‘Love in Idleness’ was wrongly used on Lysander and he falls in love with Helena because of which Hermia and Helena start a quarrel. Another conflict potrayed, is between the family, when Hermia is given three choices by her father – marry Demetrius, become a nun or die to which she rebels against her father and decides to elope to the woods to marry her love Lysander. Hence, Shakespeare is acknowledged as the greatest writer of human nature.

A Midsummer Night’s Dream is one of the best examples of Shakespear’s comedy of errors because it has all the features of comedy of errors like conflict between characters, resolution over the problem, cleared confusions between the love triangle, reunion and marriage. It all seem very funny and interesting.

Oberon was jealous of his queen Titania because she refused to give the boy to him . She fell in love with Bottom. Oberon decided to seek revenge on his queen. It was Oberon himself who made Titania to fall in love with Bottom who was having the head of a donkey. Comic incident was created by that scene in the drama.

When someone is in a better position of money or success or fame, there are people who feel that they should destroy that. This is jealousy. We can see people who have more, and we can also work hard to reach that position. But when someone wants to destroy that person who has reached the better position that is wickedness. The jealous person is not willing to work for that state. They will not accept a lesser place also. So a jealous mind-set slowly becomes completely evil.

A desert is defined as an arid region characterized by extremely high or low temperatures, and very low rainfall. These extreme climatic conditions are not suitable for flora, hence, there is scanty vegetation in the deserts.

The altitude in Ladakh varies from about 3000 to 8000 m. Due to its high altitude, the climate is extremely cold and dry. Moreover, the air at this altitude is so thin that the heat of the sun can be felt intensely. The day temperatures in summers are just above zero degree and the night temperatures are well below -30°C. It is freezing cold in the winters, with the temperatures mostly remaining below -40°C. As it lies in the rain shadow of the Himalayas, there is little rainfall, as low as 10 cms every year.

Willows, poplars, and fruit trees such as apples, apricots and walnuts are some of the trees that grow in Ladakh.

1. The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat. 

2. It takes 4 minutes for the sun’s position to move one longitude. 

3. This means that the time is different for each degree of longitude. 

4. Based on the longitudes the time is calculated. 

5. Then two different places in our country will have different times, which cause a lot of confusion. 

6. To avoid this confusion of time from place to place 82°30’ E longitude is taken as the standard meridian of India and serves as Indian Standard Time. 

7. All people in India have to follow this time. Thus clocks show the same time.

Millions of chickens were killed (culled) in West Bengal, Orissa and Maharashtra because they were found to be infected with H5N1 virus, the causal organism of Bird Flu.

(a) Direction of magnetic field produced around a straight current-carrying conductor is given by right-hand thumb rule. If we hold a current-carrying conductor in a right hand in such a way that the stretched thumb is along the direction of current, then the curly fingers around the conductor represent the direction of magnetic field lines. 

(b) Direction of force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it, is given by Fleming’s left hand rule. Stretch the thumb, forefinger and middle finger of left hand in such a way that they are mutually perpendicular to each other. If the forefinger points to the direction of magnetic field and the middle finger points to the direction of current, then the thumb will point to the direction of motion or the force acting on the conductor.

(i) The direction of magnetic field produced around a current-carrying conductor is given by right-hand thumb rule. If the conductor carrying current is held in the right hand in such a way that the thumb points in the direction of current, then the direction of curl of fingers gives the direction of the magnetic field.
(ii) The direction of force experienced by a straight conductor carrying current placed in a magnetic field, which is perpendicular to it is determined by Fleming's left-hand rule. Hold the thumb and first two fingers of the left hand at right angles to each other with the first finger pointing in the direction of the Field and the second finger in the direction of the current, then the thumb points in the direction of the motion.
(iii) The direction of current induced in a circuit by changing magnetic flux due t a motion of a magnet is determined by Fleming'sright-hand rule. If we stretch our right hand in such a way that the thumb, forefinger and central finger remain perpendicular to each other, so that the forefinger indicates the direction of the magnetic field and the thumb in the direction of motion of conductor; then the central finger indicates the direction of induced current.

The permanent polarity is produced by the interation of lone pair & π electrons in conjugate a system of an organic molecule.

The polarity produced in the molecule by the interaction of two pi bonds or between a pi bond and lone pair of electron present on an adjacent atom.

There are two types of resonance effect: 

(1) Positive resonance effect: In this effect the transfer of electrons is away from an atom or substituent group attached to the conjugated system. The atoms or groups which shows +R effect are halogens,-OH , -OR,- NH₂ 

(2) Negative resonance effect: In this effect the transfer of electrons is towards the atom or substituent group attached to the conjugated system. The atoms or groups which shows -R effect are –COOH , -CHO , -CN 

lt is because, coal is available in Bihar/Jharkhand/ Orissa locally, whereas it has to be transported for any thermal power plant in Gujarat /Maharashtra.

small piece of dry Sodium metal is heated with a organic compound in a fusion tube for 2 -3 minutes and the red hot tube is plunged in to distilled water contained in a china dish. The contained of the china dish is boiled ,cooled and filtered. The filtrate is known as Sodium fusionextract.

By planting more trees along roadsides we reduce pollution. When we burn fossil fuels, lots of harmful gases like carbon dioxide, carbon monoxide, etc. are produced by them. These are absorbed by plants and converted into useful gases like oxygyen.

Carbon black is used as black pigment for black ink. Coke is used as a reducing agent in metallurgy. Graphite is used to make crucible and as electrodes Diamond is used in used as a abrasive, cutting tool and in jewellery.

The kinetic energy of wind is utilised to generate electricity. In this, the wind energy is used to move the turbine of windmill at high speed which generates electricity. So, the minimum speed required to move the fans of windmill is 15km/hr.

In tri silylamine N is sp₂ hybridised and pπ-dπ bonding take place while In trimethyl amine N is SP₃ hybridised and No pπ-dπ bonding.

In both the cases, the electricity generated is stored in a battery. This battery provides electricity when there is no wind in the case of a windmill and no sun in the case of a solar panel.

The material mined from earth and when heated strongly in an insufficient supply of air gives a solid fuel which is rich in carbon indicates that the material P is also very rich in carbon and hence the material has to be coal because coal is mined from earth and on incomplete combustion it gives a solid fuel.

The solid fuel Q is coke. 

R obtained from trees which signify that wood is the only tree part which when heated in insufficient supply of oxygen gives a carbon-rich compound. 

S obtained on burning wood is charcoal. 

But none of the options match with our answers. 

So correct answer is D.

A – ethyl ethanoate 

B – ethanol 

C – sodium ethanoate 

D – ethanoic acid 

Esters upon alkaline hydrolysis gives back the carboxylic acid and the alcohol. The acid is initially obtained in its salt form. The reaction is called saponification.

CH₃COOH₂CH₃ (ethyl ethanoate) \(\overset{NaOH}\longrightarrow\) CH₃COONa (sodium ethanoate) + CH₃CH₂OH (ethanol)

The salt (sodium ethanoate) is treated with dil HCl to obtain the carboxylic acid.

CH₃COONa (sodium ethanoate) + HCl → CH₃COOH (ethanoic acid) + NaCl

Ethanol is oxidized to ethanoic acid in the presence of acidified potassium dichromate. Here, the acid used for acidification is H₂SO_4.

CH₃CH₂OH (ethanol) \(\overset{Acidified\,K_2Cr_2O_7}\longrightarrow\) CH₃COOH (ethanoic acid)

These reasons were : 

1. Ranthombore was strategically very important. 

2. Ranthambore was situated quite close to Delhi. 

3. Before Alauddin, his uncle Jalaluddin Khilji had made efforts twice to occupy this fort, but he had remained unsuccessful.

On 28 January, 1303 CE, Alauddin Khilji invaded upon Chittor and on 26 August 1303 CE he occucpied it.

Option : (b) CuCl₂

Option : (a) 89°

The elements S and Cl belong to second period of the periodic table. 

Across a period effective nuclear charge increases and atomic size decreases with increase in atomic number. Therefore the energy required for the removal of electron from the valence shell (I.E.) increases in the order S < Cl.

(i) The atomic number increases as, ₁₆S < ₁₇Cl < ₁₈Ar₁.

(ii) Due to decrease in atomic size and increase in effective nuclear charge, Cl binds valence electrons strongly.

(iii) Hence ionisation enthalpy of Cl (1256 kJ mol^-1) is higher than that of S(1000 kJ mol^-1)

(iv) Ar has electronic configuration 3s²3p⁶. Since all electrons are paired and the octet is complete, it has the highest ionisation enthalpy, (1520 kJ mol^-1)

• Since halogens have eletronic configuration, ns² np⁵, they have tendency to accept one electron to complete an octet. 
• Group 17 elements have the lowest atomic radii and high effective nuclear charge. 
• Therefore halogens have high values of electronegativity. 
• The decreasing order of electronegativity is, F > Cl > Br > I 

Option : (b) Cl

Option : (b) Cl > F > Br

Option : (c) F > Br > I

Option : (d) Astatine

Option : (a) F

i. (a) 1

ii. (a) Group 2

iii. (a) Na

iv. (b) p-block

Let f : [a, b] → R be continuous on [a, b] and differentiable on (a, b), such that f(a) = f(b), where a and b are some real numbers, then there exists some c in (a, b) such that f'(c) = 0.

Given, function y = x³ + 21

Diff w.r.t. t,
dy/dx = 3x² (dx/dt)…..(i)

According to question

dx/dt = 3(dx/dt) …..(ii)

From equation (i) and (ii)

3x² = 3

⇒ x = ± 1

In equation y = x³ + 21

Putting x = 1

y = 1³ + 21

= 1 + 21 =22

Putting x = -1

y = (- 1)³ + 21 = -1 + 21 = 20

So, x = ± 1 and y = 22, 20

We have; V = x³ and ∆x = 1% of x= 0.01x

dv = \(\frac{dV}{dx}\)∆x = 3x²∆x

= 3x² × 0.01x = 0.03x³ = 0.03V

⇒ \(\frac{dV}{V}\) = 0.03

Therefore 3% is the approximate increase in volume.

(x) = x³ -x ⇒ f'(x) = 3x² – 1
⇒ f'(x) = 0 ⇒ 3x² – 1 = 0 ⇒ x = ± \(\frac{1}{\sqrt3}\)
This turning point divides the domain into the intervals (-∞, \(\frac{1}{\sqrt3}\)); (-\(\frac{1}{\sqrt3}\), \(\frac{1}{\sqrt3}\)); (\(\frac{1}{\sqrt3}\), ∞).

1. Interval (-1, 0), f'(x) changes sign. So not monotonic.
2. Interval (-1, -1/2), f'(x) > 0 strictly monotonic.
3. lnterval (-1, 1) not monotonic
