(i) Eating disorders: Adolescents obsession with self-living in fantasy world and peer comparisons lead to certain conditions where they become obsessed with their own bodies.

(ii) Anorexia nervosa: It is an eating disorder that involves relentless pursuit of thinness through starvation. It is quite common to see adolescents eliminate certain foods from their diets or to eat slimming foods only. The media also projects thinness, as the most desirable image and copying such fashionable image of thinness leads to anorexia nervousa.

The blumic goes on an eating binge, then purges by self-induced vomiting or using a laxative at times alternating it with fasting. Anorexia neruousa and bulimia are primarily female disorders more common in urban families.

........... with her friend. 

. Suddenly they heard some animal screaming. It was so sudden that they jumped with fright. They looked at each other. They decided to climb the nearest tree to see what was the matter. They saw that at a distance there was an animal. A hunter was aiming at it.

           It was screaming for help. The two friends thought quickly. They jumped down from the branches and ran in the direction of the hunter. They threw sticks and fruits from the nearby trees in the direction of the hunter. Then they ran past him. He got distracted and lost his aim. In the meantime the animal got a chance to escape. He quickly jumped and ran away into the forest.

          The hunter was furious. He wanted to catch the two friends and punish them. But the friends were too quick for him. They threw their water bottles on him. Before he could recover from the shock the friends vanished.

Morphology is the branch of biological science that deals with the study of form, size, colour, structure and relative position of various parts of organisms.

Importance of morphology-

1. Knowledge of morphology is essential for recognition or identification of plants.
2. It gives information about the range of variations found in species.
3. Deficiency and toxicity symptoms are morphological changes that occur in response to shortage or excess of minerals.

My childhood summary deals with the famous biography “Wings of Fire” of the celebrated Indian APJ Abdul Kalam. My Childhood refers to a section in this book. This section or chapter talks about the early days’ of Kalam. Furthermore, the chapter gives us an idea of how the childhood of Abdul Kalam prepared him to become a successful scientist and president in the future. Much has to do with his upbringing which Kalam discusses in this section from “Wings of Fire”. Moreover, Kalam tells us about his parents and siblings here. He also mentions the important role of his friends in his life. In short, one can say, that in My Childhood, Kalam mentions everything that had an impact on his life. These things shaped him into the successful man he became in the future.

In his last French class though M. Hamel was emotional he fully involved himself in the teaching-learning process. He heard every lesson to the last sitting motionless in the chair. When the church bell struck twelve he stood up pale and wrote ‘Vive La France’ and with a gesture, he communicated that the school is dismissed.

Angular velocity= w= 60rev/min
1 revolution= 2pi radian
one minute = 60 sec
w= 60*2pi/60
w= 2pi radian/sec
mass= 18g = 0.018 kg
distance =r= 8 cm = 0.08 m
f= mv^2/r
v=rw v^2=r^2w^2
f= mr^2w^2/r
r in division will be removed by removing square

F= mrw^2
f= 0.018*0.08*(2pi)^2
square of 2 is 4
nd pi^2= 9.87 as per your question
so:
0.018*0.08*4*9.87
= 0.05685
= 0.057

- Manufacturing industries assist in modernising agriculture and it reduce the heavy dependence on agricultural productivity.

- It generates more employment opportunities and removes unemployment and poverty level in our nation.

- It provides balanced regional growth in all areas of an economy. Export of manufactured goods expands trade and commerce, and brings in much needed foreign exchange.

- Countries that transform their raw materials into a wide variety of furnished goods of higher value are prosperous.

- Industry sector contributes 27 % of GDP out of it manufacturing accounts for 17 %.

- The other ways of measuring the development of economy is to measure per capita income, total income of the country, the extent of import/export, the gdp (gross domestic produce) and the fiscal deficit.

(i) (cosec θ – cot θ)² = (1-cos θ)/(1+cos θ)

To prove this, first take the Left-Hand side (L.H.S) of the given equation, to prove the Right Hand Side (R.H.S)

L.H.S. = (cosec θ – cot θ)²

The above equation is in the form of (a-b)², and expand it

Since (a-b)² = a² + b² – 2ab

Here a = cosec θ and b = cot θ

= (cosec²θ + cot²θ – 2cosec θ cot θ)

Now, apply the corresponding inverse functions and equivalent ratios to simplify

= (1/sin²θ + cos²θ/sin²θ – 2cos θ/sin²θ)

= (1 + cos²θ – 2cos θ)/(1 – cos²θ)

= (1-cos θ)²/(1 – cosθ)(1+cos θ)

= (1-cos θ)/(1+cos θ) = R.H.S.

Therefore, (cosec θ – cot θ)² = (1-cos θ)/(1+cos θ)

Hence proved.

(ii)  (cos A/(1+sin A)) + ((1+sin A)/cos A) = 2 sec A

Now, take the L.H.S of the given equation.

L.H.S. = (cos A/(1+sin A)) + ((1+sin A)/cos A)

            = [cos²A + (1+sin A)²]/(1+sin A)cos A

            = (cos²A + sin²A + 1 + 2sin A)/(1+sin A) cos A

Since cos²A + sin²A = 1, we can write it as

            = (1 + 1 + 2sin A)/(1+sin A) cos A

            = (2+ 2sin A)/(1+sin A)cos A

            = 2(1+sin A)/(1+sin A)cos A

            = 2/cos A = 2 sec A = R.H.S.

L.H.S. = R.H.S.

(cos A/(1+sin A)) + ((1+sin A)/cos A) = 2 sec A

Hence proved.

Sanskrit Letter Writing - आपको परीक्षा में इस तरह से प्रश्न पूछा जाता है:

1. स्वपितरं प्रति लिखितम् अधः पत्रं मञ्जूषाप्रदत्तशब्दैः पूरयित्वा पुनः लिखित -
(1/2 X 10 = 5)
इसका अर्थ हुआ कि आपको अपने पिता को लिखे गए निम्नलिखित पत्र को आपको मञ्जूषा की सहायता से पूरा करना है और अपनी उत्तर पुस्तिका पर दोबारा लिखना है।

(इस पत्र में आपको हर एक रिक्त स्थान के लिए आधा अंक निर्धारित होता है अर्थात पूरे प्रश्न के पांच अंक होते हैं और यदि आप इस प्रश्न में शब्दों को सही जगह रख दें तो यहाँ आपके अंक कटने की सम्भावना बिलकुल नहीं होती क्योंकि आपको केवल मञ्जूषा से जैसे के तैसे शब्दों को लिखना होता है।)
(आपको इस तरह से पत्र दिया होता है )

Length of the boundary of the semicircular park = 90 m
⇒ πr + 2r = 90
⇒ r(22/7 + 2) = 90
⇒ r = (90*7)/36
⇒ r = 17.5 m
Area of the semicircular park = 1/2πr²
= 1/2*22/7*17.5*17.5
= 481.25 sq m
