Learning a new skill is quite challenging. I vividly remember the challenges I had to face to learn to ride bicycle. My father could not afford me children’s bicycle, which has safety wheels on either side of the bicycle to keep you from falling. So I had to learn bicycling on my father’s bicycle. It was far to bigger than me; I had real difficulty controlling it. Since my height was very short, I could not mount the seat meant for riders, I just hung on it and ran along as it moved. I fell hundreds of times, injuring myself; but I never gave up.

Initially my cousins helped me balance it. thus slowly, gradually I learnt to maintain balance. Finally I succeeded in riding it. I was greatly thrilled to have ridden it without falling.

I remember that I faced a lot of difficulties in learning swimming. The Yamuna River flows near to my village and I had the fear of swimming. But the children of my age often went there to enjoy and play in the water. I too wanted to enjoy but was always taken aback due to my deep seated fears. However, one day I decided to go in the river in the presence of my uncle. He held me with his hands and I gave my first attempt in shallow waters. Slowly I started to move my hands and legs and gradually began to float in water. I repeated it again and again and within some days of rigorous practice, I gained a lot of confidence. Eventually, I overcame my fears and learned to swim confidently.

• The poet talks of the need for silence and quiet introspection and the value of calmness and quietude. He also speaks about creating a sense of shared understanding between men. By this there will be an end to all forms of conflicts. Keeping quiet will help us introspect, reflect and experience silence and peace. This will in turn assist us in finding solutions to our problems
• During these few moments of  quietness and introspection all people would be unified and in harmony with nature and each other. This oneness and togetherness is desirable and essential for the Earth's survival and of human beings as well. When the people are silent for a moment, they remember their life's meaning. Even like all natural things experience a rebirth with the transition of time, so keeping quiet  is a rebirth of the human soul. This gives our lives a new meaning.
• The poet wishes us to be still, to cease our confused and hurried movements and try to be calm for a change instead of being restless all the time. The poet suggests that there is life in nature under apparent stillness via the example where The Earth teaches us in what way  new life evolves from the dead remains. It gives us lessons about resurrecting and sustaining life.

The standard form of a quadratic equation is ax²+bx+c=0, where a,b and c are real numbers and a≠0.
‘a’ is the coefficient of x². It is called the quadratic coefficient. ‘b’ is the coefficient of x. It is called the linear coefficient. ‘c’ is the constant term.

The cone bearing plants are called Conifers.

Karyokinesis is defined as the division of the nucleus during the M phase of the cell cycle. It is the first step in M phase. In this process, the DNA condenses and the chromosomal material divides equally into two halves. This process occurs in four steps-peophase, metaphase, anaphase and telophase.

A convex lens is a lens with an outward curve. Unlike the concave lens, the thickness at the centre of a convex lens is more than the thickness at the edges of the lens. Convex lenses are converging lenses. They have the ability to converge a parallel beam of light into a point. This point is called the focal point of the convex lens and the distance from the optical centre to the focal point is called the focal length. The focal point is on the opposite side of the lens from which the light rays originate.

Mesopotamia important to Europeans because:

• Mesopotamia has good fertile land and it is considered to be ancestors' land.

• It is very important to Europeans because many inventions and developments started from here only.

• Mesopotamia is important to Europeans because it has Tigris and Euphrates rivers that's why Mesopotamia land is a fertile crescent and the soil is also nutrient-rich.

• This is one of the important reason Mesopotamia is so valuable to Europeans.

In the given figure, O is the centre of a circle and ∠BOD =150°. Find the values of x and y.

Answer:

It is given that O is the centre of a circle and ∠BOD =150^o

We know that

Reflex ∠BOD = (360^o – ∠BOD)

By substituting the values

Reflex ∠BOD = (360^o – 150^o)

By subtraction

Reflex ∠BOD = 210^o

Consider x = ½ (reflex ∠BOD)

By substituting the value

x = 210/2

So we get

x = 105^o

We know that

x + y = 180^o

By substituting the values

105^o + y = 180^o

On further calculation

y = 180^o – 105^o

By subtraction

y = 75^o

Therefore, the value of x is 105^o and y is 75^o.

Rice

1. It is a kharif crop.
2. It requires high temperature and high humidity with annual rainfall above 100 cm.
3. India is the second largest producer of rice in the world after China.
4. It is grown in the plains of north and north-eastern India, coastal areas and the deltaic regions.

The rate of groundwater utilization is very high in the river basins of north west India and parts of south India, where the rain water percolates down easily through the soft soils and recharge underground water table. It is also easy to construct wells and tube wells here. Surface water is more utilized in the crystalline rocks of south India.

संविधान का कार्य निम्नलिखित है : 

(i) संविधान का पहला काम यह है कि वह बुनियादी नियमों का एक ऐसा समूह
उपलब्ध् कराये जिससे समाज के सदस्यों में एक न्यूनतम समन्वय और विश्वास
बना रहे।

(ii) संविधान का दूसरा काम यह स्पष्ट करना है कि समाज में निर्णय लेने की शक्ति किसके पास होगी। संविधन यह भी तय करता है कि सरकार कैसे निर्मित होगी।

(iii) संविधान का तीसरा काम यह है कि वह सरकार द्वारा अपने नागरिकों पर लागू किये जाने वाले कानूनों पर कुछ सीमाएँ लगाए। ये सीमाएँ इस रूप में मौलिक होती हैं कि सरकार कभी उसका उल्लंघन नहीं कर सकती।

(iv) संविधान का चौथा काम यह है कि वह सरकार को ऐसी क्षमता प्रदान करे जिससे वह जनता की आकांक्षाओं को पूरा कर सके और एक न्यायपूर्ण समाज की स्थापना के लिए उचित परिस्थितियों का निर्माण कर सके।
