सममान रेखा मानचित्र क्या है? एक क्षेपक को किस प्रकार कार्यान्वित किया जाता है?

Answer»

सममान रेखा मानचित्र- काल्पनिक रेखाएँ जो समान मान के स्थानों को जोड़ती हैं, ‘सममान रेखाएँ’ कहलाती हैं। इन रेखाओं द्वारा भौगोलिक सत्य को मानचित्र पर दिखाना ‘सममान रेखा मानचित्र’ कहलाता है।

क्षेपक का कार्यान्वयन– क्षेपक का उपयोग दो स्टेशनों के प्रेक्षित मानों के बीच मध्यमान को प्राप्त करने के लिए किया जाता है, जैसे—आगरा और मेरठ का तापमान या दो बिन्दुओं की ऊँचाइयाँ।

समान मानों के स्थानों को जोड़ने वाली सममान रेखाओं का चित्रण ‘क्षेपक’ कहलाता है। क्षेपक के कार्यान्वयन करने के लिए निम्न बातों की पालना करनी पड़ती है

⦁    मानचित्र पर न्यूनतम और अधिकतम मान को निश्चित करना।
⦁    मान की परास की गणना, जैसे-परास = अधिकतम मान – न्यूनतम मान।
⦁    श्रेणी के आधार पर 5, 10, 15 आदि में अन्तराल निश्चित करना।

A cylindrical pillar is 50 cm in diameter and 3.5 m in height. Find the cost of painting the curved surface of the pillar at the rate of Rs.12.50 per m2.  [ Assume π = 22/7 ]

Answer»

Height (h) cylindrical pillar = 3.5 m

Radius (r) of the circular end of pillar 

= 50/2 cm =25cm = 0.25m

CSA of pillar = 2πrh

= (2 x 22/7 x 0.25 x 3.5)m2

= (44 x 0.125)m2 = 5.5m2

Cost of painting 1 m2 area = Rs 12.50

Cost of painting 5.5 m2 area = Rs (5.5 × 12.50) = Rs 68.75

Therefore, the cost of painting the CSA of the pillar is Rs 68.75.

14.

The inner diameter of a circular well is 3.5 m. It is 10 m deep. Find(i) Its inner curved surface area,(ii) The cost of plastering this curved surface at the rate of Rs 40 per m2.[ Assume π = 22/7 ]

Answer»

Inner radius (r) of circular well = (3.5/2)m = 1.75m

Depth (h) of circular well = 10 m

Inner curved surface area = 2πrh

= (2 x 22/7 x 1.75 x 10) m2

= (44 x 0.25 x 10) m2

= 110 m2

Therefore, the inner curved surface area of the circular well is 110 m2.

Cost of plastering 1 m2 area = Rs 40

Cost of plastering 100 m2 area = Rs (110 × 40) = Rs 4400

Therefore, the cost of plastering the CSA of this well is Rs 4400.

15.

The inner diameter of a cylindrical wooden pipe is 24 cm and its outer diameter is 28 cm. The length of the pipe is 35 cm. Find the mass of the pipe, if 1 cm3 of wood has a mass of 0.6 gm.

Answer»

Let r and R be the inner and outer radii of cylindrical pipe.

Inner radius of a cylindrical pipe (r) = \(\frac{24}{2}\) = 12 cm 

Outer radius of a cylindrical pipe (R) = \(\frac{24}{2}\) = 14 cm 

Height of pipe (h) = length of pipe = 35 cm 

Mass of pipe = volume x density = π(R2 – r2)h 

= \(\frac{22}{7}\)(142 – 122)35 

= 5720 

Mass of pipe is 5720 cm3 

Mass of 1 cm3 wood = 0.6 gm

Therefore, mass of 5720 cm3 wood = 5720 x 0.6

= 3432 gm 

= 3.432 kg

16.

In a hot water heating system, there is a cylindrical pipe of length 28 m and diameter 5 cm. Find the total radiating surface in the system.

Answer»

Given that 

Height of cylinder = length of cylindrical pipe = 28 m.

Radius (r) of circular end of pipe = 5/2 cm = 2.5 cm = 0.025 m

Curved surface area of cylindrical pipe = 2πrh

= 2 x 3.14 x 0.025 x 28 = 4.4 cm

 The area of radiation surface of the system is 4.4 m2 or 44000 cm2

When a tree is shaken, its fruits and leaves fall down, why?

Answer»

When a tree is shaken, its fruits and leaves fall down because their state of rest is disturbed and thus they separate from the tree.

18.

Why fruits fall down from a tree, when its branches are shaken?

Answer»

Before shaking the branches, fruits are at rest. When branches are  shaken, they come in to motion, while the fruits remain at rest due to inertia of rest. As a result of this fruits get detached from the branches and fall down.

19.

When a tree is shaken, its fruits and leaves fall down: Why ?

Answer»

When a tree is shaken, the tree moves to and fro while the fruits and leaves remain in their state of rest on account of their inertia and thus fruits and leaves separate from the tree and fall from the tree.

Attempt a comparative study of American War of Independence and Indian Independence Movement.

Answer»

Comparison between American War of Independence and Indian Independence Movement: 

A. Similarities 

1. Both the Americans and the Indians gained their freedom by challenging the British Empire with the use of alternating tactics and policies. 

2. Both wanted to be free because they were being coerced and restricted. 

3. The British Empire had a major influence on the development of Indian and American human societies. 

4. Indians boycotted British products in hopes of helping the Indian economy. Similarly, the Americans boycotted British tea and other products to get the attention of the British rule.

B. Differences 

1. Indians chose a peaceful way of gaining independence while Americans chose a violent way. The respective paths they chose were greatly influenced by their culture and the time periods they were in. 

2. Their leaders and strategies were extremely different. 

3. The American colony was actually a colony where the descendants of British people rebelled against Britain, whereas in India the rebellion was by the natives.

4. The United States relied on the assistance of France, while India had no externally. 

5. The British policy in America was to displace the native population and settle the territory as English territory, while India was more densely populated and the British policy centered on economic exploitation rather than full displacement and incorporation. 

6. The American Revolution took place just before the Industrial Revolution (when colonial arms were as good as British arms). The Indian Independence Movement took place well into the Industrial Revolution (when home country arms were potentially much better).

Give two points of difference between :  Instrumental Music   Vocal Music (1) ......(2) ......

Answer»
  Instrumental Music   Vocal Music
 (1) Instruments are used. The voice (vocal cords) are used.
 (2) Some part of the body is used as a medium to produce the sound, but the final sound is produced by the instrument. Some parts of the body aid the production of sound (e.g., lungs, vocal tract, etc.), but the final sound emerges through the mouth.
 (3) The output of the instrument is more or less of the same type, although the way the musician plays can give it an individualistic flavour. Individual voices vary from the very low bass to the very high tenor. Hence the output varies and is very individualistic.
 (4) An instrument can hardly be expected to sound like a voice (although some musicians try). The voice can be used to imithte the sound of an instrument.

‘Music is the medicine of the mind’. Narrate an experience that leads to the above conclusion. Write it in your own words

Answer»

Music is the medicine of the mind Music is good therapy. It is particularly effective because it registers on multiple sites of the brain. This means that even if the brain is very badly affected by a stroke or illness, there are s^till parts of the brain that recognise music.

I remember how upset all of us were when Grandfather suffered a stroke. The left side of his body and almost all of his face were affected. The once great and active Grandpa now lay still on the bed and had to be fed through a tube going down his nostrils. Little Rani could not stop weeping.

Grandfather had once presented me with a mobile phone. He knew my love for music and had told me I could download my favourite songs and create a playlist and listen to them whenever I wanted to.

I would sit by Grandfather’s bed whenever I was at home and had finished my studies and play the songs and listen to them.

One evening, to my surprise, I saw a shadow of a smile beginning to appear on Grandpa’s face. At first I couldn’t believe it. Then it became more definite and prominent. Grandpa was actually smiling!

I called Mom and Dad and Rani and everyone to see. Yes, Grandpa was indeed smiling. The music had reached out to him and had drawn out a response from him. 

That was one of the happiest moments during his illness.
