यह प्रसंग पढ़ें, मिहिर और मोरपाल के जीवन अनुभवों के आधार पर टिप्पणी लिखें।

‘जिस स्कल में बिताए समय को मैं अपने बचपन का सबसे खराब समय समझ करता था, शायद वही मोरपाल के लिए उसके जीवन का सबसे अच्छा समय होता था।’
उत्तर:
समाज के दो पहलू
मिहिर एवं मोरपाल दोस्त थे। दोस्ती इतनी घनी थी कि खाने की चीज़ भी आपस में बाँट लेते थे। मोरपाल गरीब घराने का लड़का है। उसके माँ-बाप खेत-मजूरी करते थे। घर में उसे कमर तोड़ मेहनत है। फिर भी वह रोज़ स्कूल आना पसंद करता है। पंद्रह किलोमीटर दूर किसी गाँव से रोज़ साइकिल चलाता स्कूल आता था। रोज़ छाछ का डिब्बा लेकर आता था। स्कूल आकर लेखक (मिहिर) का राजमा-चावल बडी चाव से खाता था। क्योंकि उसने पहले कभी यह देखा ही नहीं। स्कूल के प्रति उसका लगाव कुछ खास है इतना कि बिना नागा रोज़ स्कूल आता था। रविवार की छुट्टी का दिन उसके लिए हफ़्ते का सबसे बुरा दिन था। किसी शादी में भी स्कूल के नीली-खाकी यूनीफॉर्म पहनते दिखाई पड़ता था। बेचारे के पास जो कमीज़पैंट का एक ही जोड़ा था, वह नीली-खाकी यूनीफॉर्म था। मोरपाल का स्कूल आठवीं के बाद छूट जाता है। वह आज भी अपने पिता की तरह वहीं खेती-मजूरी करता है।

मिहिर पांडेय धनी परिवार का है। घर मे सारी सुविधाएँ हैं। वह स्कूल जाने से रोया करता था। रोज़ नए बहाने बनाता था। स्कूल से इतना नफ़रत करता था कि अगर स्कूल के रास्ते में पानी भर जाने के कारण स्कूल की छुट्टी हो जाए तो घर में वह नाचता रहता था। उसे स्कूल की नीली-खाकी यूनीफॉर्म से घृणा थी। उसे पहनना हमेशा टाल देता था। स्कूल में बिताए समय को वह अपने बचपन का सबसे खराब समझा जाता था। अपने राजमा-चावल के बदले मोरपाल का छाछ का डिब्बा अपना लेता था।

समाज के दो विभिन्न पहलुओं को मिहिर और मोरपाल के माध्यम से हमारे सामने पेश किया है। मोरपाल के लिए घर में कोई सुविधा नहीं है, फिर भी वह पढ़ना चाहता है। जबकि मिहिर के लिए सुविधा होते हुए भी स्कूल जाना पसंद नहीं करता। स्कूल एवं यनीफॉर्म से गहरा प्यार रखते हुए भी मोरपाल को आठवीं से स्कूल छोडना पडता है और वह पिताजी की तरह खेतीमजूरी करने को विवश होता है। मगर विशेष रुचि न रखते हुए भी मिहिर ऊँचे पद पर पहूँचता है। यहाँ सामाजिक असमता का तस्वीर खींच लिया है।

उत्तर:
20 मई 2019
आज कैसा दिन रहा ! सालों का मेरा सपना आज पूरा हुआ। मेरी खुशी का ठिकाना नहीं। स्कूल में मेरी भर्ती हुई। दोस्त रणविजय के साथ मैं भी स्कूल जा रहा हूँ। सारे लोगों ने मुझे चोर बुलाया था। उस दिन मैं कितना रोया था। मुझे लूसी मैडम से मिलने था। इसलिए सीधे दिल्ली गया था। रास्ते में कितनी मुश्किलें सहना पड़ा था। न खाना, न रहन-सहन। संयोग से हुई मुलाकात की वजह से दोस्त रणविजय एवं रिश्तेदारों को मिला। इसलिए आज स्कूल जाने का सौभाग्य प्राप्त हुआ है। आगे मन में यही वादा है खूब पढूँगा और मंज़िल तक पहुँच जाऊँगा। सीधे डॉ. कलाम से मिलूँगा और खूब बातें करेगा। गाँववालों की मदद करूँगा। काश मैं कलाम बन जाएँ.

Answer:

1. Mechanical energy
2. Heat energy
3. Electrical energy
4. Chemical energy
5. Light energy
6. Nuclear energy

There are two type of Mechanical energy Kinetic energy and potential energy

Kinetic Energy

Pulling the toy car backwards a little and allow it to hit the plastic ball

Question 19.
What happened to the ball when the moving car hit it?
Answer:
Ball moves forward

10 to the 9th power Question 20.
How did the car get the energy to move the ball forward?
Answer:
The energy is obtained from the motion of toy car
Conclusion:

• Moving objects possess energy
• The energy possessed by a body by virtue of its motion is the Kinetic energy

Experiment:
Let’s do another activity. Allow a powder tin to slide down a polished, inclined plane as shown in the figure and let it hit a toy car. Try to measure the displacement of the toy car. Repeat the experiment by increasing the height of the inclined plane and filling the tin with sand.

Observation:

• The displacement of the toy car is greater When it is hit by the powder filled with sand
• Also the displacement is greater when it is dropped from a greater height

Conclusion: Kinetic energy depends on mass (m) and velocity (v)
Derivation of the equation for calculating K.E
Work W = Fs
As per II law of motion
F = ma
∴ W = mas
According to third equation of motion
v² = u² + 2as = 0 + 2as (u = 0) = 2as
∴ as = \(\frac{v^{2}}{2}\)
W = mas , if we put \(\frac{v^{2}}{2}\) instead of as

Work is equal to the magnitude of kinetic energy
i.e, Kinetic energy K = \(\frac { 1 }{ 2 }\) mv2,
M – mass, V – Velocity
When a body of mass m moves with a velocity v, its kinetic energy will be K = \(\frac { 1 }{ 2 }\) mv2

Question 21.
A man having a mass of 70kg is riding a scooter of mass 80kg. What is the total kinetic energy if the velocity of the scooter is 10m/s?
Answer:
m = 70kg + 80kg = 150kg
v = 10m/s

Question 22.
A car of mass 1500 kg is moving at a velocity of 20m/s. What is its kinetic energy?
Answer:
m = 1500 kg
v = 20m/s
K = \(\frac { 1 }{ 2 }\) mv²
= 1/2 × 1500 × 20²
= 300000J = 300kJ

Question 23.
A boy of mass 50kg is riding a bicycle with a speed 2m/s. The bicycle has a mass of 10kg. Calculate the total kinetic energy?
Answer:
m = 50kg + 10kg = 60kg
v = 2m/s
K = \(\frac { 1 }{ 2 }\) mv²
1/2 × 60 × 2² = 120J

Potential Energy

When we lift a body in perpendicular direction, the work is said to be done against gravitational force. According to figure, maximum work is done when it reaches at a height fb from the group, That means as the height increases work done also increases.

• The energy received by the body is equal to the work done on it.
• The body attains more energy when the height from the ground level increase

The energy possessed by a body due to its position is the potential energy.
ie, Potential energy
U = mgh
m – mass, g – acceleration due to gravity
h = height from the ground

Question 24.
Identify more situation in which potential energy is acquired by virtue of position
Answer:

• Coconut in a coconut tree
• Water stores in huge reservoirs
• Objects placed above the buildings,

Inference:
Height increases, potential energy increases

Question 25.
Write down situations in which potential energy varies.
Answer:

• Falling of a coconut from a coconut tree
• Pumping water to a tank at a height
• Climbing a ladder

Question 26.
Calculate the potential energy of a body of mass 1 kg at a height of 6m from the ground?
Answer:
Mass m = 1 kg, Acceleration due to gravity
g = 10m/s²
h = 6 m,
U = mgh = 1 × 10 × 6 = 60J

Question 27.
A bird of mass 0.5 kg is flying at the same speed at the same height of 5m. In this state, if its Kinetic energy and potential energy are equal.
a) What is the potential energy of the bird?
b) What is the velocity of the bird?
Answer:
a) m = 0.5kg
g = 10m/s²
h = 5m
u = mgh
= 0.5 × 10 × 5 = 25J
b) Kinetic energy K = 25J (∴U = K)

Question 28.
Write other examples for getting potential energy due to strain
Answer:

• A Stretched bow
• An elongated rubber band
• Compressed spring
• Compressed spring in a toy car

Conclusion: The factor which gives potential energy are position and strain

c) Total energy = PE + KE
= 600J + 0 = 600J

Question 35.
While falling, when the flower pot is at a height of 2m from the ground, what will be its kinetic energy?
Answer:
K = \(\frac { 1 }{ 2 }\) mv²
u = 0, g = 10m/s² ,
s = 4 – 2 = 2m
v² = u2² + 2as
=0 + 2 × 10 × 2 = 40
K = 1/2 × 15 × 40
= 300J

Question 36.
What is the potential energy when it is at a height of 2m from the ground? What is the total energy now?
Answer:
Potential energy at 2m height
U = mgh = 15 × 10 × 2 = 300J
∴ Total energy = 300 + 300 = 600J

Question 37.
What is the kinetic energy of the flower pot just before it touches the ground?
Answer:
K = \(\frac { 1 }{ 2 }\) mv²
