CIRCULAR MOTION

...........................

Given:

A body is projected vertically upwards with a velocity of 40 m/s

So, Initial velocity of the body ( u ) = 40 m/s

Since, the body COMES to rest after REACHING maximum height

Final velocity of the body ( v ) = 0 m/s

The stone is thown upwards so g is considered as negative

Acceleration due to GRAVITY acting on the body ( g ) = - 10 m/s²

Let the maximum height reached by the body be 'H' m

Using third equation of motion

⇒ v² - u² = 2gh

⇒ 0² - 40² = 2( - 10 )( h )

⇒ 0 - 1600 = - 20h

⇒ 20h = 1600

⇒ h = 1600 / 20

⇒ h = 80

Therefore the maximum height reached by the body is 80 m ( A )

Answer:

0.671 A

Explanation:

There is no current division occurring in a SERIES circuit. Current flow through the component is the same.

RESISTANCES are connected in series. Hence, the sum of the resistances will give the value of R. R = 0.2 + 0.3 + 0.4 + 0.5 + 12 = 13.4 Ω

Potential difference, V = 9 V

I = V = 9V = 0.671 A

R 13.4Ω

∴ the current that WOULD flow through the 12 Ω resistor will be 0.671 A.

Answer:

Given:

Initial time PERIOD = T

Spring is cut into 2 pieces and again suspended from one half

To find:

New time period

Calculation:

Let the initial Spring CONSTANT be K and FINAL spring constant be k2 . Since it is cut, we can say that :

Initial time period = T

Putting new constant for spring :

So final answer :

Answer:

The answer to this question is

(a) 48 ohm

(b) 2 ohm

Explanation:

The highest RESISTANCE is =

R = R1 + R2 + R3 + R4

R = 4 + 8 + 12 + 24

R = 48 ohm

The longest Resistance is =

1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4

1/R = 1/4 + 1/8 + 1/12 + 1/24

1/R = 1/2

R = 2 ohm.

Therefore The LOWEST resistance = 2 ohm.

ANSWER:

No source of energy can be calledpollution-free, because, the use of any source of energy disturbs the environment in one way or the other. A source of energy likea solar cell is POLLUTION free in ACTUAL operation but the assembly of the device MIGHT have caused some damage to the environment.

Answer:

Prokaryotes are simple, SMALL cells, whereas eukaryotic cells are complex, large STRUCTURED and are present in trillions which can be single celled or multicellular. Prokaryotic cells do not have a well-defined nucleus but DNA molecule is located in the cell, termed as nucleoid, whereas eukaryotic cells have a well-defined nucleus, where genetic material is stored. Based on the structure and functions, cells are broadly classified as Prokaryotic cell and Eukaryotic cell

Prokaryotic Cells are the most primitive kind of cells and lack few features as compared to the eukaryotic cell. Eukaryotic cells have evolved from prokaryotic cells only but contain different types of organelles like Endoplasmic reticulum, Golgi body, Mitochondria etc, which are specific in their functions. But features like

growth, response, and most importantly giving birth to the young ones are the commonly SHARED by all living organisms.

EXPLANATION:

जागरण संवाददाता, आगरा : 'यदि आपका मन सच्चा है तो आपका चरित्र सुंदर होगा। यदि चरित्र में सुंदरता है तो घर में सामंजस्य होगा। घर में सामंजस्य है तो देश में व्यवस्था स्थापित होगी। यह एक सराहनीय प्रयास होगा।' कन्फ्यूशियस के उक्त विचार वर्तमान में बिल्कुल सटीक बैठ रहे हैं। जिस प्रकार मनुष्य के हृदय पर प्रकृति के सौंदर्य का स्थायी प्रभाव पड़ता है। उसी प्रकार शिक्षा के क्षेत्र में भी सौंदर्य बोध की अहम भूमिका है। इसके अभाव में वह निष्प्राण हो जाती है। हमारे पास एक भौतिक शरीर, मन और बुद्धि है। भावनाएं हैं और हमारा एक आध्यात्मिक पक्ष भी है और यही हमें सौंदर्य का बोध कराता है। भारतीय संस्कृति सदैव ही भौतिकता के स्थान आध्यात्मिकता को प्राथमिकता देती आई है। ऐसा माना जाता है भौतिक शरीर क्षण भंगुर तथा आत्मा अमर है।

अत: आत्म विकास के लिए जीवन में सौंदर्य बोध को अपनाना आवश्यक हो जाता है। शिक्षण संस्थाओं में नवाचार की अवधारणा का मुख्य उद्देश्य छात्र-छात्राओं में सौंदर्य बोध से संबंधित भावनाओं का विकास करना है। उनके मन में समाज एवं देश के प्रति उत्तरदायित्व तथा प्रकृति के प्रति प्रेम भावना विकसित करना भी है। शिक्षा में यदि सौंदर्य आ जाता है तो बच्चों का दृष्टिकोण ही बदल जाता है। जिससे उनमें नैतिक गुणों का विकास होता है और वो विश्व बंधुत्व के भाव से युक्त हो जाते हैं। उनके मन में सांप्रदायिक सद्भाव की भावना जाग्रत हो जाती है। सौंदर्य बोध के भाव जाग्रत होने के कारण ही विद्यार्थी के मन में प्रेम, करुणा, उत्साह आदि का विकास होता है। परिणामस्वरूप वह परायों को भी अपना बना सकता है। मनुष्य को मनुष्य से जोड़ सकता है। अशांत मन को शांत कर सकता है। मन की पीड़ा को मिटाकर जीवन रस की वर्षा कर सकता है। सौंदर्य बोध के ही कारण वह ईश्वर प्रेम, राष्ट्रप्रेम व विश्वप्रेम आदि के द्वारा सारे विश्व को एक कर सकता है। वर्तमान शिक्षा प्रणाली का लक्ष्य छात्रों के व्यक्तिव का सर्वांगीण विकास करना, किताबी ज्ञान के साथ-साथ छात्र-छात्राओं के व्यक्तिव का सकारात्मक विकास करना है। इससे समाज में बदलाव की लहर आ सकती है। आज पारंपरिक तरीकों के अलावा ऐसे नए तरीके शिक्षण में प्रयोग किए जा रहे हैं जो विभिन्न क्षेत्रों में छात्र-छात्राओं की प्रतिभा को उभारने में सक्षम है। जिस तरह तकनीक के क्षेत्र में हर दिन बदलाव आ रहा है, उसे देखते हुए ऐसी शिक्षा उन्हें देना जरूरी भी है। आज शिक्षण संस्थाओं में ललित कलाओं के अंतर्गत संगीत, नृत्य, चित्रकला, नाट्य कला आदि रचनात्मक कौशलों को भी शामिल किया गया है। जिससे छात्रों को रुचि अनुसार सीखने का अवसर प्राप्त होता है। जो उनके सूक्ष्म सौंदर्य बोध को समृद्ध करते हैं।

Answer:

An optical fiber An optical fiber is a thin fiber of glass or plastic that can carry light from one end to the other. The study of optical fibers is called fiber optics, which is part of applied science and engineering

Light travels down a fiber optic cable by bouncing off the walls of the cable repeatedly. Each light particle (photon) bounces down the pipe with continued internal mirror-like REFLECTION. The light beam travels down the core of the cable

Optical fiber is used as a medium for telecommunication and COMPUTER networking because it is flexible and can be bundled as CABLES. It is especially advantageous for long-distance communications, because infrared light propagates through the fiber with MUCH lower attenuation compared to ELECTRICAL cables.

EXPLANATION:

For the string of mass 'm',

P−mg−F=ma

For the body of mass M,

F−Mg=Ma

Adding, we have:

p−mg−Mg=Ma+ma

⟹a= P - G

M+m

Force EXERTED by string on the body F=M(g+a)

Substituting the value of a in it, we have:

F=M(g+ PM - g)

M+m

⟹F = PM

M+m

GIVEN that,

u=10m/s, V=?m/s, a=2m/s^2, t=2 seconds

We have,a= v-u/t

2=v-10/2

2×2=v-10

4+10=v

v=14m/s

Hence,its FINAL SPEED or VELOCITY is 14m/s.
