The habit of reading

*THE HABIT OF READING*

“Reading makes a full man” – Francis Bacon
If walking exercises the muscles of the whole body than the same can be said for the habit of reading for the mind - it develops all the faculties of the mind. Reading can be initiated at an early age and gets better as students move up in higher grades and beyond. Studies show that cultivating lifelong reading habits is essential to long-term success. Here are some of the benefits of reading especially for young students :

*Develops Mental Capacity* - Reading develops the mind’s ability to think larger. It rather enables a student to think on subjects and people that the reader thought never existed.

*Enriches Vocabulary -* The new words and phrases one learns during the course of reading enriches the student’s language which can improve his/her comprehension and expression in all the subjects.

*Expands the horizons of the mind* - The easiest way to understand the various cultures and practices that exist in this world is through reading. This helps one through insights into the way people from different cultures act and think when faced with similar problems.

*Improves Concentration –* When a student finds something interesting to read, he/she becomes part of the story. This provides a clear focus on the subject and also exercises his/her brain to think ahead and try to analyze the next steps.

*Builds Self Esteem –* Books and articles on true stories of leadership or overcoming challenges provide a simple way to boost one’s self esteem.

*Students get inspired thinking* – “If they can, why can’t I?”

```Following are some tips for cultivating the habit of reading:```

• Start early. You can enjoy reading the Reading Primers first.

• Model good reading habits by watching others who are fond of reading.

• Read aloud with good reading skill modeled by the librarian or teachers.

 • Read for pleasure. Just explore without purpose of studying for exam.

• Read high-quality books. Reading books by great minds leads to great thoughts.

• Visit a library regularly or buy books from book stores to create your own.

How important is Reading?🤔🤔🤔

*वाचण्याची सवय*

*"वाचन संपूर्ण मनुष्य बनवते" - फ्रान्सिस बेकन*

जर चालण्याने संपूर्ण शरीराच्या स्नायूंसारख्या व्यायामासाठी मनाच्या वाचनाची सवय लावली जाऊ शकते - तर यामुळे मनाचे सर्व गुण विकसित होतात. वाचनाची सुरुवात अगदी लहान वयातच होऊ शकते आणि विद्यार्थी उच्च ग्रेडमध्ये आणि त्याही पलीकडे जात असताना हे चांगले होते. अभ्यासाने हे सिद्ध केले आहे की दीर्घकाळ यशस्वी होण्यासाठी आजीवन वाचनाची सवय लावणे आवश्यक आहे. खासकरुन तरुण विद्यार्थ्यांसाठी वाचण्याचे काही फायदे येथे आहेत.

*मानसिक क्षमता विकसित करते* - वाचनाने मनाची विचार करण्याची क्षमता मोठ्या प्रमाणात विकसित होते. त्याऐवजी ते एखाद्या विषयावर आणि लोकांवर विचार करण्यास सक्षम करते जे वाचकांना कधीच अस्तित्वात नव्हते असे वाटते.

*शब्दसंग्रह समृद्ध करते -* वाचनाच्या वेळी शिकलेले नवीन शब्द आणि वाक्प्रचार विद्यार्थ्यांची भाषा समृद्ध करतात ज्यामुळे सर्व विषयांमध्ये तिची समजूतदारपणा आणि अभिव्यक्ती सुधारू शकते.

*मनाची क्षितिजे विस्तृत करते -* या जगात अस्तित्त्वात असलेल्या विविध संस्कृती आणि पद्धती समजून घेण्याचा सर्वात सोपा मार्ग म्हणजे वाचन होय. वेगवेगळ्या संस्कृतींमधील लोक अशाच प्रकारच्या समस्यांसह कार्य करताना आणि विचार करण्याच्या दृष्टीकोनातून एखाद्यास मदत करते.

*एकाग्रता सुधारते -* जेव्हा विद्यार्थ्याला एखादी गोष्ट वाचण्यास आवडते तेव्हा ती / ती कथेचा भाग बनते. हे या विषयावर स्पष्ट लक्ष केंद्रित करते आणि पुढच्या चरणांचे विश्लेषण करण्याचा प्रयत्न करण्यापूर्वी त्याच्या मेंदूचा अभ्यास करतो.

*आत्मसन्मान वाढवते -* नेतृत्व किंवा खर्‍या आव्हानांवर विजय मिळविण्याच्या सत्य कहाण्यांवरील पुस्तके आणि लेख एखाद्याचा आत्मविश्वास वाढविण्याचा सोपा मार्ग प्रदान करतात. विद्यार्थ्यांना विचारसरणीची प्रेरणा मिळते - *“जर ते शक्य असेल तर मी का करू शकत नाही?”*

*वाचनाची सवय लागण्याकरिता काही टीपा खालीलप्रमाणे आहेतः*

1. लवकर प्रारंभ करा. आपण प्रथम प्रायमरी पासूनच वाचण्याचा आनंद घेऊ शकता.

२. वाचनाची आवड असणाऱ्यांना इतरांना पाहुन आधुनिक वाचनाची सवय लावा.

३. ग्रंथपाल किंवा शिक्षकांनी केलेल्या चांगल्या वाचन कौशल्याचे मोठं-मोठ्याने वाचुन वाचनाची सवय लावा.

 ४. आनंदासाठी वाचा. परीक्षेच्या अभ्यासाच्या हेतूसाठी फक्त वाचू नका.

५. उच्च प्रतीची पुस्तके वाचा. मोठ्या मनाने पुस्तके वाचल्याने मोठे विचार मनात येतात.

6. एखादी लायब्ररी नियमित भेट द्या किंवा स्वतःची तयार करण्यासाठी पुस्तक स्टोअरमधून पुस्तके खरेदी करा.

5 . Introduction to Euclid's Geometry 

Equivalent Versions of Euclid's Fifth Postulates

There are several equivalent version of this postulate.

One of them is:

"For every line and every point P not  lyineg on L, There exist new line 'N' passing to P & parallel to L."

       OR

"Two distance intersecting lines cannot be parallel to the same line."

Ex .Digram :

Exercise 5.2 

Que.1] How would you reside euclid's fifth postulate so that it would be easier to understand?

Ans: Two lines and said to be parallel to each other if-

I) They do not intersect at any point 

ii) They are equal distance from each other.

iii) a = b {Distance between two parallel lines are equal.}

Que.2] Does euclid's fifth postulate imply the existence of parallel line? Explain.

Ans :  Yes, according to euclid's fifth postulate imply the existence of parallel lines.

{ From fig. 1 }

Angle 1 +Angle 2 <180°

Angle 3 +Angle 4 > 180°

Thus, the line will meet on producing. 

But if { from fig .2 }

Angle 1+ Angle 2= 180 °

Angle 3 +Angle 4 = 180°

So, the line will not meet on producing on either of sides.

Hence, it can be said to that parellel lines exist .

{With extra information} Exercise 5.1 NCERT solution Lesson no. 5 . Introduction to Euclid's Geometry.

Lesson no. 5 . Introduction to Euclid's Geometry

Geo- Earth 

Metry- Measure

Geometry appear to have originated from the need for measuring land.

Euclid's Geometry-

It is the study of plane and solid figure on the basis of axioms, theorems , postulates compelled by Euclid in his book "The element"

Untilled 1900 geometry implied euclidean geometry as there was no other form of geometry at that time. Recently non- euclidean geometry system has been developed.

Euclid's Definitions-

Euclid give more than hundred definition in the book

I) A point  is that which has no part.

ii) A line is breathless length.

iii) A  surface is that have length and breadth only .

iv) parallel line are those which do not meet.

Axioms- 

Axioms are common notion, any discipline not only restricted to geometry .These are universal truth some Axioms are given below:

I) whole is greater than a part.

ii)things which are equal to same thing are equal to each other.If a=x,b =x than ,a=b

iii) if equal are added to equal then the whole are equal. If a = b than, a +x= b+x

Postulates: 

Postulates are specific to Euclid geometry. There are five postulates given below: 

I) The unique straight line may be drawn from any point to any other point.

ii) A terminated line can be produced in definitely .

iii) A circle can be drawn with any centre and any radius.

iv) All right angles are equal to one another.

v) If a straight line falling onto a straight line makes the interior angle , on the some side of it taken together less than two right angle, then the two straight lines produced in definitely meet on that side in which sum of angle  less than two right angles.

Consistent: 

It was not possible to diduce  any statement using this Axioms, that contradict any axioms ,This  this system is taken as consistent.

Propositious/ Theroms : 

Statement that were true with the help of axioms  and postulate are called theorem.

Ex . Diameter divided circle into parts.

Exercise 5.1

Q1. Give definition for each of the following terms.are there other terms that need to be defined first? What are they and how might you define them?

i) parallel lines

Ans : parallel lines are straight lines which are in the same plane and perpendicular distance between this line is always constant and never intersect each other.

ii) perpendicular line

Ans: Two lines are said to be perpendicular line if the angle between them is a right angle.

iii) line segment

Ans : a straight line drawn from any point to any other point is called a line segment.

iv) radius of a circle

Ans:it is the length of a line segment joining the centre of circle to any point on the circle.

v) square
Ans: a square is a 4 sided figure which is both equilateral and right angle.

Q2.  A  point  C lies between two points A and B such that AC=BC , then prove that AC=1/2 AB .
Explain by drawing the figure.

Ans :  

Given,
AC =BC
To prove that AC= 1\2 AB 
Proof :  it is given that AC= BC ...........{1 }

Since , C lies between A& B
AC +AC =AB 
2AC= AB 
AC =1/2 AB.      [  From eq { 1}]

Q 3.   In question 4 point C is called a midpoint of line segment AB .prove that every line segment has one and only one midpoint.

Ans:

Let C&D are two midpoint of AB .

C is the midpoint of AB
AC =BC .............{1}
C lies between A & B ...... [from eq 1]
AC +CB= AB 
AC+ AC =AB 
2AC =AB ................{2 }
Since, D is the midpoint of AB 
AD= BD
D lies between A&B
AD +DB =AB 
AD +AD =AB 
2AD =AB .............{3}
[From eq 2 & 3]
2AC = 2AD 

AC=AD .
[Things which are halve of the same things are equal to one another.]

Karate Basic

Karate

Karate is a Japanese martial art that focuses on defensive and counter  attacking skills. It is practised strictly as an art, for self defence purposes, or as a competitive combat sport, However , karate is not just sport ; it is a method of self discipline through which the practitioner (called karateka) can straighten their character. 'kara ' means in empty & 'te' means hand .It is mean of defending oneself without protection.

•There are three types of karate practices: 

[i] kihon(drilling of fundamentals that include blocks, punches ,stance kids and strikes), 

[ii]kata (sequence of movement used in combat) .

[iii] kumite( sparring).

At competency level, the students become acquainted with basic skills of karate such as adopting the front stance, performing a punch and blocking a punch. At proficiency level, the students learn how to perform karate kicks.

Punch

1. The lunging punch or oi-zuki can be performed starting with the front stance. shoes which should be your punching hand and which were blocked in head. The blocking hand should be in front, and punching hand should nestle against your hip.

Front kick

• The front kick need little bit of practice, to make it perfect. It is also called Mae geri, each one of the fundamental moves of karate. It aims at the opponent's Legs ,groin,  throat , face or solar plexus.
• Adopt a stance; the dominant leg should be behind the other leg with its to its side.The toe of the other leg is pointed straight forward.The torso face the direction of the dominant leg ,while the hands are raised in protection.

Rules of karate 

The goal of karate match is to defeat the opponent using punches kicks and throws to score points

.

The competitor who score the highest points at the end of kumite( fight) wins.The match close sunary the winner has an eight point lead over the opponent.a match can also end when one of the competitors is unable to carry on due to injury or disqualification..

Karateka (karate players) during a match

In karate a square mat measure 8 metre × 8 metre with an additional 1 metre on all sides the safety area is used.

the competitors board to each other before the start of kumite.

the match can only begin when the referee shouts"shobuhajime!"

To suspend the match the referee shouts" yame!"&     

"Tsuzuketehajime!"to resume it.

To end the match the referee shouts "soremade!"

There are three types of scores that can be won:

Yuko=1pt

Waza-ari=2pt

{Part 1}

 Q]What is the motion? & explain with example.

Ans:    When the object change its position from one place to another is called as motion.

   Ex -

• A moving car
•  ball 
• cycle 
• pendulum

  Q.1] An object has moved through a distance can it have zero displacement if yes support your answer with an example.

Ans:   Yes because when an object move and come on it initial position it means it's displacement is zero.

Ex -

Q.2 ]   A farmer moves along the boundary of a square field of side 10 metre in 40 seconds what will be the magnitude of displacement of farmer at the end of 2 minutes 20 seconds for its initial position?

Ans:

case.1.( speed of farmer)- {Sf}

Sf=distance/ time

Sf=40/40 (m/s)
✓Sf =1 m/s

 Case.2.

S=1m/s (metre per second )
Time = 2 minute 20 seconds
1min=60sec
2min=2×60
          =120
t (Time)= 120×2
              =140sec

                                 
d (distance )  =speed (s)×Time(t) 

=1×140
=140m/s

= 140/40
=7/2
=3.5

                :. At the end of 2 minutes 20 seconds from his initial position it cover 3.5 metre.

Displacement=AC
     2      2     2
AC =AB +BC
           2      2
     =10+ 10
=100+100
=√200
     

Q.3) Which of the following is true for displacement.

1] It can not be zero.
  -------False

2] Its magnitude is greater than the distance travelled by the object.

 ------- false

Q 1] Distinguish between speed and velocity.
Ans: 
Speed---

• Speed does not have a direction.
• Speed is measured in metre per second
• Speed it is the  sector quantity.
• Speed can never be negative or zero ,it is only positive.
• Speed never decrease with time.
• Speed main aur may not be equal to velocity.
• v=d/t, were v- (s)speed, d- distance & t- time

Velocity---

• Velocity is speed with direction.
• Velocity is aslo measured  in metre per second
• Velocity is vector quantity
• Velocity can be zero negative or positive.
• Velocity can decrease with time.
• an object may possess different velocity but the same time. 
• ∆x/∆T, were. ∆T= Time of arrival & ∆x =displacement.

Q.2] Under what condition(s) is the magnitude of average velocity of an object equal to its average speed?

Ans:   Average velocity would be equal to average speed when the total distance travel = the net displacement of a particle.This happen when a particle moves along a straight line in a fixed direction.

Q.3]. What does the odometer of an automobile measure?
Ans:
Odometer is the device which measure the distance travelled by an automobile based on ,the perimeter of the wheel as it  rotates.

Q.4]. What does the path of an object look like when it is in uniform motion?
Ans:
Uniform motion is the motion in which the velocity vector remain constant at every point of time so, that the path of an object look like straight line when it is in uniform motion &  object is moving in a straight path with uniform acceleration.

Q.5]  During an experiment, a signal from a spaceship reaches the ground station in 5 what was the distance of the spaceship from the ground .What was the distance of the spaceship from the ground station the signal travels at the speed of light that is 3×10 power of 8 m/s.

Ans:  1 min=60 sec
          5min= 5× 60=300sec
So, distance= speed* time
                      =300*3*10power of 8
                      =900×10 to the power of 8
                      =9×10  to the power of 10

Q.1] When will you say a body is in

(i) uniform acceleration?
Ans: When an object change its velocity by equal interval of time then we say that the object is in uniform acceleration.

(ii)Non uniform acceleration.                     
Ans:.      An object change it velocity by unequal interval in equal interval of time then we say that object is in non uniform acceleration .                                                       

                                                                              

Q.2] A bus decreases its speed from 80km h to 60 km h in 5 s . Find the acceleration of the bus.

 Ans: initial velocity u= 80 km h.                                    Final velocity v= 60km h.                        

Time t = 5 s.                 

SI  unit of velocity= m/s         

                                  

                    1km= 1000m.          

u= 80 *1000= 80000m/s

v= 60*1000=60000 m/s

Acceleration of the bus= v-u / t= 60,000-80,000/5=

-20,000/5=

-4000m/s

:.Therefore the acceleration of the bus is -4000 metre per square.

Q.3] A train starting from a railway station and moving with uniform acceleration attains a speed 40 kilometre in 10 minutes. Find its acceleration.

Ans: u=0( initial position)

         v= 40 (final position)

         t= 10 min

Acc= ?

Formula of acceleration= v-u/ t

                                           =40-0/10

                                             =40/10=4km per min

             

Exercise

Q.1) An athlete completes one round of a circular track of diameter 20 metre in 40 seconds what will be the distance covered and displacement at the end of 2 minutes 20 seconds?

Ans:. the diameter of circular track =200
 radius of circular track is equals to 200/2 =100

• Time taken by the athlete for one round =40 sec
• Distance covered by athlete is in one round. (s) =2×πr    
• 2×22/7×100 
• Speed of athlete =distance /time
• 2×2200/7×40=4400.                                                                distance= 2200m                        Displacement=200m

Q.2 ] Joseph jogs  from one end  to the other end B of a straight 300 m road in 2 minutes 30 seconds and then turn around and job 100m back to point C in another 1 minute .What are Joseph 's average speed and velocity in jogging from  to( a) from A to B & (b) from A to C?

Ans: 

Total distance  covered from AB=300m
Total time taken =2*60 +30s =150s

Therefore, average speed from AB=distance divided by total time=300/150=2m/s

Therefore, velocity from AB= displacement AB/time= 300/150=2m/s

Total distance covered from AC=AB+BC
                                                        =  300+200
                                                        =  500
Total time taken from A to C= time taken for AB&BC
=(2*60+30)60s
=210s
:. Therefore, average speed from AC=Total distance/total time=400/210= m/s
                                                   =1.904m/s
Displacement(s) from A to C=AB-BC
                                                  =300-100m
                                                  =  200m
:.  Therefore  velocity from AC=displacement/time=200/210m/s=0.952m/s

      Q. 3]   Abdul while driving to school computes the average speed for his trip to be 20 km per hour on his return trip along the same route there is less traffic and average speed is 30 kilometre per hour what is the average speed of Abdul trip ?

Sol'n :   

Average speed=20km/h

Due to less traffic average speed is=30km/h

Average speed =?

(By formula 2xy/x+y)=2*20*30/20+30

                                     =1200/50

                                     =24km/h
