the part away from the sun has night. Thus, when it is night in
America, it is day in India.
2. The Earth takes 365 ¼ days to complete one revolution. This ¼
day is balanced by adding up together for 4years in a row, which
gives an additional 24hours or one day. After every 4years, this
day is added in the month of February. Thus February gets 29 days
in that year. The year with 366 days is known as a leap year.

CHAPTER- In a tunnel – E.Nesbit
In a tunnel by E. Nesbit describes what it is like to going into
a tunnel, by a train. When the grown-up people pull up the window
and hold them by the strap and the railway carriage suddenly grows
like night, then slowly the darkness disappears as the train moves
out of the tunnel. But everything is quite different when one walks
into a tunnel. This story describes one such experience by three
children namely, Peter, Phyllis, and Bobbie who walks into a tunnel
and faces an advancing train passing the tunnel.
2. Answer the following questions:
a. Why are the carriage windows pulled up when the train goes
through a tunnel?
The carriage windows are pulled up when the train goes through a
tunnel because the noise of the running, rattling train suddenly
changes and grows different and much louder.
b. What kinds of things do you see in a tunnel (when you are on
foot)?
Things that can be seen in a tunnel when you are on foot are,
slimy, oozy trickles of water running down the inside of the
tunnel, notice that the bricks are not red or brown as they are a
the tunnel's mouth but dull, sticky, sickly green. The voice, when
one speaks is quite changed from what it was outside in the
sunshine, and it is a long time before the tunnel is quite
dark.
c. How many children are there in the tunnel?
There were three children in the tunnel. There were Peter,
Phyllis and Bobbie.
d. Which child is the most frightened?
Bobbie is the most frightened among the three children.
e. Peter asks the others: 'and what’s that'? What is 'that'
refer to?
He refers to the low humming sound on the railway line, a
trembling of the wires, a buzzing, humming sound that grew louder
and louder as they listened.
f. What are the wires over which Peter stumbles?
The wires over which Peter stumbles were the wires of
telegraph.
g. How does the author describe the train ' hurtling by'?
The author describes the train 'hurtling by' as with a rush and
a roar and a rattle dazzling flash of lighted carriage windows, a
smell of smoke and blast of hot air, the train hurtled by, clanging
and jangling and echoing in the vaulted roof of the tunnel.

Chapter: Rational Numbers.
Study item: Problems on rational numbers.
Multiplication of rational numbers means multiplication of two
or more rational numbers.
Therefore, multiplication of two rational numbers
=multiplication of their numerators/multiplication of their
denominators.
Example: 5/6×(-3/4) = 5×-3/6×4= -15/24= -5/8.
(-3/8)×3= -3/8×3/1 = -9/8.
Multiplicative inverse: Reciprocal of a rational number is
called multiplicative inverse.
Example: multiplicative inverse of 3/4 is 4/3.
And multiplicative inverse of -4/5 is 5/-4.
Division of rational numbers: If a/b and c/d are two rational
numbers such that c/d not equal to zero, then a/b ÷c/d =a/b ×
(multiplicative inverse of c/d) =a/b ×d/c.
Example: 5/6 ÷ 9/7
5/6 × (multiplicative inverse of 9/7)
= 5/6×7/9
= 35/54.

1. Sugar act:-
Sugar act also called plantation act or revenue act (1764)in U.S
colonial history. The colonists could no longer buy sugar from the
French colonies at cheap rates. The British officials enforced the
act and collected the tax strictly.
2. Stamp act:-
Starting with the sugar act of 1764, which imposed new duties on
sugar and other goods, the British government, began to tighten its
reins on the colonies. It roused widespread protest from the
colonies.
3. Declaratory act:-
Declaratory act declaration by the British parliament that
accompanied the repeal of the stamp act. It stated that the British
parliament's taxing authority was the same in America as in Great
Britain. The colonists raised the cry of no taxation without
representation.
4. Townshend’s duties:-
Chancellor of the exchequer Charles Townshend also tried to
solve the problem of the American colonies. In the Boston Massacre
three colonists were killed by the British soldiers. This was
widely resented by the colonists.
5. Withdrawal of duties:-
Lord North, who came to power in the 1770s as the Prime minister
tried to improve the situation in the colonies.
6. Boston tea party:-
The British parliament abolished duties on paper and glass but
retained the tax on tea. A group of men disguised as red Indians
forced their way into the ships which had brought tea for sale to
colonists. They threw the crates of tea into the sea. This incident

Structure of Atom
Atomic Structure of Isotopes
The isotopes of an element have the same number of
protons but differ in the number of neutrons.
The atomic structure of an isotope is described with the help of
the chemical symbol of the element, the atomic number of the
element, and the mass number of the isotope. For example, there
exist three known naturally occurring isotopes of hydrogen,
namely, protium, deuterium, and tritium.
Isotopes of Some Elements
· Hydrogen
The most abundant isotope of hydrogen on the planet Earth is
protium. The atomic number and the mass number of this isotope are
1 and 1 respectively.
· Carbon
Carbon has two stable isotopes – 12C and 13C. Of these isotopes,
12C has an abundance of 98.9%. It contains 6 protons, 6 electrons,
and 6 neutrons.
· Oxygen
There exist three stable isotopes of oxygen – 18O, 17O, and 16O.
However, oxygen-16 is the most abundant isotope.
Question 5.

Solution:
(a) Atomic number: The number of protons present in an atom is
known as Atomic number. It is denoted by Z. Example: An atom of
oxygen contains 8 protons. Therefore its atomic number is 8.
(b) Mass number: The sum of the number of protons and neutrons
present in the nucleus of an atom is known as the Mass number and
it is denoted by A.
I.e. Mass number = Number of protons + Number of neutrons.
(c) Nucleons: The protons and neutrons collectively are known as
nucleons.
(d) Valence Shell: The outermost shell of an atom is known as
its valence shell.
BIOLOGY
Chp- 1: Transport of water &Minerals in plants.
Today we discuss about the movement of water and minerals from
root to leaves.
We also discuss about the processes through which it actually
moves.
Q7. Describe the process of ascent of sap or, Describe movement
of water molecules.
Ans: Water molecules move in plants in three ways - diffusion,
osmosis and active transport.
The concentration of water in soil is higher as compared to root
cells.
• Water enters the root cells from the soil through osmosis.
• The concentration of water and minerals is same in all root
cells.
• When water enters the root cells, its concentration increases
as compared to the adjacent cortex cells.
• Water moves from the root have cells to the cells of the
cortex, then endodermis, then peri cycle and finally reaches the to
xylem tissue though osmosis.
• The upward movement of water and minerals in a plant through
Xylem is called ascent of sap.
• Unlike water, the concentration of minerals is more in the
root hair cells than in the soil, so it needs energy.
• The movement of particles from a region of lower to higher
concentration by utilizing energy - Active transport.
• When the concentration of minerals in soil is higher than root
hair, they enter the root hair cells through diffusion.

Here we will learn about change of state, that is solid to
liquid and liquid to gas and vice-versa
Change of State
Fusion or Melting
The process by which a substance’s solid state change into the
liquid state at a constant temperature by absorption of heat is
known as fusion or melting and the fixed temperature at which the
melting occurs is known as the melting point.
Example: Ice (solid) melts into water (liquid) at a temperature
of 0C.
Vapourisation or Boiling
The process by which a substance’s liquid state changes into the
vapour or gaseous state at a constant temperature by absorption of
heat is known as vapourisation or boiling and the fixed temperature
is known as the boiling point or vapourisation point of the
liquid.
Example: Water (liquid) vapourises to steam (gas) at a
temperature of 100C.
Condensation
The process by which gas changes into the liquid state at a
constant temperature by releasing heat is known as the condensation
or liquefaction and the fixed temperature is known as the
condensation temperature.
Example: Steam (gas) condenses to water (liquid) at a
temperature of 100C.

Chapter: Expansions.
Study item: expansions.
(a+b)2= a2 + 2ab + b2
Here , a2+ 2ab +b2 is called the expansion of (a+b)2.
Example: (2x+ 7y)2 = (2x)2 + 2 (2x) (7y) + (7y)2
= 4x2 + 28 xy +49y2
(3x + 1/2x)2 = (3x)2 +2 (3x) (1/2x) + (1/2x)2
= 9x2 +3+1/4x2
(a – b )2 = a2– 2ab + b2
Example: (3x – 1/2x)2
= (3x)2– 2 (3x) (1/2x) +(1/2x)2
= 9x2 -3 + 1/4x2
(5x - 9y)2 = (5x)2 – 2(5x)(9y) + (9y)2
=25x2 – 90xx + 81y2
(a+b)(a-b) = a2– b2
Example: (x+3)(x-3)
= (x)2 –( 3)2
= x2– 9
( 7p + 9q)(7p - 9q)
= (7p)2– (9q)2
=49p2 - 81q2
(x+a) (x+b) = x2 +(a+b)x +ab
Example: (x+3)(x+5)
= x2 + (3+5)x +(3×5)
=x2 + 8x +15
(x+a)(x-b) =x2 +(a-b)x -ab
Example: (x-7)(x+9)
= (x)2 +( 9-7)x –(9×7)
=x2 +2x -63.

CHEMISTRY
Writing Chemical formulae
For Convenience, every compound is represented by a formula. The
following steps should be taken while attempting to write a
formula. The method is called Criss-cross method.
(i) Write the symbols side by side, basic radical
(ii) Write the valency of each atom on top of its symbol.
(iii).Divide the valency numbers by their highest common
(H.C.F), if any, to get the simple ratio. Ignore the (+) or (-)
symbols of the radicals.
(iii)Write the interchanged valency numbers to the lower right
of the radicals. If the radical is a group of atoms and has a
valency number more than 1.enclose it within brackets.
E.g:
(i)Name of The CompoundMagnesium Chloride.
Symbol with valencyMg2+ Cl-
Exchange of valencyMg1 Cl2
FormulaMgCl2
(ii).Name of the CompoundAluminium hydroxide
Symbol with valencyAl3+ (OH)-
Exchange of ValencyAl1 (OH)3
FormulaAl(OH)3
BENGALI(2ND LANGUAGE)
প্রথম অধ্যায়-গিন্নি (রবীন্দ্রনাথ ঠাকুর)
১।"তখন সে নিরতিশয় কাতর হইয়া পড়িল"-
ক) সে বলতে কাকে বোঝানো হয়েছে?
খ) প্রসঙ্গ কি?
গ) তার কাতর হয়ে পড়ার কারণ কি?
ঘ) কাতর হবার পরতার কি অবস্থা হয়েছিল?
উ- ক) রবীন্দ্রনাথ ঠাকুর রচিত "গিন্নি “ গল্পে সে বলতে শশীশেখর কে
বোঝানো হয়েছে।
খ)শিবনাথ পণ্ডিত রাগ বশত নিজের খুশি চরিতার্থ করার জন্য ছাত্রদের
নতুন নতুন নামকরণ করতেন। সেই নামকরণ ছাত্রদের কাছে মর্মপীড়ার কারণ
হতো- সেই প্রসঙ্গে এই উক্তি।
গ) শশীশেখরকে পণ্ডিত মশাই তার চেহারার সঙ্গে সামঞ্জস্য রেখে নাম
রেখেছিলেন ভেটকি। কিন্তু শশীশেখর তার চেহারার সঙ্গে সামঞ্জস্য রেখে
নামকরণ করা হয়েছে কিনা ভেবে পারছিল না। যদি তাই হয় তা অত্যন্ত লজ্জার
কারণ। কারণ তার চেহারা টা ভেটকি মাছের মত চওড়া তা কারও বুঝতে বাকি
থাকেনা। তাই সকলের সামনে তার এই নামকরণ মর্মযন্ত্রণাকে দ্বিগুণ বাড়িয়ে
দেয়।
ঘ) শিবনাথ পণ্ডিত শশীশেখরকে ভেটকি বলে সকলের সামনে নামকরণ করার ফলে
সে কাতর হয়েছিল কারণ সে কিছুতেই বুঝে উঠতে পারছিলনা কেন পণ্ডিতমশাই
তার এমন নামকরণ করলেন। যদি তার চেহারার সঙ্গে সাদৃশ্য রেখে এই নামকরণ
করে থাকেন তাহলে তা অত্যন্ত লজ্জাজনক ও মর্ম পীড়াদায়ক, এই অপমান করার
জ্বালা শশীশেখর কিছুতেই মেনে নিতে পারছিল না।
২।'’ ইহা হইতে এই তত্ত্ব পাওয়া যায় "-
ক) "ইহা হইতে” বলতে কি বোঝানো হয়েছে?
খ) কোন তত্ত্ব পাওয়া যায়?
গ) বক্তা কে?
ঘ) এই তত্ত্বের প্রমাণ স্বরূপ গল্প অনুসারে একটি ঘটনার কথা উল্লেখ
করো।
উ-ক) ইহা হইতে বলতে নামের বিকৃতিতে মানুষের মনে কীরূপ দুঃসহ আঘাত
লাগে-তার প্রাণের চেয়ে প্রিয়তর স্থানকে আঘাত করা হয়- তাকেই বোঝানো
হয়েছে।
খ)তত্ত্বটি হল-মানুষ বস্তুর চেয়ে অবস্তুকে বেশি মূল্যবান শ্রেয় মনে
করে, প্রাণের চেয়ে মানকে বড়ো মনে করে, আর আপনার চেয়ে আপনার নাম কে
বড়োমনে করে।
গ) আলোচ্য উক্তিটির বক্তা হলেন রবীন্দ্রনাথ স্বয়ং।
ঘ) এই প্রসঙ্গে আশুর গিন্নি নামকরণের কথাবলাযায়। ক্লাসে সকলের
সামনে পণ্ডিত আশুর এই ধরনের নামকরণের ফলে আশুর লজ্জায় মাথা নত হয়ে
যায়। ক্লাসের সকলে আশুকে গিন্নি গিন্নি বলে ডাকতে শুরু করে। অনেক সুখ
দুঃখের দিন এসেছে-কিন্তু সেদিন কার ক্লাসের মধ্যে পণ্ডিত মশাইয়ের
গিন্নি নাম করণের সঙ্গে আর কিছুর তুলনা করা যায়না।

Introduction to Object Oriented Programming concepts
Today’s topic: Operators in Java.
Operator in Java is a symbol which is used to
perform operations. For example: +, -, *, / etc.There are many
types of operators in Java which are given
below:
· Unary Operator,
· Arithmetic Operator,
· Shift Operator,
· Relational Operator,
· Bitwise Operator,
· Logical Operator,
· Ternary Operator and.
· Assignment Operator.
*Unary Operator: Java unary operators are the types that
need only one operand to perform any operation like
increment, decrement, negation etc. It consists of various
arithmetic, logical and other operators that operate on a
single operand.
*Arithmetic Operator: Arithmetic operators are used
in mathematical expressions. Arithmetic
operators are + (addition), - (subtraction), *
(multiplication), / (division) and % (reminder). Java provides
built-in short-circuit addition and subtraction operators
*Shift Operator: A shift operator performs bit
manipulation on data by shifting the bits of its first
operand right or left.
*Relational Operator: Java has 6 relational
operators.
== is the equality operator. This returns true if both the
operands are referring to the same object, otherwise false.
!= is for non-equality operator.
< is less than operator.
> is greater than operator.
<= is less than or equal to operator.
>= is greater than or equal to operator.
*Bitwise Operator: Bitwise operators are used to perform
manipulation of individual bits of a number. They can be used with
any of the integral types (char, short, int, etc). They are used
when performing update and query operations of Binary indexed
tree.
1. Bitwise OR (|) –This operator is binary operator, denoted by
‘|’. It returns bit by bit OR of input values, i.e, if either of
the bits is 1, it gives 1, else it gives 0.
2. Bitwise AND (&) –This operator is binary operator,
denoted by ‘&’. It returns bit by bit AND of input values, i.e,
if both bits are 1, it gives 1, else it gives 0.
3. Bitwise XOR (^) –This operator is binary operator, denoted by
‘^’. It returns bit by bit XOR of input values, i.e., if
corresponding bits are different, it gives 1, else it gives 0.
4. Bitwise complement (~) –This operator is unary operator,
denoted by ‘~’. It returns the one’s compliment representation of
the input value, i.e, with all bits inversed, means it makes every
0 to 1, and every 1 to 0.
Answer the following:
1. What are operators?
2. Define the following terms:
*unary operator
* AND operator
* OR operator
* Relational operator
