Question= What is resistance.
Answer= The resistance of a conductor is said to be 1 ohm if a current of 1 ampere flows through it when the potential difference across it is 1 volt.

What is resistance.

Question= What is barometer.
Answer= Barometer is an instrument which is used to measure the atmospheric pressure.
There are three types of barometer are commonly used.
{1} Simple barometer.
{2} Fortin's barometer.
{3} Aneroid barometer.

What is barometer.

Question= What is Speed.
Answer= The speed of a body is the rate of change of distance with time. Numerically it is the distance travelled by the body in 1 s.

What is Speed.

Question= What is Primary cells ? 

Answer= These are the cells which provide current as a result of irreversible chemical reaction. These cells are discarded after use when the entire chemical energy in them has converted into electrical energy. Thus these cells are 'use and throw ' type of cells and cannot be recharged. Depending upon the material of electrodes, we have different of primary cells e.g. simple voltaic cell, Leclanche cell, Daniel cell, dry cell, etc.

What is Primary cells ?

Question= What is Temperature.
Answer= Temperature is a quantity which tells the thermal state of a body ( i.e., the degree of hotness or coldness of the body.) It determines the direction of flow of heat when two bodies at different temperature are placed in contact.

What is Temperature. +Harsh Puri Goswami 

Question= What is Logical Errors.
Answer= A logical errors (sometimes called a semantic error) is a bug in a program that causes it to operate incorrectly, but not to terminate abnormally (or cash ). A logic error produce unintended or undesired out put or other behavior, although it may not immediately be recognized as such

What is Logical Errors. +Harsh Puri Goswami 

Question= What is Heat.
Answer= Heat is a form of energy which flows. It is the energy of random motion of molecules constituing the body.

What is Heat. +Harsh Puri Goswami 

Question= What is Modern Periodic Table.
Answer= Dobereiner's  Triads, Newland's Law of Octaves, Mendeleev's contributions; Modern Periodic Law, The Modern Periodic Table (groups and periods.

What is Modern Periodic Table. +Harsh Puri Goswami 

Question= What is nucleus.
Answer= The protons and neutrons are found- in the centre or nucleus of the atom.

What is nucleus. +Harsh Puri Goswami 

Question= What is an element.

Answer= Answer= An element is a pure substance made up of one kind of atoms- having the same atomic number and which cannot be broken down- into two or more substances by any physical or chemical means.

What is an element. +Harsh Puri Goswami 

Question= What is an atom.

Answer= An atom is the smallest particle of an element which can take part- in a chemical reaction and is consider the basic unit of matter, e.g .O,CL are atoms.

What is an atom. +Harsh Puri Goswami 

Question= Modern atomic theory.
Answer= {1} Atoms are- divisible and destructible.
{2} Atoms are divisible- consisting of subatomic particles like- electrons, protons and neutrons.
{3} Atoms of the same element- may not be alike in all respects as seen in case of isotopes which are atoms of the- same element having the same atomic number but different mass number.

Modern atomic theory. +Harsh Puri Goswami 

Questions= Dalton's atomic theory
Answer= {1} Atoms are- indivisible and indestructible.
{2} An atom is the smallest indivisible particle of an element.
{3} Atoms of the same element are- alike in all respect and- differ from atoms of other elements.

Dalton's atomic theory. +Harsh Puri Goswami 

Question= The Constitution (74 Amendment) Act, 1992
Answer= In many States local bodies had become weak and ineffective on account of a variety of reasons including the failure to hold local regular election. As a result Urban Local Bodies were not able to perform effectively as vibrant democratic units of self- government.

The Constitution (74 Amendment) Act, 1992. +Harsh Puri Goswami 

Question= What do you understand by the object-oriented model of programming.

Answer= Object oriented model of programming means a methods of implementation in which programs are organsied as coaperative collection of object each of which represent an instance of a class whose classes are all members of a hierarchy of classes untied via inheritance relationship. It follow bottom up apporach (function are divide and combined to make one main programm. 

What do you understand by the object-oriented model of programming. +Harsh Puri Goswami 

Question= What is a state of object.
Answer= The state of object can be defined as per an example. A dog state will his (name, colour, breed etc.) 

What is a state of object. +Harsh Puri Goswami 

Question= How are abstraction and encapsulation related.
Answer= Encapsulation is related by abstract in as encapsulation is wrapping up of data preventing it from being acessed by out where as abstraction id the hiding of lower level details. 

How are abstraction and encapsulation related. +Harsh Puri Goswami 

Question= Why is data considered safe when encapsulated.
Answer= The data is considered safe when encapsulation as it perform the function of wrapping the data to prevent roaming of it. It also keep data safe from being asscesed from outside. 

Why is data considered safe when encapsulated. +Harsh Puri Goswami 

Question= What are parameters used for.
Answer= The messages which function use to communicate are in the form of parameters. 

What are parameters used for. +Harsh Puri Goswami 

Question= What do you understand by message to an objects.

Answer= When function of different object use to communicate with each other they use a communication medium termed as message.

What do you understand by message to an objects. +Harsh Puri Goswami 

Question= What is the behavior of an object. Explain with an example.
Answer= The behavior can be explained by an example like. A dog will have its specific behavior like barking fething and wagging tail.

Question= What is an object.
Answer= An object is a software bundle of variable and related methods objects has its own charaterstics and behavior.

Question= Explain now the real-world object get simplified using abstraction.
Answer= Abstraction helps us make us drive a car listen to music on the stereo, without be overhelmed by the complexity of pats that from the car or the stereo.

Question= Explain what do you understand by abstraction.
Answer= Abstraction is the representation of essential features of a system without getting involved with the complexity of the entire system. It can also be hiding of cover level detail.

Question= Why leap year comes after four years.                                                                             Answer= February 29 is a date that usually occurs every four years, and is called leap day. This day is added to the calendar in leap years as a corrective measure, because the Earth does not orbit around the sun in precisely 365 days.

Why leap year comes after four years.
