Once there was an old man. He had four sons. They always quarreled with one another. One fine day he decided to teach them a lesson. He called all his room. As they came and sat in his room. He said to them, "Today I am going to teach you a very important lesson of life. Pay heed to it. There is a bundle of sticks lying in the corner, and I want each one of you to try to break it." All the four sons tried to break it one by one. But no one of them could do it. After all the sons had tried their best and given up, he asked his eldest son, "Now, open the bundle and separate the sticks and try to break them. " Quite easily, each of the four sons broke the sticks easily. The old man said. "Did you see when the stick were bound together, nobody could break them; however, when they were separated, each stick could be easily broken. Similarly, if you remain united like the bundle, no one will be able to break you. But if you fight and live separately, you will be easily broken." The sons understood the lesson. They decided never to fight with one another. They had learnt that unity is strength.

'The printed letters of the old book remains at the same position as they were seen for first time' ,this surprised Margie and Tommy. E-books are electronic books displayed or read on a computer. Again the printed books have texts, images etc. printed on paper and the pages are bound together. The words of the printed books stand still as they are printed on the pages.

In schools, children are exposed not only to new ideas but also to compatriots of the same age group. This instills sociable practices like friendship, participation, empathy, and many more, which turn out to be important in their adulthood.

Define matter. On which classification Types of matter distributed. Also explain the two properties of matter

Posted by Ravinder Singh 2 years, 10 months ago

CBSE > Class 09 > Science

3 answers

Preeti Dabral 2 years, 10 months ago

Matter can be classified into two broad categories: pure substances and mixtures. A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. Mixtures are physical combinations of two or more elements and/or compounds.

Intensive and Extensive Properties of Matter Both the physical and chemical properties of matter are either extensive or intensive. Extensive properties including mass and volume are proportional to the amount of matter being weighed. Density and colour, for example, are not affected by the amount of matter present.

Preeti Dabral 2 years, 10 months ago

Environment as the term itself indicates is anything that surrounds or environs us. Environment in this sense is made of all those things which though distinct from us affect our life or activity in some way. It consists of all surroundings and influences, whatsoever that are present whenever an event occurs.

It refers to those forces, situations, or stimuli that affect the environment from outside. Environment is thus not a simple but a complex phenomenon and consists of various forms such as physical environment, biological environment, social environment and supra-social environment. The physical environment consists of the geographical, the climatic and the controlled geographical environment. The biological environment includes the plant and animals found all round man. The social environment consists of three kinds of environments—economic, cultural and psycho-social environments. The supra-social environment consists of the notions regarding God or supernatural power.

Shamitha Shami 2 years, 10 months ago

Let ABCD be a square When diagonals are constructed we get two triangle that is ∆ ADC and ∆ BCD We have to prove that these triangles are congruent (same) to justify that diagonals are equal. In ∆ADC and ∆ BCD AD =BC (sides) DC =DC (common) Angle ADC = angle BCD (90) So ∆ADC is congruent to ∆BCD AC =BD (CPCT :- coresponding part of congruent triangle ) AC and BD are diagonals of square ABCD In same square let us take the ∆AOD and ∆BOC Note:- here O is the intersection point of diagonals of square In ∆AOD and ∆BOC AD = BC Angle ADO = Angle OBC Angle DAO =Angle OCB (Alternative interior angle) ∆AOD and ∆BOC are congruent AO = OC (CPCT) DO = OB (CPCT) Hence diagonals bisect each other Same way when we prove ∆AOD is congruent to ∆DOC using SSS congruence rule we will get Angle AOD = Angle DOC (CPCT)---------- note 1 let angle AOD = angle 1 let angle DOC = angle 2 When we add angle 1 and 2 we will get 180° Angle 1 + Angle 2 = 180° From note 1 Angle 1= angle 2 So, angle 1+ angle 1 = 180° 2(angle 1) = 180° Angle 1 = 90° Angle 1, angle 2 = 90° Hence diagonals of a square are equal and bisect each other at right angle Hope you got it!!! ☺️☺️
