Class 9 maths NCERT solutions- Heron’s formula

Class 9 maths NCERT solutions-Chapter 12 Heron’s formula To understand this formula better let us go through   Class 9 Maths solutions   Area of a triangle=√s(s-a)(s-b)(s-c) Exercise 1 Question 1 . A traffic signal board, indicating ‘SCHOOL AHEAD’ is an equilateral triangle with side     Find the area of the signal board, using Heron’s formula. If its perimeter is 180 cm, what will be the area of the signal board? MATHS Question Solution:-Perimeter=sum of all sides = 180=3a =side of a triangle 180/3=60cm =s=180/2=90 = using herons formula =√s (s-a)(s-b)(s-c) =√90(90-60)(90-60)(90-60) =√90*30*30*30 =√3*3*10*3*10*3*10*3*10 =3*3*10*10√3 =900√3cm² Question – Sides of a triangle are in the ratio of 12:17:25 and its perimeter is 540 cm. Find its area? Solution-  Let the ratio b x Perimeter= sum of all sides 540 =12x+17x+25x 540=54x X=540/54=10 Side a =12*10=120 Side b=17*10=170 Side c=25*10=250 S=a+b+c/2=540/2=270 cm Area of a triangle u

NCERT 12th physics notes - Electric Field

NCERT 12th physics notes - Electric Field Electric Field:  The region in which a charge experiences a force is called an electric field. Electric Field Strength:  Electric field strength at a point is vector quantity and is defined as the force experienced by unit positive charge placed at that point and whose direction is along direction of force. The electric field strength due to a point charge q at a distance r is E = q/4Π£ 0  r 2 The unit of Electric field strength is Newton/Coulomb. Electric Field Lines: The path along which a unit positive charge would move if it is free to do so. Properties of  Electric Field Lines: Electric field lines start at positive charge and end at negative charge. For an isolated single charge electric field lines start or end at infinity. Two electric field lines never intersect each other. In a charge free region electric field lines have no break or they are continuous. In a uniform electric field, electric field l

NCERT Chemistry Class 11 - Chemical Bonding

NCERT Chemistry Class 11 - Chemical Bonding  In this article, the following topic ‘Chemical Bonding’ from the unit  Chemical Bonding and Molecular Structure  of  Class 11 Chemistry  syllabus is discussed. Chemistry notes for class 11 :  A  Chemical bond  is an attraction between atoms or we can say elements (are the simplest type of matter containing only one kind of atom). A chemical bond enables the formation of a chemical compound. Hence a compound can be defined as a substance consisting of two or more different or same kind of elements that are bonded chemically. The chemical bonds hold the elements together and form temporary connections that are essential for life. The atoms can be connected together by strong bonds or by weak bonds. The chemical bonds are essential to the chemistry of a living organism as well as to the stability of the environment in which it lives. The elements combine in two general ways, and both involve the electrons (outermost or valence elec
