Velocity-Time A car having initial velocity u is being subjected to a uniform acceleration a for a time period of t, after the time t, the final velocity of the car is v.Now we need to find the relation between v, u, a, t graphically.Initial velocity u at A = OAFinal ... Read More

Given: A 5m long ladder When Set Against The Wall Of A House Reaches A Height Of 4.8mTo do: Find how far is the foot of the ladder from the wallSolution:To solve this question, we will use Pythagoras theorem:$Hypotenuse^2 = Base^2+Height^2$ Here height = 4.8m, Hypotenuse = 5mWe ... Read More

Solution:Given a triangle with sides a, b and c and height hPerimeter of triangle = a + b + c  [sum of side lengths] Area of triangle = $\frac{1}{2} \times base \times height$ = $\frac{1}{2} \times b \times h$

Electricity:Electricity is a form of energy that is made available by the flow of electric current or charge flowing through a conductor.It is measured in joule(J).Electricity is the presence and flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its ... Read More

Synthetic fibres are those fibres that are made by humans through chemical synthesis, whereas natural fibres are those that are directly derived from living organisms. Synthetic fibres are created by a process known as polymerization. Examples- Rayon,   Nylon, Polyester,  etc.RAYONNYLONPOLYESTER1. Also known as Artificial Silk.1. The first synthetic made entirely from chemicals.1. Made from monomers called ...

Leaves are green because of the presence of the pigment called Chlorophyll.It absorbs light (red and blue) for energy; the unabsorbed green bounces away and is detected by our eyes and thus appearing green. But there are so many plants that may contain the different colours of leaves, because of ... Read More

A Rainbow is formed because of refraction. When the sunlight enters the droplets, the light bends as it enters into dense water from the air. Now the light gets reflected when it hits the inner surface of the droplet, breaking into components of several wavelengths(colors). When we see these colors ... Read More

Taproot System has a single primary root upon which small, lateral roots called root hairs are attached.For example-  Carrot, Mustard, Parsley, Beetroot, and all dicotyledons.

The magnetic force, one of the four fundamental forces of existence, is a result of the electromagnetic force which is induced by the acceleration of charges. Two objects with a charge having the same direction of motion have a magnetic force of attraction between them. 

Solution:Medians and Altitudes ln TrianglesMedian in a triangle is a line segment joining any one of its vertices with the midpoint of the corresponding opposite side of that vertex thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the ... Read More
