Hii! friends welcome you all to the another interesting content it is actually a conversation between a teacher and a student regarding sunset I hope you all like this content. Raghu said -"Mam, yesterday I was on the terrace.I saw the sunset.It was so beautiful!The sun was absolutely red!" Mam replied- "I can think how beautiful it must have looked! But you will be surprised to know that sun itself has nothing to do with creating a beautiful sunset.One of the things that help create that effect is the dust in the air! You all know that the sun's white light is actually made up of all the colours of the rainbow.And that the atmosphere has molecules of air,dust and water vapour,they become scattered by these particles. At sunset, the sun is near the horizon. We see it through a much thicker layer of dust and air.All these particles change the direction of short-wave light from the sun.Only the longer wavelengths come through directly.Red and orange are longer wa...

Ram asked - "Mam,wolves,jackals and foxes are all dogs, aren't they?" Mam replied-"Yes,they are, They all belong to the same family.But wolves,jackals and foxes are called "wild dogs". When human beings realized the usefulness of dogs,they began to develop different breeds of dogs for special purposes.Dogs with long noses were bred to scent game.Keen- sighted fast dogs were bred to chase animals.Strong heavy dogs pulled carts.Other dogs were bred for guard work. Lets come to the point, What's the origin of the Dog? Answer: All living members of the dog family have descended from a wolf like creature called "TOMARCTUS". This ancient canine called the "Father of Dogs" roamed eart's forests about 15,000,000 years ago. Tomarctus itself descended from a small weasel- like creature called"miacis" which lived some 40,000,000 years ago. This creature was also the distant ancestor of the bears and racoons...

Praise The Lord Jesus Christ Mobile phones IN THE EARLY 1990s,THE MOBILE PHONE (Cell phone) was a rare luxury, but in recent years it has outsold almost every other electrical gadget- as a professional tool, domestic convenience,and even a fashion accessory. Mobile phones have also generally shrunk in size,due to improvements in rechargeable batteries,which now store more electricity for longer in a smaller package ,and to smaller , more efficient electronics that use less electricity.A "mobile" is basically a low- power radio receiver-transmitter,plus a tiny microphone to convert sounds into electrical signals, and a small speaker that does the reverse. When the mobile phone is activated,it sends out a radio signal that is answered by near by nearby mast transmitter- receivers. The phone locks onto the clearest signal and uses this while within range ( the range of each transmitter is known as a cell). The phone continuously mo...

Praise The Lord Jesus Christ The Earliest Road vehicle powered by an engine,the Cugnotsteam traction engine,was built in 1770. More practical steam carriages,such as the Bordino,were available in the early 19 th century,but they were heavy and cumbersome.Rest laws and introduction of railways,faster and able to carry more passengers,saw the decline of "cars"powered by steam.It was not until 1860 that the first practical power unit for road vehicles was developed, with the invention of the internal combustion engine by the Belgian Etienne Lenoir. By around 1890, Karl Benz and Gottlieb Daimler in Germany, and Albert de Dion and Armand Peugeot in France were building cars for sale to the Public. These early cars, despite being primitive, expensive,and produced in limited numbers, heralded the age of new Motor car.
