Are Earphones harmful?

When any sound wave enters our ear, it creates vibrations in our eardrum. These vibrations then travel through tiny bones and eventually get transmitted to cochlea. Cochlea is a fluid-filled chamber with tiny hair cells. The vibrations move the fluid as well as the hair cells, allowing us to hear. 
Now, as earphones are very close to our eardrums, continuous loud music causes extreme movement of the hair cells, thus decreasing their sensitivity over time, eventually leading to hearing loss. However, we can prevent this by the following ways. Firstly, we can hear better quality music at a lower volume level with noise-cancelling earphones as they remove unwanted background sounds. Secondly, some experts recommend the 60 by 60 rule. One should listen to music at 60% volume for a maximum of 60 minutes. Thirdly, over-the-ear headphones are recommended as they are further away from our eardrums

Why do the Indian telecom operators offer their services with 28 days validity, not 30 days?😡😡

Here telecom operator are very clever, b ecause telecom operators want to earn money of 13 months instead of 12 months. Let do the calculation and find out why telecom operators are offering 28 days validity. Each month they get 2 days more, therefore in a year they get additional 24 days. There are 7 month which has 31 days so they get additional 7 days.Now in case of February  ,it has only 28 days not 30. So the total number of days they get are=24+7-2=29 days. So if you recharge 12 times then more 29 days are left in a year.🤔🤔 Means for another 29 days you have to recharge from that telecom operator.😫😫 So you have to recharge 13 times in a year instead of 12 times in a year. So telecom operators provide 28 days validity only. First one telecom operator started and then another telecom operators also understood this concept and they also applied 28 days validity both in data packs and voice packs.😱😱😱

How Hydroelectric power produced?

Water has been used to power man-made mechanisms for hundreds of years, mostly in food production in the form of a mill wheel to grind corn. However, using the kinetic energy of water probably became a reality earlier than you thought. In 1878, inventor Lord Armstrong lit his home in Northumberland using only the power of a nearby waterfall. It’s not until the latter half of the 20th Century that we began to take advantage of the massive potential of hydroelectric power. Intriguingly, both the dirty and environmentally unfriendly coal power plants and clean, green hydro-power use almost identical technology to generate power. Central to a coal-fi red plant is a turbine: coal is burned to produce heat energy, which is used to boil water into steam, which then drives a turbine. Hydroelectric power removes the coal and steam elements and instead, fl owing water turns the blades of each turbine.  By damming a river next to a drop in elevation and releasing a co...
