if Standing closer to the train, why we are pushing towards the train????

if Standing closer to the train, we are pushing towards the train, so why does it happen? Before understanding this concept, it is very important to know the two laws of physics.

1. Pascal's law: - Pascal law tells us that if the Velocity of air is the same around us, So we will get equal pressure from all around.

2. Bernoulli's principle: - Bernoulli's theory states that if the velocity increases, the pressure decreases and if pressure increases Velocity decreases, that is, pressure and Velocity are inversely proportional of each other.

Now if you are standing on the platform and no train is going from there. It means the air is the same around you, then you will get the same pressure from all sides. But as soon as the train passes near you, the air on the side of the moving train changes its velocity Because the wind on that side will increase due to moving train. we have just read that if the velocity increases, the pressure decreases. Then the pressure of air on the side of the train will decrease and due to low pressure, We will be pushing towards the train. By the way, this pressure is low. But still, we should always stand behind the yellow line of the platform.

Why 1 dollar is not equal to 1 rupee (1 डॉलर 1 रुपये के बराबर क्यों नहीं होता है?)

दोस्तों इंडियन होने के नाते आपकी भी मेरी तरह एक Wish होगी कि काश एक डॉलर एक रुपए के बराबर हो जाए क्योंकि सच में अगर ऐसा होता है तो चीजें हमारे लिए बहुत सस्ती हो जाएंगी जैसे ऐसे 700 rs का i Phone और बहुत सी ब्रांडेड चीजें जो बहुत-बहुत सस्ती लेकिन ऐसा क्यों नहीं होता है कि $1 एक रुपए के बराबर हो जाए तो चलिए इसे देखते हैं इसके कुछ प्रमुख कारण हैं व्यापार :- दोस्तों जैसे हमें पता है कि भारत एक विकसित नहीं बल्कि विकासशील देश है जो विकसित होने की तरफ हैं लेकिन विकसित नहीं है तो हमें बहुत सी चीजों के लिए दूसरे देशों पर निर्भर रहना पड़ता है| और हम दूसरे देशों के साथ व्यापार करते हैं जैसे कि चीनी चाय और बहुत सारी ऐसी चीज है जो हम दूसरे देशों के साथ व्यापार करते हैं अब अगर एक रुपए की कीमत $1 के बराबर कर देते हैं तो जो भी देश हम से खरीदते हैं तो उनके लिए सामान बहुत महंगा हो जाएगा जैसे की चाय का व्यापार भारत और श्रीलंका दोनों करते हैं उदाहरण के लिए अगर 1 किलो चाय की कीमत 100 रुपए है तो जो दूसरे देश चाय खरीदते हैं उसे भारत से चाय खरीदने के लिए $100 देने पड़ेंगे क्यों...

Rupee !! History Of Rupee????

Rupa is a Sanskrit word. Which means that the silver coin, which we make a knock-on peat. The bar-tar system was run in Indian Valley Civilization. Bar-tar system means to take another thing in exchange for anything. As if we have more rice and we also need wheat, then we can take some wheat for the second instead of some of our rice. But in the year 1540, the Sher Shah launched Rupai for the first time. In which 1 rupee means 1 silver coin which was equal to 178 wheat grains But after the first World War, silver and gold prices increased, then the British government denominated the Indian rupee. In which now 1 rupee means 16 aana, which was equal to 64 paise. all these copper were made of nickel. But after 1961 only the rupee was mad...
