Mr. Prashant sir i follow all of ur vedios..They benefit me a lot... 1. Simple easy & understable language 2. Good quality material 3 . Use of graphics..maps is best 4. Short & informative content 5. Valid & neutral explanation I wish u all the best... Congratulations for ur efforts ..All d best👍 Thank you
Maine iss topic se related kaee video dekha aur utna easy se ni smjh paya jitna study IQ pr Maine smjha ,thanks sir for giving clearing my all the doubts
36 seconds...4k views...this is power of PRASHANT DHAVAN😘😘😘...WE want a separate playlist of all your video.... . Who want Hit like so they will listen 😘
sir me aapki video interest or jigeasa ke lia sunta hu .sir yah video to sar kr upr se nikal gea ..thanks sir vese aapke video me Etna interest aata ki ek me bad ek video sunte jao....thanks sir
E=mc^2 E=nhv So Mc^2=nhv M=nhv/c^2 Here n=number of bambared photons on one side of kibble balance,h=6.62×10^-34 C=3×10^8 V=frequency of photons Other side of balance =one kilo of existing wieght Finally we will have number of photons which will be used as reference to create new one in future that can never be changed
In India the definition of kilo gram and meter varies everywhere when you go to buy grossery In baniya ki dukan me. Sab ke paas apna khud ka invent kiya hua weights bar milega. Aur meter ka definition kapde ki duakan me , ek haath felado matlab ek meter .. agree or not
Bohr's atomic model states Electrons can't revolve around the nucleus in any path of their choice but there are only some selected path where an electron can revolve. These are the path where angular momentum of an electron equals to integral multiple of h/2π where h is Planck Constant. mvr=nh/2π m is mass of electron v=velocity r=radius of the curve in which electron revolves assuming nucleus to be a point at the center. n= integer (1, 2,3....) so, h=mvr × 2π/n= Planck's constant Unit of h=unit of mvr i.e, kg × m/s × m = kgm²/s As we know standard definition of meter and second, kg can be calculated.
Hi Prashant, though, i am not preparing for any of the exams, i love to watch your informative videos. Thanks for sharing amazing videos. Really appreciate your efforts, Keep up the good job. 😊👍
The change in the mass can only be due to mass decay no other factor can be that significant bcz it's been kept under vacuum sealed isothermal containment where no reaction can take place.
बचपन मे मीटर किलोग्राम की defination रटनी पडती थी और मुझे illogical लगती थी ऐसे कैसे defintion दी जा सकती है.. अब बच्चों को नयी परिभाषा याद करना ज्यादा अच्छा रहेगा
Hi Prashant, would you please make a video on how the time was defined, how the day measured in 24hrs and a month is defined in 30,31 days. How the year was defined of 365/366 days. How the calendar was made, how it all started, can we change the calendar now?
Great , you are fabulous prashant sir, any type of knowledge in a world you distribute this knowledge for we know and learn and develop our knowledge boundary .👏👏👏👏👏👏👏👏
Our life depends on others so much that at the root of our existence is a fundamental need for love. That is why it is good to cultivate an authentic sense of responsibility and concern for the welfare of others.
Now Weight is no more a scalar quantity ....& After 20 may it becomes a Vector because of implementation of Planck constant which is Universal Constant in definition of weight..... Hence, students of class 9th & 10th will not study the difference between Mass & Weight
No, I don't think so because like pressure is scalar being the ratio of two vectors. And if we consider mass as vector then in which direction. And the relation between mass and weights is still valid because we just changed the defination gravitational force still effect in mass.
@Chetan Prakash I don't consider Mass as a Vector quantity it still a Scalar , actually I am a little bit confused in the quantity of weight ....it is still a Vector ...but before this implementation we use Spring Balance to measure the weight....but now after introduction of Planck Constant E= hv which elaborates that Planck constant (denoted h, also called Planck's constant) is a physical constant that is the quantum of electromagnetic action, which relates the energy carried by a photon to its frequency. A photon's energy is equal to its frequency multiplied by the Planck constant. The Planck constant is of fundamental importance in quantum mechanics, and in metrology it is the basis for the definition of the kilogram......we replace the instrument Spring Balance.....& Either use Planck Constant or wait for new instrument based on Planck's one👍
North pole m gravity ki wajah s weight jada hota h..aur bhumadhya ki taraf weight kam hota. ... To yaha s ek kg iron north pole l gye to uska weight jada hoga kya? Value jada hogi kya?
jo Electronic measuring instruments hai dukano par unme KG ka weight kaise kam ho sakta hai? kya KG ki value change hone par uska weight bhi different ho jayega?..
But speed of light, and planks constant consists of the same units which were then measured using those alloys..... Means when we say, light can travel 2.99* 10^8 m/s, that m was already measured keeping the length of rod as reference. And now you are defining the meter using the speculated speed of light which is already imperfect..... Isn't it paradoxical?
