Vote for very important questions in final exam
Of all chapters?...
Yes of all chapters social science and science
Yes
😂
Difference between loudness and intensity
Loudnes
1 subjective in nature
2 not complete physical quantity
3 depends upon sensitivity of ear
4 unit of measurement dB
Intensity
1 objective in nature
2 physical quantity
3 does not depend upon sensitivity of ear
4 W/m^2
Thank you sir understood all concepts now it's crystal clear 😊.
Please share the PDF 🙏
App se note le lo
7:45
Thanks
You are really a good teacher and can you kindly make a video on vernier calliper and screw gauge Icse 9
Thank you very much Sir.Very easy concept 🎉🎉🎉
sir on 1:23:59 you say that the difference between alex and wall is 17.3 then why in picture u wrote the distance from wall to alex 34.6 m tell me please why
yes sir why
Sir if particles don't move with wave then how is rare fraction and compression being created?
Please reply someone
Particles dont move with the wave but move forward and backward which is basically vibrating...so the particles vibrate and when they move forward (while vibrating) compression is created and then they come back to mean position so rarefaction is created; only the disturbance moves forward
(In the new ncert book page 128 propagation of sound)
Sir what is the difference between echo and reverberation.

Thank you, Sir.
Sir we want to know about haunted laboratory from you please 😢
Thankyou for this session ❤❤❤❤❤❤
14:39 sir domino’s nahi Doridos😂😂😂
Thank you sir it was very interesting and i understood the concepts very easily
Thank you sir for this session 😇😇
Understood all the concepts and Notes were being made during class:)
Please bring numerical sessions.

Sir aapne mosquito ke sound achi nikali by the the way your explanation is too good🎉🎉🎉🎉🎉🎉
1:12:50
yes
Best channel ever today I watched 4 sessions ❤❤
Yes sir very easy sound 😊
Thank you sir for this wonderful session!😃😇
Ok
sir you didn't cover rarefraction?
Sir par Jo rope hai jab vo aage jaega to peeche bhi to aaega
In rare case it happen
Thanks so much Sir ❤🎉😊
good teaching
Sir I have question can you explain me what types of sound?
Plzz bring important questions of all chapters of phy
sir i really felt very bad when you said the sentence "Elvish ke papa ka naam aa gaya dekho" you were my favorite physics mentor till but not now no more this is very shameful to disrespect someone with the reason nothing i don't like this behaviour😞😠😡 sorry if you felt bad but i gave my point of view🙏🙏
Good evening sir I undistand but I don't known how learn formula
Gr8 video ❤
He roast elvish yadav 😂😂😂
🐒
12:54 sir aap aur hmm UP vale h thela hi accha h hamare liye ....😅😅😅
Hamko bhi esae hi ek sir pha date hai
Sir
Paad ka bhi amplitude, frequency, pitch, wavelength, hota hai kya?
Sir what is crest and trough
NEW student 8E sakshi
Sir aap padahatei kam ho or time waste jada karte ho
( in my opinion)
We like to study like this only
fr bro wasted like half of the hour yapping nonsense
@@kitten_wonderMind your words
Then study from some other source
😂😂😂😂😂😂😂
Sir notes pdf
sir why are u struggling so much ?
Sound is a energy
How sound got trapped in a mobile phone and we can listen it later
