Vote for very important questions in final exam

[ROBOTICR.G]

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

[kalilgibran]

39:20 missed amplitude can be said as maximum displacement ON THE EITHER

[Dashgaming-pr]

7:40 sir is actually making the correct sound of everything through his mouth

[NaveedMinhas-ktep]

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

[rohitwalikar]

Thank you sir understood all concepts now it's crystal clear 😊.
Please share the PDF 🙏

[rajuchoudhary]

Sir if particles don't move with wave then how is rare fraction and compression being created?
Please reply someone

[KrishnaTiwari-bpzw]

Sir what is the difference between echo and reverberation.

[sauravshaw]

You are really a good teacher and can you kindly make a video on vernier calliper and screw gauge Icse 9

[jannatanwar-xoip]

Thank you very much Sir.Very easy concept 🎉🎉🎉

[susmakumari]

Sir aapne mosquito ke sound achi nikali by the the way your explanation is too good🎉🎉🎉🎉🎉🎉

[Bint_e_islam-s]

Best channel ever today I watched 4 sessions ❤❤

[shashilaxmiyadav]

12:54 sir aap aur hmm UP vale h thela hi accha h hamare liye ....😅😅😅

[Daksh-rsou]

sir you didn't cover rarefraction?

[NandanirawatRawat-wdcv]

Sir par Jo rope hai jab vo aage jaega to peeche bhi to aaega
