torque - ML^2T^-2
Surface tension - ML^0T^-2
Charge - M^0L^0 IT

[divyanshi_chhillar]

1:01:43
answer:- a=1/2
b=1/2
so, formula v=k underoot g into r
sorry sir laptop me signs nhi the type krna pda😁

[divyanshi_chhillar]

answer:- a= M-1 T^2
b= M-1 T^1

Torque-ML²T^-2
Surface tension-M¹L⁰T^-2
Charge-M⁰L⁰A¹T¹

[Rahul_swargiary_]

28:5 homework
1. Torque= Force × perpendicular distance
=MLT-2×L
=[ML²T-2]
2.Surface = Force/Length
=MLT-2/L
=[MT-2]
3. charge= Current × Time
=A×T
=[AT]

[Aesthetic_canvas]

28:00 hw
Torque=[ ML^2T^-2 ]
Surface tension= [ML^0T^-2]
Charge = [ AT]
Convert 1N to dyne
n2 = 10^5
1:23:16 hw
Answer= 9× 10^6
New student sir literally you explained each and every concept so well☺️✨thank you sir!!! 🙏🏻

[devikrishna]

Thank you so much your efforts for us were worth it ....

[unknownperson-odtt]

27:56 torque = [ MLT-2]
Surface tension= [ MT-2 ]
Charge = [ AT ]

Dimensions Formula Limitation
No angle information
No value information

[ajaykarohta]

basically sir is having a great teaching skills he made thing easy to understand and thus we are happy or
sir = great teaching (let equation 1)
students = happy (let equation 2)
by adding equation 1 and 2
sir + students = great teaching and

[HimanshuRt]

28:33 torque - MLT-².
