Sound intensity is defined as the sound power per unit area. Although the units for sound intensity are technically watts per meter squared, it is much more common for it to be referred to as decibels, dB. It is one tenth of a bel on the logarithmic intensity scale. A decibel is a ratio of the observed amplitude, or intensity level to a reference, which is 0 dB. Hence, the S.I. unit of sound intensity is decibels. Reference: Byjus
Frist question answer vector quantity sir 😅 but your asked question super sir 😊si unit three question super but I gain new knowledge sir in your video 📸❤❤
The answer to Q9 is WRONG. The watt per square metre, symbol W/m2, is the SI coherent derived unit of heat flux density, and irradiance The correct answer is A. The decibel (dB) is a logarithmic unit used to measure sound level.
Yes, as everyone said displacement is vector quantity. But none of them has understand what you have pinned..vector quantity as both magnitude and direction But scalar quantity has only magnitude. By this displacement has both magnitude and direction. By depending up on the object its may act as magnitude. So answer is displacement

Q:no1. Sorry Displacement is a vector quantity with a magnitude and a direction.
Absolutly correct and I have noticed this thing ..

This video is very helpful for me thanks ❤
SI unit of sound intensity is decibel Db.
Thank you sir ♂️.
I appreciate and I will do the rest
Thanks for your classes
Sir or bhej di ji ae question entance exam k liye pau
Thanks sir 🙂
Elastic,potential, energy
Sir displacement is a vector quantity distance is scaler quantity
Path follow by body in particular direction is called displacement..
Yes I have already pined check my first comment.
Solar,pover ❤❤❤❤❤
Frist question answer vector quantity sir 😅 but your asked question super sir 😊si unit three question super but I gain new knowledge sir in your video 📸❤❤
Thank you sir ❤❤
👍🏻✅
Iow, density 🎉
Displacement vector quantity ha
displacement is a vector quantitiy both magnitude &direction❤
Q9 correct because intensity is defined as power Carried by a wave in area so the unit of power is wat and area is m2 so the unit of is w/m2

Sir G the diffraction is correct
Q1 is wrong displacement is a vector quantity
displacement is avector
Displacement is a vector quality both magnitude and direction
Right
Thankyou sir🥰
The answer to Q9 is WRONG.
The watt per square metre, symbol W/m2, is the SI coherent derived unit of heat flux density, and irradiance
The correct answer is A. The decibel (dB) is a logarithmic unit used to measure sound level.

Distance is scalar quantity displacement is vector quantity
Good bro
Wolume is a scalar quantity
Sir, SI unit of sound intensity is dB (Decibel)
We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels.
Displacement is a vector quantity
Displacement is a vector quantity.
Sir 23 question solved correctly ❤
1st question is wrong because all quantity are vector
Exactly but already explained in ist coment
2:14 sound ki SI unit Decibel hogi aap galti se w/m² kardiye hai
sound ka decibel hai but sound intensity ka watt per square meter hi hai
Distance is scaler quantity but displacement is vector 😮😮😮teacher
Tq sir physics+ chemistry ye chapter wise question kra dijiye yese hi entrance exam ke liye
👍🏻
Yes😂
Si unit of sound intensity is db
You are right mai yehi kahne wali thi😊😊😊

First question machiga chadhuvadi sir
Distance is scalar quantity
Q :9 is wrong it is si unit of sound intensity formula is watt per square meter (w/m2) and si unit of sound intensity is Decible (dB)
Dhyan se pdho udhr sound intensity ka hi sir ne watt per square meter btaya hai na ki sound ka..... Bina dekhe bolne se phle socha krr...

@ExphubBadal yes
Displacement isn't a scalar its vector quantity😅
Distance hona chahiye tha
Q .29 wrong right ans is 6
Displacement is not scalar quantity
Displacement is a vector quantity. Not scalar
I have pined check the first coment
Yes, as everyone said displacement is vector quantity. But none of them has understand what you have pinned..vector quantity as both magnitude and direction
But scalar quantity has only magnitude.
By this displacement has both magnitude and direction.
By depending up on the object its may act as magnitude.
So answer is displacement
