GIVE SOLUTION

Ans 3: (Master Answer)

Class : Class 1

Ans 4:

Class : Class 7
The answer should be d because the rubber band is wider so it is striking back on the wooden piece on more area.

Ans 5:

Class : Class 5
The answer is D because A, B and C have thin rubber band and in D, the rubber band is Fat.

Ans 6:

Class : Class 7
D is wrong.

Class : Class 6
I will also agree with Ayushi

D D D IT IS D I WILL TELL YOU IT IS DI WILL TELL YOU THAT I AGREEWITH SOMEONE OVER HERE CALLED AYUSHI

Ans 10:

Class : Class 4
AS THINNER RUBBER WOULD BE PULLED TO A MAXIMUM DISTANCE HENCE MORE SOUND.

Ans 11:

Class : Class 7
The answer will be D because big rubber band so more sound as the wide rubber band is striking back on more part of the wooden piece.

Ans 12:

Class : Class 7
@Soumya Bajaj is right. @Vansh Garg, have you measured the sound's frequency in Decibels? The correct answer is A because the thinner the rubber band, the more it will strech and the more it will strech, the more sound it will produce.(Master Answer)
