Statement I: A tuning fork is considered...

Statement I: A tuning fork is considered as a source of an acoustic wave of a single frequency as marked on its body. Statement II: The tuning fork cannot produce any of its harmonics due to its special nature of construction.

A

Statement I is true, Statement II is true: Statement II is a correct explanation for statement I.

B

Statement I is true, Statement II is true, Statement II is NOT a correct explanation for Statement I.

C

Statement I is true, Statement II is false

D

Statement I is falce: Statement II is true

Text Solution

Verified by Experts

The correct Answer is:
A
The tuning fork does produce harmonics, but the intensities of the harmonics are too weak to be effective, due to its special ditribution of mass and the use of prongs.

A source of sound with adjustable frequency produces 2. beats per second with a tuning fork when its frequency is either 476 Hz or 480 Hz. What is the frequency of the tuning fork ?

Two tuning forks when sounded together give 8 beats per second. When tuning fork A is sounded with air column of length 37.5 cm closed at one end, resonance occurs in its fundamental mode. Tuning fork B gives resonance with air column of length 38.5 cm and is closed at one end in its fundamental mode. Find the frequencies of tuning forks.

    State an expression for the moment of inertia of a solid uniform disc rotating about an axis passing through its centre, perpendicular to its plane. Hence derive an expression for the moment of inertia and radius of gyration. (i) about a tangent in the plane of the disc, and (ii) about a tangent perpendicular to the plane of the disc. In a set, 21 tuning forks are arranged in a series of decresing frequencies. Each tuning fork produces 4 beats per second with the preceding fork. If the first fork is an octave of the last fork , find the frequencies of the first and tenth forks.

    Statement I: A body weighs less on a hill top than on earth's surface even though its mass remains unchanged. Statement II: The acceleration due to gravity of the earth decreases with height.

    STATEMENT-1 : Beats will be heard if a tuning fork is sounded along with a sonometer wire with the same fundamental frequency as the tuning fork because STATEMENT -2 : Beats are caused by alternate constructive and destructive interference between two sounds.
