True

Vedclass · Answer

(A) The frequency of the sounding body is $f = 300 	ext{ Hz}$.Time taken to produce $30$ vibrations is calculated as $t = 	ext{number of vibrations} / 	ext{frequency} = 30 / 300 = 0.1 	ext{ s}$.Assuming the speed of sound in air is $v = 340 	ext{ m/s}$,the distance covered by the sound in $0.1 	ext{ s}$ is $d = v 	imes t = 340 	ext{ m/s} 	imes 0.1 	ext{ s} = 34 	ext{ m}$.Since the calculated distance matches the statement,the statement is True.

Write true or false for the following statement: Sound produced by a sounding body of frequency $300 \text{ Hz}$ covers $34 \text{ m}$ in the time the sounding body produces $30$ vibrations.
