What happens to the speed of sound in air when the pressure increases at a constant temperature

The speed of sound in air is 60 m/s. How far from the centre of a storm is an observer who hears a thunder clap 4s after the flash of the lightning?

Which of the following media allow(s) the transmission of sound waves through them? I. Air II. Liquid III. Solid

A sound note of frequency 250 Hz and a wavelength 1.3 m is produced at a point near a hill. If the echo of the sound is received 1 second later at that point, how far away is the hill from the point?

A listener can detect the instrument from which a note is being sounded because different instruments produce the same note with different

A sonometer's fundamental note is 50Hz, what is the new frequency when the tension is four times the original?

Two tuning forks of frequencies 6Hz and 4Hz respectively are sounded together. The beat frequency is

Which of the following factors does not affect the speed of sound?

An explosion occurs at an altitude of 312 m above the ground. If the air temperature is -10.00°C, how long does it take the sound to reach the ground? [velocity of sound at \(0^oC\) = 331 ms-1]

The pitch of a musical note is determined by the frequency of the sound wave that it produces. If two instruments have the same frequency, which of the following factors will most affect the difference in their pitches?

The periodic rise and fall in the intensity of sound produced whn two notes of nearly equal frequencies are sounded together is called?

A hunter fires a gun at a point 408 m away from a cliff. If he hears an echo 2.4 s later, determine the speed of the sound wave

A tuning fork having a frequency of 312 Hz emits a wave which has a wavelength of 1.10 m. Calculate the velocity of sound

The main factor which affects the speed of sound wave is the?

A source of sound produces waves in air of wavelength 1.65m. If the speed of sound in air is 330ms\(^{-1}\), the period of vibration in air is?
