words with long a sound

Let a long coiled spiral spring be suspended horizontally from a wooden frame using a number of threads. Ordinarily, the turns of the spring will be equidistant. On giving a sharp tap to one end of the spring, a few turns will come closer together. This state of compression moves forward..

sound is given by the formula The velocity of sound in iron was determined by two French investigators by striking one end of a long series of connected iron pipes with a hammer and measuring the time interval between the two sounds heard at the other end..

For a given source, P is a constant. i.e., the intensity of sound varies inversely as the square of the distance from the source and the point where its effect is considered. Intensity of sound involves purely objective considerations with respect to the source of sound..

A narrow and long hollow tube of glass or a metal, open at both ends is taken. It is partially immersed vertically in a tall jar containing water. The length of the tube above the water level in the jar serves as an air column whose natural frequency depends on its length and the diameter..

Hearing - The immediate and acute effect of noise pollution is impairment of hearing. Damage to the eardrum can be caused by impulsive loud sounds or by prolonged exposure to noise. Long exposure to loud noise may result in hearing loss which may become permane..

Since the denominator in the RHS of the above equation is less than 1, f 1 > f 2 . Thus, the increase in the apparent frequency is greater when the source approaches a stationary observer than, when the observer approaches a stationary source. In other words, Doppler effect in sou..

These monkeys thus have three kinds of signal-soundings: 1) The 'leopard-signal', 2) The 'eagle-signal', and 3) The 'snake-signal', which are motivated by three different situations. And they have three kinds of adequate reactions to these signals. They may have even more signal-sound..

Reverberation - The persistence of audible sound even after the source has ceased emitting sound is called reverberation. If the reverberation of a sound pulse persists so long as to prolong the sound while several successive pulses are produced, th..
