Because of the meteorological significance of these observations and their implication in supersonic aerodynamics, we have carried out a new determination of the velocity of sound in air at pressures down to 5 mm. mercury.doi:10.1038/172363a0CARO, D. E...
Ifvmis the velocity of sound in moist air,vdis the velocity of sound in dry air, under identical conditions of pressure and temperature View Solution The frequency of a rod is 200 HZ. If the velocity of sound in air is340ms−1, the wavelength of the sound produced is ...
THE following simple way of arriving at the velocity of sound in air occurred to me lately :-Standing on a straight Staircase between two blank walls (brick, and papered), which I find to be 32½ inches apart, I clap my hands. The effect from each clap is a brief musical sound, ...
Welcome to express the viewpoint or to input you to need to turn やりたい puts the text which the topic translates![translate] aV s is the velocity of sound in the air between the transmitter and the receiver v s是声速在天空中在发射机和接收器之间[translate]...
Determinations by capable investigators of the velocity of sound in dry air at 0°C range from 330.6 to 331.9 m/sec. Miller's value (331.36±0.08) m/sec . is probably the best for low frequency (explosive) sounds. Part of this range of values may be due to dispersion. The CO 2 and...
At room temperature (27∘C) the velocity of sound in air is 330 m/s. the increase in velocity of sound when temperature is increased by 1∘C is A2 m/s B1 m/s C10 m/s D0.55 m/sSubmit The velocity of sound in air at 27∘C is 330 m/s. the velocity of sound when the ...
A PREVIOUS communicationdescribed an oscillographic method for measuring the velocity of sound in air. Further experiments have been made during the past four years, with the aid of a grant from the Research Committee of King's College, Newcastle-upon-Tyne, and during 1947 a series of 940 ...
The velocity of sound in air is approximately 343 meters per second. (空气中的声速大约是每秒343米。) The velocity of the bullet was measured to determine the effectiveness of the new rifle. (子弹的速度被测量以确定新步枪的有效性。) The velocity of the wind was so strong that it uprooted ...

The velocity of sound in water is more than four times that in air.声音在水中的速度是在空气中的速度的4倍多。词义辨析:speed,rate,velocity,pace 这些名词均含“速度、速率”之意。speed普通用词,指单位时间内行进的固定速度或速率,也指可能达到的最高速度。rate作“速度”讲时,与speed...
