What else can I help you with?
Scientific notation of velocity of sound?
The velocity of sound in air at sea level at normal temperature and pressure is 3.4329 metres/second.
What is the longest distance you can run a string telephone?
The longest distance for a string telephone typically ranges from about 300 to 1,000 feet (approximately 100 to 300 meters), depending on the thickness and material of the string, as well as the tension and environmental conditions. Thicker, stronger strings can transmit sound better over longer distances, while factors such as wind and obstacles can hinder performance. However, sound quality will diminish as the distance increases.
What is the function of a megaphone?
megaphones are a device that loud-ens sound to a distance.
What formula is Vfx λ?
It looks a little like V = f x λ, which to me means velocity = frequency multiplied by wavelength. For example, with sound, you could have a frequency of 100Hz and a wavelength of 3.4m giving a velocity of 340m/s. Alternatively you could rearrange the equation if the velocity is know but the frequency or wavelength isn't
What is the distance sound travels in one hour?
About 767 miles, depending on the temperature and density of the air.
What should be the weight of the person projected with velocity of sound in vacuum and travellig millions of kilometer of distance?
The force (weight) between the person and earth diminishes with distance. eg double the distance, quarter the force.
Why does the pitch of a sound change as the source of the sound that moves past you?
Decreasing velocity, and distance.
What is the difference between sound in water and sound in air?
Velocity (distance-time), Magnitude (volume) and Density (echo/harmonic) signatures differ.
When was Velocity of Sound created?
Velocity of Sound was created on 2002-10-08.
What is the approximate velocity of the sound in air?
the velocity of sound in the air is 300m/s
Why thickness varies in percussion instruments?
Thickness affects sound.
Write an experiment to find the velocity of sound?
Write an experiment to find the velocity of sound?
How is an echo sounder used to determine the bathymetry of the ocean floor?
They send down a sound wave (whose velocity they know) and measure how much time it takes for it to return. Velocity=Distance/time Distance=Velocity*time They divide the distance by 2 (since the sonar wave has to return as well.) They make thousands of these measurements to make a map of the ocean floor based on these distances.
Give the effect of density on velocity of sound?
As density increases, the velocity of sound increases because there are more particles for the sound wave to travel through. Conversely, if the density decreases, the velocity of sound will also decrease because there are fewer particles for the sound wave to travel through.
Is Sound listen greater in solids or in air?
Sound velocity is greatest in solids, and the solid with the highest velocity of sound is metallic Beryllium.
How is wave velocity determined?
Wave velocity is determined by the medium through which the wave is traveling and the properties of the wave itself, such as frequency and wavelength. It can be calculated as the product of wavelength and frequency or by dividing the distance the wave travels by the time it takes to travel that distance. Additionally, the type of wave, such as sound or light, can also affect the velocity at which it travels through a medium.
How can you use echo to find out the speed of sound?
If you want to be as accurate as possible you will need to start with the temperature of the air. Once you know the temperature of the air you plug it in to this formula: V = 331 √1 + (T/273) V is the velocity of sound in air at temperature T in degrees Celsius. Now that you know how fast sound will travel through the air at the current temperature, measure the time it takes for the sound to be transmitted and the echo received. Take that number and plug it in to this formula: V = m/s or Velocity = meters/seconds From that we get: Distance = Velocity/time Divide the distance in half and you have your distance from the object which the echo bounced off of.
