Velocity is a vector quantity that measures speed (and also includes direction).
55 mph is a speed.
55mph North is a velocity.
The velocity of sound in air at sea level at normal temperature and pressure is 3.4329 metres/second.
megaphones are a device that loud-ens sound to a distance.
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
About 767 miles, depending on the temperature and density of the air.
Speed = (wavelength) x (frequency) = (2 x 6) = 12 meters per second.That's the wave's speed. "Velocity" is something different, not just a wordto use when you mean "speed" but you want to sound more technical.
The force (weight) between the person and earth diminishes with distance. eg double the distance, quarter the force.
Decreasing velocity, and distance.
Velocity (distance-time), Magnitude (volume) and Density (echo/harmonic) signatures differ.
Thickness affects sound.
Velocity of sound in Acetone is about 1174 m/s
the velocity of sound in the air is 300m/s
the velocity of sound in the air is 300m/s
Velocity of Sound was created on 2002-10-08.
Write an experiment to find the velocity of sound?
Yes, they do. The frequency of a sound doesn't effect the speed at which it moves; i.e. approx 330meters per second (through air). For example; a sound with a frequency of 600Hz has the same velocity as a sound with frequency 300Hz, the difference being that the sound at 300Hz would have half as many wavelengths in the same distance from source as the sound at 600Hz.
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.
as density of medium increase velocity of sound decreases.
