Velocity is a vector quantity that measures speed (and also includes direction).

55 mph is a speed.

55mph North is a velocity.

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.



What is the effect of velocity of sound in velocity?

Speed of sound has no effect on the particle velocity. Call velocity of sound better speed of sound. Call sound velocity better particle velocity. Velocity of sound is not sound velocity.


What is the difference between speed of sound and velocity of sound?

Speed is the rate of change of distance with time. Velocity is a measure of both speed and direction of a moving object. Velocity is the rate of change of displacement with time. Speed is a distance an object goes, velocity is measurment of speed AND direction.


Effect of velocity of medium on velocity of sound?

Speed of sound has no effect on the particle velocity. Call velocity of sound better speed of sound. Call sound velocity better particle velocity. Velocity of sound is not sound velocity.


Velocity in sound waves?

Velocity of sound is not sound velocity. Speed of sound has no effect on the particle velocity. Call velocity of sound better speed of sound. Call sound velocity better particle velocity.


What velocity of sound in air?

Usually we talk about speed of sound. Speed is the rate of change of distance with time. Velocity is a measure of both speed and direction of a moving object. Velocity is the rate of change of displacement with time. Speed is a distance an object goes, velocity is measurment of speed AND direction. Speed of sound at 20 degrees Celsius (68 degrees Fahrenheit) is 343 meters per second.


Explain how the velocity of sound in gas depends upon density and elasticity?

The velocity of sound in a gas depends upon density and elasticity since the speed of a wave is defined as the distance that a point on a wave.


What is the difference between sound in water and sound in air?

Velocity (distance-time), Magnitude (volume) and Density (echo/harmonic) signatures differ.


How do scientists use sound waves to figure out the shape 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 of medium increase velocity of sound decreases.


Do all frequencies of sound travel with the same velocity?

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.


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.



What is sound wave velocity?

Sound waves are longitudinal waves in air. Velocity of sound waves in air at NTP = 332 m/s.


How do you find distance using an echo?

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.
