Velocity in sound waves?
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.
What is the number of cycles per second of sound waves?
what is being asked for in this question is "frequency(f)", but in order to answer to answer this question, there is need to know the velocity of this sound wave and its wave length. since there are non of these mentioned in the question, i will give my own values, let the velocity be 330m/s which is the speed of sound in air and let the wave length be 30m. therefore f=velocity/wave length: which gives f=330m per second/30m = 11 hertz
Can anyone give definition for Doppler frequency?
It is not Doppler frequency. It's Doppler effect. The APPARENT change in the frequency of the source as there is a relative motion between the source and the observer is defined as Doppler effect. The expression for frequency (apparent) is given fapparent = [(C - Vo + Vm)/(C-Vs+Vm)] x freal The condition to be kept in mind is that the source is on the left side and the observer on the right side along positive X axis. Vm - velocity of the medium and the medium is moving along positive X axis. Vo - the velocity of the observer Vs - the velocity of the source C - velocity of the wave either sound or light But in case of light Vm is not needed as the medium movement will not affect the velocity of the wave in any way.
Why is speed vital part of expressing velocity?
"Speed" is the name we give to the magnitude of velocity ... the 'size' of the velocity, without its direction.
What is the Doppler effect. How might the Doppler effect be used to measure velocity?
Doppler effect is a effect of a sound that comes from moving object. Sound travels at the speed of 343 meters per second in dry air at 20 degree Celsius. Suppose the object is coming you with high speed the sound waves will get compressed. If the object goes away from you with high speed the sound waves will get diluted. You must have noticed a vehicle with siren coming to you and going away from you. The pitch of the sound is different in both the cases. The computer can give you the real time calculation of the speed. speed can be calculated by the computer in very short duration of the span. May be second or two. This phenomena is widely used to locate the speed of the moving object. In the medical field, it is very valuable tool. The speed of blood flow can be transformed into different colors. Like in color Doppler ultrasound examinations.

Can you give me a sentence with the word tyndall effect?
The Tyndall effect is used commercially to determine the size and density of particles in aerosols.

What is density Give density of water?
Density=mass/volume density of water in the whole earth is 1
Find the velocity in meters per second of a baseball thrown 38m from third base in 1.7s?
A baseball travels under the effect of the force of gravity so its velocity is constantly changing. It is, therefore, not possible to give a sensible answer to the question.
How do you make a physics project?
What ever element of knowledge you have, just use it. If you already learn about mass and acceleration you might try measure effect of fluid density medium to acceleration upon dropping mass in the medium. You can vary shape and mass to see effect. If you know momentum transfer, you might want to correlate bouncing of ball on different medium and measuring sound of impact to see if sound is energy loss from impact. You just need to give out curiosity with existing knowledge you posess.
Does constant speed give you constant velocity?
No. The speed can be consant but direction can change and thus the velocity changes.
What does displacement divided by time give you?
The Average Velocity on a position time graph or a velocity time graph.
