How do you find diplacement in position time graph?
Usually time is the independent variable on the horizontal (or X) axis. Position or displacement is the dependent variable (that is, it's a function of time) on the vertical (or Y) axis. For any point on the curve, there will be an associated value for time, t, and a corresponding value for displacement, s. In other words, you can determine an object's position -- or displacement from the origin -- for any time, t. Going further, you can determine an object's speed, too. For any two points on the curve, (t1, s1) and (t2, s2), the speed can be calculated using the following formula: Speed = (s2 - s1) / (t2 - t1)
What is the difference of speed of sound and speed of light?
The Basic difference between the sound waves and light is in their wave nature. Light waves are propagated as transverse waves. Sound waves are propagated as longitudinal waves. Let's do our own version of Einstein's famous thought experiments. You are on a train that has a very looong connected flatbed. I'm observing you from the ground. The train is moving at 60 mph to my right; you are in a car and driving from the front of the train toward the back, and you read 40 mph on your speedometer. As the amazing sight passes by, I measure your speed to be 20 mph, moving to my right-- from my frame of reference, your back-end is advancing. This is an entertaining if impractical way of seeing how two velocities differ. Sixty minus forty equals twenty. Now we are together on the ground. A train is going to pass us at the speed of sound (ok, we could make it an SST and pretend we're on a REALITY show). As it passes, our job is to measure the velocity of light coming toward us from a powerful source on its back. We are, in theory, slowing light down by the speed of sound. When we measure the velocity of the light, however, we will find that it is still exactly the speed of light, undiminished. If we forgot our protective gear, however, our ears will not be unchanged.
How fast is an object going if its speed and time graph is horizontal?
An object can only gain speed if there is a net force on it. If a net horizontal force acting on an object is large enough, or acts for a long enough time, the object can aquire a speed up to just under the speed of light, 3 x 10^8 m/s.
When does Sound travels fastest through matter when it is warm cold or not moving?
It depends... It's well-known that sound travels faster through denser (cold air has higher density then warm) media. So if you have a situation when sound travels through either cold or warm air. The speed of the sound will higher in the cold air. From other side if you have air which of course possesses certain temperature which is moving the sound speed will depend on both temperature and the vector of velocity (direction where it is blowing and and value how much it's blowing).
Which one of these is a scalar value?
Speed
What is the value of velocity of ultrasonic sound in water?
It should be about the same as the speed of normal sound. The speed of sound varies a bit, depending on the frequency, but usually that is not much.
How the value of speed of sound in air at 0c?
Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 0°C is c ≈ 331 + 0.6 × 0 = 331 m/s.
How do you find the square root of Speed of sound?
The speed of sound depends on the medium through which the sound waves travel - it is not a constant. So the first requirement would be to measure the speed of sound. Then simply take the square root of the numerical value and make sure the measurement units are "square-rooted" as well.
How is the absolute value of velocity speed?
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
Which is closest to the speed of sound in air in miles?
"Miles" is not a speed, it is a distance. A speed would be "miles per hour", for example. The speed of sound in air depends on several factors, especially on the temperature. A typical value is about 330 meters/second. I'll leave it up to you to convert this to the old-fashioned units.
How are Speed and acceleration related?
Speed is a scalar value meaning it has only a magnitude and velocity is a vector value meaning it has magnitude and a direction. The magnitude could be speed but if you say, "I'm going 3 meters per second," then you would be talking about speed but if you said, "I'm going 3 meters per second west," then you would be talking about velocity and a vector value. An acceleration is just a change in the magnitude and/or direction of a velocity.

How do you determine value of buffet clarinet?
Age, wear and tear, state of the pads and corks, cracks in the wood, the quality of sound, and the type-basic clarinet evaluation.
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.
