What else can I help you with?
Is the speed of sound a constant?
yes
What is the different between constant velocity and constant speed?
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.
How did pressure effects the sound when temperature is constant?
The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
Does sound velocity change based upon sound frequency?
No, sound velocity does not change based on sound frequency in a uniform medium. In a medium with a constant temperature and pressure, the speed of sound remains constant regardless of the frequency of the sound waves.
Why is the speed of sound constant despite changing frequencies?
Speed of sound in a medium depends only on the properties on the medium.
If a ferris wheel is rotating at constant speed is it moving at a constant velocity?
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
Why doesn't pressure affect the speed of sound?
Pressure doesn't affect the speed of sound because the static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature and because the ratio p_ / ρ is always constant whether on a high mountain or even on sea level altitude. Therefore, the speed of sound stays constant and is only dependent on the changing temperature.
Newton's work showed that speed of light and sound were constant true or false?
False. Newton's work did not involve the speed of light and sound. The concept of constant speed of light was later formulated by Einstein in his theory of relativity. The speed of sound can vary depending on the medium it travels through.
What process is primarily responsible for the increase of speed and sound on a rail road track?
The speed of sound depends on the medium. There is no particular process that will simply increase the speed of sound.
What is the effect of pressure o the speed of sound?
The air pressure has no effect. The static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature. The ratio p_ / ρ is always constant, on a high mountain or even on sea level altitude. That means, the ratio p_ / ρ is always constant on a high mountain, and even at "sea level". The static atmospheric pressure p_ and the density of air ρ go always together. The ratio stays constant. When calculating the speed of sound, forget the atmospheric pressure, but look accurately at the very important temperature. The speed of sound varies with altitude (height) only because of the changing temperature there.
When the source of sound is moving its speed increases true or false?
False. The speed of sound in air is constant, around 343 meters per second. When the source of sound is moving, it can affect the frequency and intensity of the sound, but not the speed at which the sound travels.
What is the speed of light on Mars?
Sound always travels at the same speed. The speed of sound varies by medium and temperature. Aerospaceweb seems to conclude that the speed of sound on the surface of Mars is roughly 550 mph.
