Speed of Sound

The 3200 bit of AMD 64 3200 means that the processor is equivalent to a Pentium 4 3.2 GHz processor. The reason that they do this is to stop you getting confused as AMD processors run a lower clock rates but they are a lot more effcient than Intels in processing instructions, so they put the equivalent speed of a Pentium that can match the performance of the AMD chip.

These sounds have got a specific name. They are known as Ultrasounds. We can hear them, but the problem is that they cause the eardrum to vibrate too much and hence they are incomprehensible.

They are called ultra sonic. They travel faster than sound

Simply put, sounds are made through vibrations in the air. We can translate these vibrations into sound because of our ear drums.

"Breaking the sound barrier" means that you go faster than the speed of sound. The speed of sound varies depending on various circumstances; in air, it is typically about 340 meters per second.

Sound waves are longitudinal in nature, and they require a medium for propagation.

Sound is a mechanical wave. It requires a medium for propagation. Since the particles in a solid are close together, the sound energy is propagated way faster in solids rather than liquids and gases whose particles are not as close.

The energy used to power a computer is Electrical Energy.

Volume in singing refers to the loudness or intensity of the sound produced by a singer. It is important for a singer to be able to control their volume to effectively convey emotions and communicate with their audience. Singers can vary their volume by adjusting their breath support, resonance, and vocal technique.

Mostly on temperature and composition of the medium it is propagating through. You may not think temperature, but it does play a major role. There is also a weak dependence on frequency (pitch) and pressure.

The propagation of sound depends on molecules moving and pushing against other molecules. Different substances have different resistances to molecules pushing on other molecules. Density also affects how much the molecules resist being pushed around - so the speed of sound depends on that. Temperature affects density and also the inter-molecular forces that influence how the molecules resist being pushed around and how freely they will move and push against other molecules (thus propagating the sound wave). The dependency on pressure comes into play particularly in gases when the gas gets compressed enough to have a noticeable deviation from ideal gas behavior. The dependence on frequency has to do with the fact that gases are made up of molecules, which respond differently to different frequencies depending on the harmonic frequencies of the vibrations of the atoms in the molecules.

Note that in solids, the speed of sound can also be affected by the structure of the solid - traveling at a different speed when moving "with the grain" than they do when moving "across the grain".

A cycle in a sound wave is the time taken for one complete vibration.

Light is almost a million times faster.

When calculating the speed of sound do you multiply or divide the distance by the frequency? If you mean the formula for the speed of sound c then the wavelength lamda is multiplied by the frequency f. c = lambda x f f = c / lambda lambda = c / f

The speed of air at 20 degrees Celsius is 343 meters per second. The speed of light is 299 792 458 meters per second.

Pressure does not make any change in the speed of sound

But temperature affects it. Velocity is proportional to the square root of kelvin temperature

Humidity also affects the speed of sound. Higher the humidity more the speed

doppler log

This is a low temperature. It travels in less than 340ms-1.

"Sound that is an imitation of another sound" can be an echo, a recording, or an imitation.

Yes that is the case.

All submarines have several methods by which they can determine a general navigational position or a precise navigational fix:

1. GPS Satellite Network or SatNav fix

2. Electronic Gyroscope

3. Dead Reckoning plot

4. Radio Bearing

5. Visual Aid (close to shore, e.g., lighthouse, landmark, etc.)

6. Sunline (Sextant can be used when surfaced, or attached to Periscope while submerged)

7. Radar

For target range calculation, it depends on whether or not it's a visual and Sonar target, just visual, or just on Sonar. Visually, range markers on the Periscope indicate estimated range, however unless circumstances warrant, that range will always be verified and compared with Sonar range.

Sonar ranges are determined over time by tracking the target through induced turns (zigs), either by the submarine or the target. Either way, the change in direction adds another leg to the target tracking solution; eventually an estimated range based on known, sound trigonometric calculations weil be formulated, either by computer (normal) or by hand (backup). The tracking solution takes into account several known variables given by Sonar:

1. Estimated target speed (RPM) and type (e.g., Merchant, Warship, Trawler, etc.)

2. Sonar bearing

3. Closing or Opening Range (target getting closer or moving away)

Sonar's given target tracking information is based on the current sound profile for the given operating area the submarine is in, as all information is based on the current speed of sound in water, which can change.

In the end, target speed, bearing, and course are the key factors in determining range prior to a torpedo shot; however, in most circumstances, the shooting submarine will check a target's range with all other information plotted with active Sonar echo ranging (usually only 1 or 2 pings to verify range). If the range matches the plot, the information is fed into the torpedo guidance computer prior to shooting.

Basically, pressure is just a way to quantify the overall effect of many particles colliding with the side of a container. Each collision of particle and container transfers a force into the container. When particles have a higher speed they cause more acceleration and therefore more force into the container. Since pressure is the force per unit area, when the force increases, so does the pressure. So basically, the higher the particle speed, the higher the pressure.

The peak of a sound wave is the instant at which the particles in the conducting medium are displaced farthest from their rest position. Note that the peak ... or any other point in the wave ... moves through the medium, at the speed of . . . . . wait for it . . . . . sound !
