In music, the dynamics of a piece are the variation in loudness between notes or phrases.Dynamics are indicated by specific musical notation, often in some detail.However, dynamics markings require interpretation by the performer depending on the musical context: a specific marking may correspond to a different volume between pieces or even sections of one piece.
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air, is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
Dynamics in a piece should be interpreted relative to the other dynamics in the same piece. For example, pp should be executed very softly, but if ppp is found later in the piece, pp should be markedly louder than ppp. More than three p s (ppp) or three f s (fff) are uncommon. piano (p) Gently (i.e. played or sung softly) (see dynamics) piano ...
At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). An F/A-18 Hornet creating a vapor cone at transonic speed just before reaching the speed of sound. The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas.
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
Athletes' schedules are very well known, making them easier to target than other celebrities. The most well known of these burglaries was Burrow. His home was invaded on Dec. 10, while the Bengals ...
The first example of adaptive music is generally said to have been in Space Invaders by Taito in 1978. The game's simple background music, a four-note ostinato which repeats continuously throughout gameplay, increases in tempo as time goes on and the aliens descend upon the player. [3]
