Flexibility (anatomy) For other uses of the term, see flexibility (disambiguation). Flexibility or limberness refers to the absolute range of movement in a joint or series of joints, and length in muscles that cross the joints to induce a bending movement or motion. Flexibility varies between individuals, particularly in terms of differences in muscle length of multi-joint muscles.
This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures. The formula to find the speed of sound in air is as follows: v = 331m/s + 0.6m/s/C * T. v is the speed of sound and T is the temperature of the air.One thing to keep in mind is that this formula finds the average speed of sound for any given temperature.The speed of sound is also affected by other factors such as humidity and air pressure. = 331m/s + 0.6m/s/C * T. v is the speed of sound and T is the temperature of the air.

The sound source is travelling at 1.4 times the speed of sound (Mach 1.4). Since the source is moving faster than the sound waves it creates, it leads the advancing wavefront. A sonic boom produced by an aircraft moving at M=2.92, calculated from the cone angle of 20 degrees. An observer hears nothing until the shock wave, on the edges of the cone, crosses their location.
