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.
The most noticeable aspect of lightning and thunder is that the lightning is seen before the thunder is heard. This is a consequence of the speed of light being much greater than the speed of sound. The speed of sound in dry air is approximately 343 m/s (1,130 ft/s) or 1,236 km/h (768 mph) at 20 °C (68 °F; 293 K). [19]
Strategic planning is an organization's process of defining its strategy or direction, and making decisions on allocating its resources to attain strategic goals.. Furthermore, it may also extend to control mechanisms for guiding the implementation of the strategy.
Strategic planning's role is "to realise and to support strategies developed through the strategic thinking process and to integrate these back into the business". [14] Henry Mintzberg wrote in 1994 that strategic thinking is more about synthesis (i.e., "connecting the dots") than analysis (i.e., "finding the dots"). It is about "capturing what ...
A dimensionless quantity representing the ratio of the speed of an object moving through a fluid to the local speed of sound. Mach's principle The proposition that the existence of absolute rotation (the distinction of local inertial frames vs. rotating reference frames) is determined by the large-scale distribution of matter. machine
Motion of the medium itself. If the medium is moving, this movement may increase or decrease the absolute speed of the sound wave depending on the direction of the movement. For example, sound moving through wind will have its speed of propagation increased by the speed of the wind if the sound and wind are moving in the same direction. If the ...

Strategic leaders think strategically. Strategic thinking, as Batty and Quinn state, involves gathering, making connections, and filtering information or “form ideas and strategies that are focused, relevant, and sound.” (Beatty and Quinn, 2010, p. 5).
