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 old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
So you normally came in at 600 yards [550 m; 1,800 ft] and would open fire on your B-17. And your closing speed was still high and since you had to break away at 200 metres [220 yd; 660 ft] to avoid a collision, you only had two seconds firing time. Now, in two seconds, you can't sight. You can fire randomly and hope for the best.
F5. 261–318 mph. Incredible. The Fujita scale (F-Scale; / fuˈdʒiːtə /), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and engineers after a ground or ...
The Mach number (M or Ma), often only Mach, (/ mɑːk /; German: [max]) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. [1][2] It is named after the Austrian physicist and philosopher Ernst Mach. where: M is the local Mach number, u is the local flow velocity ...
The winds, Feerick added, would be “unbelievable.”. “You would have debris flying through the air at 150mph; anything that hits you could kill you instantly. You probably wouldn’t be able ...
Tornado intensity is the measure of wind speeds and potential risk produced by a tornado. Intensity can be measured by in situ or remote sensing measurements, but since these are impractical for wide-scale use, intensity is usually inferred by proxies, such as damage. The Fujita scale, Enhanced Fujita scale, and the International Fujita scale ...
The world best time for a "football 40" is 4.17 by Deion Sanders, while the extrapolated best for an Olympic-level athlete (including reacting to a starting gun) is 4.24 by Maurice Greeneat the 2001 World Championships in Athletics. [249][250]Under conventional football timing on a turf field in 2017, Christian Colemanreportedly ran a 4.12.
