Very, very strong. If you consider cosmic armor superman as superman, then he is the strongest. However, he is thought robot, a construct. he was c When lightning strikes, a noise is The speed at which highly trained humans tend to move such as Track runners with Usain Bolt's record being approx 12.5 m/s. The formula to compute Mach number in a supersonic compressible flow can be found from the Rayleigh supersonic pitot equation (above) using parameters for air: As can be seen, M appears on both sides of the equation, and for practical purposes a root-finding algorithm must be used for a numerical solution (the equation's solution is a root of a 7th-order polynomial in M2 and, though some of these may be solved explicitly, the AbelRuffini theorem guarantees that there exists no general form for the roots of these polynomials). [6] As modeled in the International Standard Atmosphere, dry air at mean sea level, standard temperature of 15C (59F), the speed of sound is 340.3 meters per second (1,116.5ft/s; 761.23mph; 661.49kn). Mach number (M or Ma) (/mk/; Czech: [max]) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. and the speed of sound varies with the thermodynamic temperature as: If the speed of sound is not known, Mach number may be determined by measuring the various air pressures (static and dynamic) and using the following formula that is derived from Bernoulli's equation for Mach numbers less than 1.0. This level of speed is beyond Supersonic level and achieved in real life by Fighter Jets such as the North American X-15. This seems to be the most accurate answer. 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 This page was last edited on 12 October 2022, at 08:43. 6.25 meters a second divided by 7.25 centimeters (0.0725 meters) equals 86.2, or in other words, someone moving at 6.25 meters a second could cover a distance of 7.25 centimeters 86 times in one second. What is the fastest thing in the universe? Even furthermore, even if you assume that Bradley actually was moving at the speed of a bullet in that scene, it's a hilarious outlier for the rest of his feats- he's not even actually faster than the mark one human eye can see, as the various Briggs soldiers are clearly capable of ._3K2ydhts9_ES4s9UpcXqBi{display:block;padding:0 16px;width:100%} Planes that move at Supersonic speeds must also be designed with aerodynamic heating in mind. At these speeds, the aerodynamic form of a vehicle takes a bit of a backseat to thermal control, as the sheer friction in the atmosphere can heat up a craft to extreme temperatures. Or put yet another way, our bullet will have covered the distance to the point where the target's head was originally inside 0.0262 seconds. Gotcha! [1][2], The Mach number is named after Moravian physicist and philosopher Ernst Mach,[3] and is a designation proposed by aeronautical engineer Jakob Ackeret in 1929. The first-ever Supersonic aircraft was the Bell X-1, an experimental rocket-powered plane. When lightning strikes, a bright flash of light is generated. Clancy, L.J. What speed is Mach 1 in miles per hour? approximately 760 miles per hour. How fast are the Mach speeds? Mach Speed is when an object moves faster than the speed of sound. For normal and dry conditions and temperature of 68 degrees F, this is 768 mph, 343 m/s, 1,125 ft/s, 667 knots, or 1,235 km/h. Parents are using Ford F-150 Lightning's front trunk for diaper changes. A person inside the aircraft will not hear this. The flash from the lighting that we see moves at the speed of light itself. However, the actual strike itself moves at only 1/3 of lighting, 270,00 I like this a lot. Any speed above Mach 10 is considered to be in the High-Hypersonic range. fast 2 of 4 adjective 1 as in rapid moving, proceeding, or acting with great speed the fast pace of construction resulted in our new house being done ahead of schedule Synonyms & Similar Words rapid quick galloping brisk swift speedy breakneck hot lightning hasty flying Assuming air to be an ideal gas, the formula to compute Mach number in a subsonic compressible flow is:[9]. Whirlwind is likely approaching above Mach 80 speeds depending on how you take the Ortho Twins Light-Speed reflexes into account. At high enough Mach numbers the temperature increases so much over the shock that ionization and dissociation of gas molecules behind the shock wave begin. However in the vacuum of space there are no air molecules to slow down the discharge so it can travel at its full speed.While the exact speed of lightning is still being studied one thing is for sure it is one of the fastest things in the natural world! I normally drive 80+ MPH and I've learned that at about 65 MPH, the battery energy burn is slow enough so that the Speedometer and the range estimators become almost accurate. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. [1][2] Mach is the ratio of an object's speed to the speed of sound. He aims to create content that educates, persuades, entertains and inspires. Lightning travels at the speed of light, about 186,000 miles per second. ._1sDtEhccxFpHDn2RUhxmSq{font-family:Noto Sans,Arial,sans-serif;font-size:14px;font-weight:400;line-height:18px;display:-ms-flexbox;display:flex;-ms-flex-flow:row nowrap;flex-flow:row nowrap}._1d4NeAxWOiy0JPz7aXRI64{color:var(--newCommunityTheme-metaText)}.icon._3tMM22A0evCEmrIk-8z4zO{margin:-2px 8px 0 0} Press question mark to learn the rest of the keyboard shortcuts. Thats INCREDIBLE. When the speed of sound is known, the Mach number at which an aircraft is flying can be calculated by. In terms of the various Mach numbers, they fall into a few different categories. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. As a general rule though, at an air temperature of 0 degrees Celsius (32 degrees Fahrenheit), the Just use the VSBW speed hierarchy, IMO is the easiest to understand: Subsonic (Mach 0.1-0.5) (34.3-171.5 m/s or 76.7-383.6 mph), Subsonic+ (Mach 0.5-0.9) (171.5-308.7 m/s), Transonic (Mach 0.9-1.1) (308.7-377.3 m/s), | Info | PM | Stats | Opt-out | v.4.4.6 |. Anything that doesn't move or which movements are too slow to perceive such as bacterias. All Rights Reserved. Assuming air to be an ideal gas, the formula to compute Mach number in a subsonic compressible flow is found from Bernoulli's equation for M < 1 (above):[9]. .s5ap8yh1b4ZfwxvHizW3f{color:var(--newCommunityTheme-metaText);padding-top:5px}.s5ap8yh1b4ZfwxvHizW3f._19JhaP1slDQqu2XgT3vVS0{color:#ea0027} Because that flight only lasted a few seconds, the record for the longest sustained flight above Mach 5 belongs to the Boeing X-51, another unmanned experimental aircraft, which in 2013 flew for over three minutes at Mach 5.1 (about 3,400 mph). Emily Jaehnert regularly drives an all-electric Ford F-150 Lightning pickup truck more than 400 Continuous shockwaves will be generated by planes moving at Supersonic speeds, necessitating their slick design. We can use this knowledge to approximately determine how far away a lightning strike has occurred. If anything, Killua would have to had moved close to light-speeds but would need actual light-speeds to stop the dart before it could even pierce his skull at all. Due to the rarity of feats at this level it is pointless to create specific classes to rank them, thus they are determined to be a TFTC case. Researchers are looking into the applications for new Super and Hypersonic crafts, and this includes a possible revival of Supersonic passenger travel. Fast, Free Shipping on orders over $99. Stay indoors and avoid travel if possible. FTL or Faster Than Light is the speed level that is literally being faster than Light Speed. The speed of sound varies depending on At Hypersonic speeds, some of a planes energy will actually excite the chemical bonds that make up molecules of oxygen and nitrogen in the air. So the regime of flight from Mcrit up to Mach 1.3 is called the transonic range. Shouldn't reactions be measured in time, not speed anyway? This is a well documented field, and the average maximum survivable g-force is about 16g (157m/s) sustained for 1 minute. It has a distinguishing blunt nosecone created to deal with the harsh atmospheric drag and compression flying at those speeds entails. Lightening is the discharge of static electricity through the atmosphere. As such it travels close to the speed of light. I am not sure of the exac Mach 15 is about 5104.35 meters per second. ._1EPynDYoibfs7nDggdH7Gq{margin-bottom:8px;position:relative}._1EPynDYoibfs7nDggdH7Gq._3-0c12FCnHoLz34dQVveax{max-height:63px;overflow:hidden}._1zPvgKHteTOub9dKkvrOl4{font-family:Noto Sans,Arial,sans-serif;font-size:14px;line-height:21px;font-weight:400;word-wrap:break-word}._1dp4_svQVkkuV143AIEKsf{-ms-flex-align:baseline;align-items:baseline;background-color:var(--newCommunityTheme-body);bottom:-2px;display:-ms-flexbox;display:flex;-ms-flex-flow:row nowrap;flex-flow:row nowrap;padding-left:2px;position:absolute;right:-8px}._5VBcBVybCfosCzMJlXzC3{font-family:Noto Sans,Arial,sans-serif;font-size:14px;font-weight:400;line-height:21px;color:var(--newCommunityTheme-bodyText)}._3YNtuKT-Is6XUBvdluRTyI{position:relative;background-color:0;color:var(--newCommunityTheme-metaText);fill:var(--newCommunityTheme-metaText);border:0;padding:0 8px}._3YNtuKT-Is6XUBvdluRTyI:before{content:"";position:absolute;top:0;left:0;width:100%;height:100%;border-radius:9999px;background:var(--newCommunityTheme-metaText);opacity:0}._3YNtuKT-Is6XUBvdluRTyI:hover:before{opacity:.08}._3YNtuKT-Is6XUBvdluRTyI:focus{outline:none}._3YNtuKT-Is6XUBvdluRTyI:focus:before{opacity:.16}._3YNtuKT-Is6XUBvdluRTyI._2Z_0gYdq8Wr3FulRLZXC3e:before,._3YNtuKT-Is6XUBvdluRTyI:active:before{opacity:.24}._3YNtuKT-Is6XUBvdluRTyI:disabled,._3YNtuKT-Is6XUBvdluRTyI[data-disabled],._3YNtuKT-Is6XUBvdluRTyI[disabled]{cursor:not-allowed;filter:grayscale(1);background:none;color:var(--newCommunityTheme-metaTextAlpha50);fill:var(--newCommunityTheme-metaTextAlpha50)}._2ZTVnRPqdyKo1dA7Q7i4EL{transition:all .1s linear 0s}.k51Bu_pyEfHQF6AAhaKfS{transition:none}._2qi_L6gKnhyJ0ZxPmwbDFK{transition:all .1s linear 0s;display:block;background-color:var(--newCommunityTheme-field);border-radius:4px;padding:8px;margin-bottom:12px;margin-top:8px;border:1px solid var(--newCommunityTheme-canvas);cursor:pointer}._2qi_L6gKnhyJ0ZxPmwbDFK:focus{outline:none}._2qi_L6gKnhyJ0ZxPmwbDFK:hover{border:1px solid var(--newCommunityTheme-button)}._2qi_L6gKnhyJ0ZxPmwbDFK._3GG6tRGPPJiejLqt2AZfh4{transition:none;border:1px solid var(--newCommunityTheme-button)}.IzSmZckfdQu5YP9qCsdWO{cursor:pointer;transition:all .1s linear 0s}.IzSmZckfdQu5YP9qCsdWO ._1EPynDYoibfs7nDggdH7Gq{border:1px solid transparent;border-radius:4px;transition:all .1s linear 0s}.IzSmZckfdQu5YP9qCsdWO:hover ._1EPynDYoibfs7nDggdH7Gq{border:1px solid var(--newCommunityTheme-button);padding:4px}._1YvJWALkJ8iKZxUU53TeNO{font-size:12px;font-weight:700;line-height:16px;color:var(--newCommunityTheme-button)}._3adDzm8E3q64yWtEcs5XU7{display:-ms-flexbox;display:flex}._3adDzm8E3q64yWtEcs5XU7 ._3jyKpErOrdUDMh0RFq5V6f{-ms-flex:100%;flex:100%}._3adDzm8E3q64yWtEcs5XU7 .dqhlvajEe-qyxij0jNsi0{color:var(--newCommunityTheme-button)}._3adDzm8E3q64yWtEcs5XU7 ._12nHw-MGuz_r1dQx5YPM2v,._3adDzm8E3q64yWtEcs5XU7 .dqhlvajEe-qyxij0jNsi0{font-size:12px;font-weight:700;line-height:16px;cursor:pointer;-ms-flex-item-align:end;align-self:flex-end;-webkit-user-select:none;-ms-user-select:none;user-select:none}._3adDzm8E3q64yWtEcs5XU7 ._12nHw-MGuz_r1dQx5YPM2v{color:var(--newCommunityTheme-button);margin-right:8px;color:var(--newCommunityTheme-errorText)}._3zTJ9t4vNwm1NrIaZ35NS6{font-family:Noto Sans,Arial,sans-serif;font-size:14px;line-height:21px;font-weight:400;word-wrap:break-word;width:100%;padding:0;border:none;background-color:transparent;resize:none;outline:none;cursor:pointer;color:var(--newRedditTheme-bodyText)}._2JIiUcAdp9rIhjEbIjcuQ-{resize:none;cursor:auto}._2I2LpaEhGCzQ9inJMwliNO,._42Nh7O6pFcqnA6OZd3bOK{display:inline-block;margin-left:4px;vertical-align:middle}._42Nh7O6pFcqnA6OZd3bOK{fill:var(--newCommunityTheme-button);color:var(--newCommunityTheme-button);height:16px;width:16px;margin-bottom:2px} However, once the flow becomes supersonic, the relationship of flow area and speed is reversed: expanding the channel actually increases the speed. The speed of sound in air varies with the air density and humidity, but a typical value is 343 meters per second. Maybe it's better to measure how fast the character is moving but its easier to just say "x timer" because its more commonly used. 1 Decillion xSoL to any higher finite speed or anything under infinite speed. The conservation of mass flow rate leads one to expect that contracting the flow channel would increase the flow speed (i.e. (Fig.1b). See also: N. Rott: Jakob Ackert and the History of the Mach Number. 1. F-150 Lightning Electric Truck Promises Great Efficiency And Power. In dry air, at 0 degrees Celsius, the speed of sound is about 331.3 meters per second. The obvious result is that in order to accelerate a flow to supersonic, one needs a convergent-divergent nozzle, where the converging section accelerates the flow to sonic speeds, and the diverging section continues the acceleration. Photo: NASA.gov, Public Domain. Meanwhile cloud-to-ground lightning (lightning that connects a cloud to the ground) can travel at speeds of up to 60 miles per second.So how does lightning travel so fast?Lightning is caused by an electrical discharge that occurs when the air around a thunderstorm cloud becomes charged with static electricity. lightning =/= light thats a biiiiiig misconception. After a while, the whole cloud fills up with electrical charges.
