: loss of polarization; especially : loss of the difference in charge between the inside and outside of the plasma membrane of a muscle or nerve cell due to a change in permeability and migration of sodium ions to the interior â¦ partial depolarization of the ventricular tissue resulting from rapid conduction of the electrical impulse from the atrium ...
Cruise Speed (Normal)473 knots. Cruise Speed (Normal). Compared to the average Turbofan-powered Narrow-body Commercial Passenger Plane, which cruises at 458 knots (527 mph) to maximize range and can cruise at a maximum speed of 472 knots (543 mph), the Bombardier CRJ700: 1  Maximizes its range at a 11 knot (13 mph) lower speed (a 2.4% margin).
For the cartoon series, see Speed Bump. For speed changes in cinematography, see Speed ramping. Speed bumps (or speed breakers) are the common name for a family of traffic calming devices that use vertical deflection to slow motor-vehicle traffic in order to improve safety conditions. Variations include the speed hump (or speed ramp), speed cushion, and speed table. The use of vertical deflection devices is widespread around the world, and they are most commonly found where vehicle speeds are statutorily mandated to be low, usually 40 km/h (25 mph), or 8 to 16 km/h (5.0 to 9.9 mph) in car parks.
