Web19 uur geleden · Asked by: Carel Lucas, Perth, Australia. Drift velocity, the average speed at which electrons travel in a conductor when subjected to an electric field, is about 1mm per second. It’s the electromagnetic wave rippling through the electrons that propagates at close to the speed of light. The dimensions of the wire and electrical properties like ... WebSound moves at a faster speed in water (1500 meters/sec) than in air (about 340 meters/sec) because the mechanical properties of water differ from air. Temperature also affects the speed of sound (e.g. sound travels faster in warm water than in cold water) and is very influential in some parts of the ocean.

WebUsing the definition of n , we can find the speed of light through lead: v lead = c / n lead = (2.99792458 x 10 8 m/s) / (2.6) = 1.2 x 10 8 m/s = 2.6 x 10 8 miles per hour Even slowed by lead, light travels at a speed of 260 million miles per hour! That's more than 10,000 times the speed of the orbiting space shuttle. A light-yearis the distance that light can travel in one year — about 6 trillion miles (10 trillion kilometers). It's one way that astronomers and physicists measure immense distances across our universe.
