Light in a vacuum is generally held to travel at an absolute speed, but light traveling through any material can be slowed down. The amount that a material slows down light is called its refractive index. Light bends when coming into contact with particles, which results in a decrease in sp...
You can expect a 150cc moped to reach an advanced speed of roughly70 mph,which is a little faster compared to the speed of a 100cc or 125cc one. In general, a moped with a 150cc engine is more powerful than those with smaller engines. It becomes even more suitable for long travels ...
Since the ring gear is spinning, the planets have to spin, which causes the sun gear and generator to spin. As the car accelerates, the generator spins at whatever speed it needs to in order for the engine to remain off. Once you reach about 40 mph (64 km/h), the gasoline engine ...
GPS, or the Global Positioning System, is a global navigation satellite system that provides location, velocity and time synchronization. GPS is everywhere. You can find GPS systems in your car, your smartphone and your watch. GPS helps you get where you are going, from point A to point ...
(63 to 118 km/h), it is considered a tropical storm and it gets a name from a list put out by the World Meteorological Organization. Once those sustained winds reach 74 to 95 mph (119 to 153 km/h), that storm becomes a Category 1 hurricane. According to the Saffir-Simpson scale, ...
Just as water squeezed through a narrow pipe accelerates dramatically into a fast jet (think of what happens in a water pistol), the tapering design of the exhaust nozzle helps to accelerate the gases to a speed of over 2100 km/h (1300 mph). So the hot air leaving the engine at the ...
At speeds below five kilometres per hour (3mph), the ocean will be great regardless of whether you're going in a direction or not. When winds are over 30km/h (20mph), it will get complicated. Even when they come from off the shore. The morning is often the best time to surf ...
Crossing the Little Belt (Lillebælt in Danish) from Jutland (mainland Denmark) to Funen, the island on which Odense is located. 5. Copenhagen to Stockholm by X2000 These Swedish 200km/h (125mph) tilting trains link Copenhagen & Stockholm in just a few hours, centre to centre. They cr...
How does a plug-in hybrid work? A hybrid car is like two cars in one: it has a conventional gasoline (petrol) engine for fast freeway driving and an electric motor for more economic, pollution-free travel (or idling). In different designs, the wheels are driven by the engine, the mot...
