What is the speed of dark?

Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. via

How did Einstein know the speed of light was constant?

It can be derived from Maxwell's equations that the speed at which electromagnetic waves travel is: c=(ϵ0μ0)−1/2. Since light is an electromagnetic wave, that means that the speed of light is equal to the speed of the electromagnetic waves. via

Does time stop at the speed of light?

The simple answer is, "Yes, it is possible to stop time. All you need to do is travel at light speed." The practice is, admittedly, a bit more difficult. Addressing this issue requires a more thorough exposition on Special Relativity, the first of Einstein's two Relativity Theories. via

Why is light the fastest speed possible?

Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so. via

Why do ships use knots?

Boats and planes, which often travel longer distances affected by the earth's curvature, use knots. Knots are a more accurate way of predicting how a boat (or a plane) traverses the face of the earth. That's why nautical charts include and depend on longitude and latitude measurements. via

Why do planes use knots?

Boats & Planes calculate speed in knots because it is equal to one nautical mile. Nautical miles are used because they are equal to a specific distance measured around the Earth. Since the Earth is circular, the nautical mile allows for the curvature of the Earth and the distance that can be traveled in one minute. via

Why are nautical miles different?

Nautical Miles

A nautical mile is slightly longer than a mile on land, equaling 1.1508 land-measured (or statute) miles. The nautical mile is based on the Earth's longitude and latitude coordinates, with one nautical mile equaling one minute of latitude. via

What's the speed of sound in space?

A: Sound can't actually travel in space. Sound is created when particles vibrate in a pattern, creating waves. Since space is a vacuum, there are almost zero particles in space. via

Why do we hear more clearly in a room with curtains?

We hear more clearly in a room with curtains than in a room without curtains because sound is absorbed by the curtains. A sound created in a room without will persist by repeated reflection from the walls until it is reduced to a value where it is no longer audible. via

Does sound travel faster when cold?

Because sound moves faster in warm air than colder air, the wave bends away from the warm air and back toward the ground. That's why sound is able to travel farther in chilly weather. via

How far can your little brother get before his gun runs out of paint if he can travel at 2.5 m/s and if fired continuously the gun will run out of paint in 16 seconds?

How fast is 90m in 45 seconds?

So here in this question, time is given to us that is equal to 45 seconds, and this is is given us 90 m and we have to calculate velocity as we know, velocity is distance for unit time, Distance is 90 m and time is 45 seconds. So velocity will come out to be 2m/s. via

What is the speed of a plane that travels 400 meters in 10 seconds?

divide 50 by 10 to convert to metres per second = 5 m/s. Then multiply by 3.6 (3600 seconds in an hour divided by 1000) to convert to kilometres per hour =18 m/s. To convert to mph divide by 1.609 =11.18 mph. via
