The fastest thing in the whole universe is the speed of light in a vacuum. The speed is around 2.99 * 10^{8} . It is fastest in vacuum as vacuum does not contain any dust particles and is a hollow space so light travels faster. It also has a refractive index of 1 so it travels faster.

After vacuum light travels faster in air. Air has a refractive index of 1.0003.

After air, it travels faster in water. The speed is about 3/4 of its speed in a vacuum, or 225,000,000 meters per second. Speed slows in water because photons interact with atoms, which repeatedly absorb and re-emit them to the same direction. The refractive index of water is 1.33.

There are three long parallel wires arranged so that, in cross-section, they occupy the points of an equilateral triangle. Is th
Harrizon [31]

Answer:

Yes, there is such a way.

Explanation:

If currents flow in the same direction in two or more long parallel wires, there will be an attractive force between the wires. If the current flows in different directions, there will be a repulsive force between the wires. In this case, these three parallel wires, can be be made to carry current in the same direction, creating an attractive force between all three wires.

Note that it is not possible to have at the least one of them carry current in the opposite direction and still have an attractive current between them.
