The fastest thing in the whole universe is the speed of light in a vacuum. The speed is around 2.99 * . 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.
The volume of the rock, given the data is 14 mL (Option A)
<h3>Data obtained from the question</h3>From the question given above, the following data were obtained:
- Volume of water = 20 mL
- Volume of water + rock = 34 mL
- Volume of rock =?
The volume of the rock can be obtained by calculating the displacement of the water when the rock was added. this can be obtained as follow:
Displacement of water = (Volume of water + rock) - (volume of water)
Displacement of water = 34 - 20
Displacement of water = 14 mL
Thus, the volume of the rock is 14 mL
