The speed of a beam of light will appear the same to all observers.
<h3>Speed of light:</h3>
The exact distance that light travels in a vacuum in a second is 299,792,458 meters (983,571,056 feet). This is roughly 186,282 miles per second, or "c," the symbol for light speed in mathematics.
According to Einstein's theory of special relativity, an object (such as a single photon of light) cannot appear to move faster than the speed of light. This physical rule is not broken by Nemiroff's experiment since the laser pointer emits a stream of photons rather than a single photon.
Nothing can move faster than light in a vacuum, according to one of physics' most revered rules. However, in a recent experiment, this speed restriction was broken when a laser pulse traveled at more than 300 times the speed of light.

The mechanism that is responsible for the formation of snowflakes is the nucleation of ice crystals.
<h3>What is a Snowflake?</h3>
This is defined as a piece of snow which falls from the sky as a result of an extremely cold climate condition and is common in the arctic regions of the world.
Snow flakes are formed when ice crystals stick together to form the flakes which usually has a dust or pollen being formed around the area being talked about.
This is also regarded as a type of precipitation such as rain etc and is therefore the most appropriate choice.

If the small and big stones are dropped from the roof of a house simultaneously, both stones will reach the ground at the same time due to the effect of gravity.
No matter how much is the mass of an object the gravity will attract it to the earth center with an acceleration of 32,17 ft/s2
<h3>What is gravity?</h3>
In physics, gravity is the force of attraction that the earth exerts on all bodies possessing mass by pulling them toward its center.

Answer:
Explanation:
We shall apply gas law formula to get the solution .
P₁ V₁ / T₁ = P₂ V₂ / T₂
P₁ = 10⁵ + 18 x 10³ x 9.8 where 10⁵ Pa is atmospheric pressure at surface
= 1.764 x 10⁵ + 10⁵
= 2.764 x 10⁵
2.764 x 10⁵ x 3 / ( 273 + 9 ) = 10⁵ x V₂ / ( 273 + 22 )
V₂ = 8.67 cm³
