A sound wave is a longitudinal wave
The refractive index of a material is a dimensionless number that describes how fast light travels through the material. It is defined as n={\frac {c}{v}}, where c is the speed of light in vacuum and v is the phase velocity of light in the medium.
the ratio of the velocity of light in a vacuum to its velocity in a specified medium.
Force is used to put things in motion you can’t have motion without force!
Even if it just pushing a piece of paper you still use force to put the paper in motion!
This is because, nuclear forces are short range forces.
The protons and neutrons are collectively called nucleons and they are found in the nucleus of an atom. These nucleons are held together by a strong attractive force called the nuclear force.
When atoms combine, they are held together by forces determined by electrons in the outermost shell. The influence of the nuclear force does not extend beyond the nucleus because they are short range forces.
Hence, we not consider the strong nuclear force when we describe the forces between atoms.

Answer:
So if we need to cover 1000 meters. And we go at a speed of 4.3 m/s. That means that every 4.3 meters we cover is 1 second. So we divide both amd get
1000/4.3 = 232.56 is approx the answer. Also the meters cancel out because
m/(m/s) = m*s/m, cancels out giving s as a unit.
<h2><u>
Therefore the answer is 232.56 seconds</u></h2>
