Answer:
<h3>1.502</h3>
Explanation:
Using the snell's law refraction to solve this problem;
According to the law, the ratio of the sine of incidence to the sine of refraction is a constant for any given pair of medium. Mathematically;
n is the refractive index of benzene
i is the angle of incidence = 43°
r is the angle of refraction = 27°
Get the index of refraction of benzene;
Hence the index of refraction of benzene is 1.502
We will apply Newton's first law to define the balance on a body. A particle is considered to be in equilibrium when the result of several forces acting on it is equal to zero. In this way a body is in static equilibrium when it is at rest and no force acts on it and is considered in dynamic equilibrium when the body travels at constant speed without any force acting on it.
Therefore, according to these definitions both bodies are in a type of equilibrium: Dynamic and static.
