Answer:
The water from head of 20m or above is brought in open or closed conduit. Traditionally wooden blades are used as turbine on which water jets are strike upon, jets rotates the bigger wheel mounted on smaller wheel. There is continuos feed of grains in between grinds into finer particles.
<u>Answer</u>
The distance must be one-third the original distance.
<u>Explanation</u>
Gravitational force is the force of attraction between two bodies of given masses. It is calculated by the formula;
Gravitational force = Gm₁m₂/r²
This means, for the gravitational force to remain unchanged, both numerator and denominator has to change by equal value.
The numerator changed by (1/3×1/3 = 1/9).
So, r² must change by the same value which is 1/9.
If r² ⇒ 1/9, then
r ⇒ √1/9
⇒ 1/3
So, this means, for the gravitational force to remain as 200, The distance must be one-third the original distance.

Explanation:
From the question we are told that
The refractive index of the core is
The refractive index of the cladding is
Generally according to Snell's law
Where is the largest angle a largest angle a ray will make with respect to the interface of the fiber and experience total internal reflection
Given from the question the the largest angle is 5°
Generally the refraction index of the cladding is mathematically represented as
