Julius Robert Mayer discovered the Law of Conservation of Energy.
To find a solution to this problem it is necessary to apply the concepts related to the Reynolds number and its definitions on the type of fluid.
A Reynolds number less than 2000 considers the laminar fluid, while a Reynolds number greater than 4000 is considered a turbulent fluid. (The intermediate between the two values would be a transient fluid)
The mathematical equation that defines the Reynolds number is given by

Where
Density
V= Velocity
D= Diameter
Viscosity
Our values are given as





The velocity can be find through the Discharge equation,
Q = VA
Where
V = Velocity
A = Area
Replacing,


Replacing at the Reynolds equation,



Since Reynolds' number is greater than 4000, then we consider this a turbulent fluid.
Answer:
C. Lighting is made of atoms
Explanation:
Everything is made of atoms that are, in turn, made out of charged particles. All charged particles come in one of two types: positive and negative (or plus and minus). The minus particles are the electrons, and the plus particles are the much heavier protons which are buried deep in the nucleus.
Based on the information in the question, a light year is the distance traveled light in one year. Then if the light from the star Centauri takes 4.2 years to reach the earth, then its distance from earth is 4.2 light years.
Answer:

Explanation:
The relative velocity can be calculated by means of the difference between vector B minus vector A.
