For the electric field is measured for points at distances r,Electric field is mathematically given as
E=19.9*10^{-5}c/m^3
<h3>What is the
Electric field?</h3>
Generally, the equation for the electric field uniform charged is mathematically given as
Therefore
E=lr/3E0=3Ee0/r
Therefore
E=3*6*10^4*8.85*10^{-12}
E=19.9*10^{-5}c/m^3
In conclusion, E=19.9*10^{-5}c/m^3
E=19.9*10^{-5}c/m^3

Complete question attached below
In order to find the solid, you would want the object in which sound travels the fastest
In this case, since in object C, the speed of sound is the fastest, it is the most likely to be a solid
So object C is most likely to be a solid
la separación mecánica de un sólido de grano grueso, insoluble, en un líquido; consiste en verter cuidadosamente el líquido, después de que se ha sedimentado el sólido. Por este proceso se separan dos líquidos miscibles, de diferente densidad, por ejemplola separación de un sólido disuelto en un líquido, por calentamiento, hasta que hierve y se transforma en vapor. Como no todas las sustancias se evaporan con la misma rapidez, el sólido disuelto se obtiene en forma pura, agua y aceite.
Answering the question, three examples of ways that physicists model the physical world include:
- Diagrams
- Equations
- Computer simulations
Computer simulations refer to the reproduction of behavior of a system with the use of a computer to simulate the results of a mathematical model that is linked with the system.
<h2>Further Explanation</h2>
Computer simulations are a tool that is very useful for mathematical modeling in various natural systems in physics.
Physicists write the rule of our universe using equations. Equations are an aspect of one of the models used by physicists to explain a particular situation.
Physicists use a diagram to convey information. It is a symbolic representation of information with the use of visualization techniques. Diagram provides other means for people to better understand information and process its importance.
Physics predictions about the physical world mainly depend on numerical stimulation, mathematics and empirical observations and Physicists models the physical world based on invariances and laws which are built on mathematical models.
The purpose of physics is to explain or describe everything around us. It described virtually everything around us accurately by deploring the law of physics.
However, physics is considered a natural science because it is based on mathematical analysis which is geared towards findings qualitative physical law for the physical world.

Answer:
<u>1000N</u>
Explanation:
It takes 200N to expand 15cm of one string.
For 5 strings, force required =
200 x 5 = <u>1000N</u>
