No. It is D. Science is actually testable. That is the purpose of the scientific method: to TEST a theory. For something to be considered science, you must be able to observe, ask questions, develop questions, and test them. Thefore, it is a process. Lastly, yes. Science is a body of knowledge. It's a subject field that covers many things and numerous sub areas.
Answer:
The intensity of the electric field is
![|E|=10654.37 \:N/C](https://tex.z-dn.net/?f=%7CE%7C%3D10654.37%20%5C%3AN%2FC)
Explanation:
The electric field equation is given by:
![|E|=k\frac{q}{d^{2}}](https://tex.z-dn.net/?f=%7CE%7C%3Dk%5Cfrac%7Bq%7D%7Bd%5E%7B2%7D%7D)
Where:
- k is the Coulomb constant
- q is the charge at 0.4100 m from the balloon
- d is the distance from the charge to the balloon
As we need to find the electric field at the location of the balloon, we just need the charge equal to 1.99*10⁻⁷ C.
Then, let's use the equation written above.
![|E|=(9*10^{9})\frac{1.99*10^{-7}}{0.41^{2}}](https://tex.z-dn.net/?f=%7CE%7C%3D%289%2A10%5E%7B9%7D%29%5Cfrac%7B1.99%2A10%5E%7B-7%7D%7D%7B0.41%5E%7B2%7D%7D)
![|E|=10654.37 \:N/C](https://tex.z-dn.net/?f=%7CE%7C%3D10654.37%20%5C%3AN%2FC)
I hope it helps you!
<h2>Answer: decibels
</h2>
The decibel
is the relation between two values: the pressure produced by a sound wave and a pressure taken as a reference. Resulting in a dimensionless value.
It should be noted that itself<u> is not a unit of measure</u>, since in reality the unit is bel
(which <u>is not part of the International System of Units</u>) in honor of Alexander Graham Bell.
However, given the amplitude of the measured elements in practice, its submultiple, the decibel, is used. That is, this quotient is a logarithmic expression, where
Answer: Point A is the answer for the potential energy. Point D is the answer for the kinetic energy.
