<u>Answer:</u>
The correct answer option is C. E = kq / d^2
<u>Explanation:</u>
Electric field strength is a vector quantity which means it has both the magnitude and a direction.
It can be defined as the strength of electrical force per unit charge at any given point in the electric field and can be denoted by E.
Therefore, the formula for the electric field strength is:
E =
Answer:
It will float.
Explanation:
Hello.
In this case, given the width, length and height, we can compute the volume as follows:
Moreover, since the density is computed via the division of the mass by the volume:
We obtain:
In such a way, since the solid has a lower density than the water, we infer it will float.
Best regards.
A system that can be affected by the outside environment, by an exchange of matter or energy is an open physical system .
