<span> It is inversely proportional to the square of the distance of the listener from the source
so B is the right option
hope this helps</span>
Answer:
A. it is near the inside surface of the balloon
Explanation:
As we can see in the question shown above, the electric charge is distributed on the surface of a spherical conductive envelope, a balloon. This means that the surface of the balloon becomes automatically energized and the regions closest to that surface experience greater electrical force. With this we can affirm that the center of the balloon has a lesser electrical force, since it is the region farthest from the surface.
Based on this, we can say that the particle that is inside the balloon will be subjected to a greater electrical force when it is close to the inner surface of the balloon.
The answer is 117.6 J
The potential energy of
the object is actually its stored energy:
<span>E =
m · g · h
E - the potential energy of the object,
m - the mass of the object,
g - acceleration due to gravity,
h - the height of the object.
m = 4 kg
g = 9.8 m/s</span>²
h = 3 m
E = 4 * 9.8 * 3 = 117.6 J
