Answer:
Explanation:
Force between two charges is given by the following expression
F =
Q₁ and Q₂ are two charges and d is distance between two.
.1 = 
If Q₁ becomes three times , force will become 3 times . Hence force becomes .3 N in the first case.
Force F = .3 N
If charge becomes one fourth , force also becomes one fourth .
F= 
= .025 N.
The answer would be A which is waves.

If it’s wrong oh well because I just guest buh glad to help :)
<h3><u>Answer;</u></h3>
c) created when tectonic plates converge
<h3><u>Explanation;</u></h3>
- According to the plate tectonics theory, earthquakes, volcanoes and mountain building process occur due to the interaction of the rigid plates on the earth's crust.
- <u>Mountains are as a result of volcanoes which are created by the movement of plate tectonics, which erupt and form mountains.</u> Formation of these mountains is as a result of compression of sediments caused by the collision of two convergent plate boundaries.
- It's along the convergent plate boundaries that interactions occur which creates volcanic activities and mountain building.
