Answer:
-10 N, not balanced
Explanation:
Force is a vector quantity, so in order to find the net force on an object, we must use vector addition rule.
This means that if two forces acting on an object along the same line, we have to choose one direction as positive, and write the two forces with the correct sign.
In this problem, we have two forces acting along a line on the car:
- A first force of
- A second force of
Therefore, the net force on the car is:
Moreover, the net force on an object is said to be "balanced" if it is zero: in this case, it is not zero, so it is not balanced.
Answer:
Chemical and Biological weathering.

Processes that break down and weaken earth minerals are known as weathering. Over time, this can lead to erosion, in which huge sections of rock and stone are carried away, changing landscapes. Physical weathering alters the material structure of rocks, while chemical weathering alters their chemical structure.
