if the color changes, it is neutral but if it stays the same, it is an acid.
Answer:
Resultant force, R = 10 N
Explanation:
It is given that,
Force acting along +x direction, 
Force acting along +y direction, 
Both the forces are acting on a point object located at the origin. Let the resultant force of the object is given by R. So,

Here 


R = 10 N
So, the resultant force on the object is 10 N. Hence, this is the required solution.
here's the first part but for the 2nd one all I know is that the word "compression" goes on the spirals that are closer together.
