The resultant decreases from 0 degrees until the angle is 180 degrees and then increases until 360 degrees.
Yes., and their being along the coordinate axes does not change the answer.Consider the vectors: i, -i and j where i is the unit vector along the x axis and j along the y axis. The resultant of the three is j.
If the angle decreases, the magnitude of the resultant vector increases.
This is an increase of 14.2857%.
(12/5 x 100) - 100 = 140 percent. The percentage change between 5 and 12 is a 140 percent increase.
Vectors are represented by arrows. They represent something that has magnitude, expressed by the length of the arrow, and direction shown by the direction the arrow head points away from the reference system. Vector addition is really quite simple. Make sure all vectors of interest use the same units of magnitude. Pick a vector and place the tail of the arrow on the intersection of the reference system. Do not change it's direction or magnitude. Take the next vector you wish to add and place the tail at the tip of the arrow of the first vector. Again, do not change either direction or magnitude. Do this with all vectors you wish to add. Remember, NEVER CHANGE MAGNITUDE OR DIRECTION. When you draw a new vector from the origin of the reference to the tip of the last vector in the chain of vectors being added, the new vector is the sum of all the vectors in the chain.
That follows directly from the addition of vectors by components - here you are adding real numbers, so the commutative law applies.

The direction will change; the magnitude of the resultant force will be less.

Change in magnitude.
Acceleration
A resultant force causes a change in velocity.
Newton's second Law states that when a resultant force acts on an object with constant mass, the object will accelerate and move in the direction of the resultant force. The product of the mass and the acceleration of the object is equal to the resultant force. The direction of the acceleration has the same direction as the resultant force. If the force stated in this question is always greater than the opposing force (i.e. friction, air resistance...) the body will continue to accelerate and its velocity will increase.
Increase the masses.
40% increase.
50% increase.
