When an object move with a constant velocity
and there are forces acting on it, this is called unbalanced force. The forces
acting on an object is a net force, which is capable of changing speed and/or
direction of motion of an object. However,
the two forces acting on the object can be added together to give the resultant force, which is a
single force that has the same effect on the object as all the individual
forces acting together.
For Part A.
The absolute value of vector A is
<span>|A | = 6
This is simply the square root of the sum of the squares of the coordinates.
For Part B
Do the same thing as in Part A
| B | = </span>√14
<span>
Part C
Simply subtract the corresponding elements resulting in
(-3, 2, 7)
Part D
</span>√62
<span>
Part E
Yes</span>

The function which is decreasing is C. <span>Air pressure in the earths atmosphere as a function of altitude.
The higher you go, the less air pressure there is because of the fewer air molecules at such altitudes.
This means that the remaining functions are either constant or increasing. </span>
