There's no such thing as "an unbalanced force".
If all of the forces acting on an object all add up to zero, then we say that
<span>the group </span>of forces is balanced. When that happens, the group of forces
has the same effect on the object as if there were no forces on it at all.
An example:
Two people with exactly equal strength are having a tug-of-war. They pull
with equal force in opposite directions. Each person is sweating and straining,
grunting and groaning, and exerting tremendous force. But their forces add up
to zero, and the rope goes nowhere. The <u>group</u> of forces on the rope is balanced.
On the other hand, if one of the offensive linemen is pulling on one end of
the rope, and one of the cheerleaders is pulling on the other end, then their
forces don't add up to zero, because even though they're opposite, they're
not equal. The <u>group</u> of forces is <u>unbalanced</u>, and the rope moves.
A group of forces is either balanced or unbalanced. A single force isn't.
The y-component of the acceleration is 
Explanation:
The y-component of the ice skater acceleration can be calculated with the equation
where
is the y-component of the final velocity
is the y-component of the initial velocity
t is the time elapsed
Here we have:
- Initial velocity is
at 
, so its y-component is 
- Final velocity is
at 
, so its y-component is 
The time elapsed is
t = 8.33 s
Therefore, the y-component of the acceleration is

Yes. It is rather a natural phenomenon. If you search and understand the process of chemical
change or reaction that results to its chemical property outcome, it has a new
formed substance. Unlike physical change or reaction it only changes in shape
or form but the substance, compound or element in the matter is till the same.
Furthermore, when chemical change is undergoing you notice the change in shape,
size and from like the physical change but there is a change in the element,
compound or substance. When you lit a fire on a paper the fire disorients,
disorganizes and disturb the former positions of the atoms and because of the
fire as catalyzer the atoms did its behavior –changing both intrinsic and extrinsic.
Science can observe and study the natural world. Pseudoscience is not.
