The box will stay in the same place because the forces are balanced and will not create acceleration (movement) in either direction. The net force applied is zero.
*The physical effect (tension) would depend on what the box is made of. If it is made of an easily damaged material like cardboard it may rip or break. If it is slippery, both may lose their grip and fall.

This link should answer your question. http://en.wikipedia.org/wiki/Physiological_antagonists Basically they have opposite effects to the body. The term antagonist is a medical/physiological term used to describe this effect.
An example would be a book placed on a table. The book's weight is acting perpendicular to the table and the reaction of the table on the book is also acting perpendicular to the table, but both thse forces are opposite in direction and equal in magnitude, the reasons the book and the table are satble and in equilibrium
Nothing! If the two forces are equal and opposite then they will cancel each other out. What will happen next is described in Newton's First law when it says "An object in motion will stay in motion unless acted upon by an outside force". Two equal and opposite forces have the same effect as no force, therefore the object's motion will remain the same as if it had never been acted upon by the two opposite forces.
weight is the effect of gravity acting on mass,the greater the mass the greater the effect on gravity will have on it therefore the greater the weight. eg. if the mass is 50kg and gravity is 10N the the weight is 500N,if the mass increases to 100kg the the weight would increase to 1000N
Yes, an object can have a negative net force acting on it, which means that the forces acting on the object are in opposite directions and the overall effect is a force in the negative direction.
It doesn't. All gravity does is create a pair of forces, in opposite directions, between the center of the object and the center of the Earth, that's proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Gravity has no effect on the magnitude, number, or direction of other forces that may be acting on the same object.
Alcohol does not give you energy; it has the opposite effect on your body by acting as a depressant and slowing down your central nervous system.

Net force is a vector sum because it considers both the magnitude and direction of the individual forces acting on an object. When multiple forces are applied to an object in different directions, the net force provides a single resultant force that accounts for the combined effect of all the forces.
-- When forces of unequal magnitude are added, the magnitude of the sum can be anything between the difference and sum of the individual magnitudes, depending on the angle between them. -- When forces of equal magnitude are added, the magnitude of the sum can be anything between zero and double the individual magnitudes, depending on the angle between them.
Two forces work against each other when they act in opposite directions and have equal magnitude. The net effect is a cancellation of their respective effects, resulting in a balanced system. This equilibrium can result in a stationary object or a constant velocity motion.
That simply means that when analyzing forces, the direction is quite often relevant. For example, if two people push an object in the same direction, the result will not be the same as if they push in opposite direction. A vector is simply a physical measurement that has both a magnitude (number) and a direction.
Alcohol does not give you energy; it actually has the opposite effect on your body by acting as a depressant, slowing down your central nervous system and making you feel tired or sluggish.
If they are balanced and equal they have no overall effect on the acceleration of an object.
The min net force magnitude you can have is (20 - 12) = 8 N, when the two forces are directly opposite in directions. When the two forces align, the net force magnitude becomes the maximum, which is equal to (20 + 12) = 32 N. You can guess that the net force magnitude is somewhere between 8 N and 32 N, when the two forces are at an angle other than 0o or 180o. Let us say the larger force is A and the smaller force is B, at an angle, alpha, to one another. Then the net force magnitude, |C| = |A| + |B|*cos(alpha). The magnitude of C, |C|, depends solely on cos(alpha), since |A| and |B| are fixed. When alpha = 0o, |C|= |A| + |B| (maximal); when alpha = 180o, |C|= |A| - |B| (minimal). Note that max(cos(alpha))=1 and min(cos(alpha))=-1. ================================
Increasing the angle between two forces will decrease the magnitude of the resultant force. When the angle is 180 degrees (opposite directions), the forces will cancel out, resulting in a zero resultant force. Conversely, when the angle is 0 degrees (same direction), the forces will add up, resulting in a maximum resultant force.
