What else can I help you with?
A box is dragged without acceleration in a straight line across a level surface by a force of 13N what is the frictional force between the box and the surface?
13N. if a=0, the sum of all forces is zero so the force of friction is equal and opposite to the dragging force.
What is the force that opposes frictional force?
Say you are moving an object against the carpet flooring, you are the force and you are causing the object to move as well as you are creating friction between the carpet and the object. The force would be called the netforce, which is all the forces that are acting on an object.
IS THE FRICTIONAL FORCE THAT ACTS ON OBJECTS THAT ARE NOT MOVING?
Yes, the frictional force acts on objects that are not moving, opposing the motion that would occur if there were no friction present. This static friction force prevents the object from moving until a force greater than the static friction force is applied.
What is the maximum frictional force in the knee joint of a person who supports 66.0 kg of her mass on that knee?
The maximum frictional force in the knee joint would be equal to the weight supported by the knee. So for a person supporting 66.0 kg of their mass on the knee, the maximum frictional force would be 66.0 kg multiplied by the acceleration due to gravity (9.81 m/s^2), which equals 647.46 N.
Is it possible for a frictional force to increase the mechanical energy of a system?
your question is not clear but fro what i could understand, i can tell you that frictional force always opposes motion of mechanical system ( so it would decrease the system's mechanical energy) therefore i can never increase it.
How does the direction of frictional force compare to the direction of an object motion?
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
What is an example of favorable?
One of the most important frictional forces to humans is the static frictional force that the ground exerts on a body. Without this force, walking would be impossible, cars would go nowhere.

Why reproduction is important to human?
Feelings of happiness and pleasure. And without reproduction, there would be no more human beings after the present human beings die.
When do the frictional forces between two surfaces increase?
As they come into contact so tight friction would increase As roughness increases frictional force too increases.

What size force would cause an aircraft of 1200 kg to accelerate up to 6gS?
Impossible to say as you have given no frictional/resistive force.
Which surface would exert the least frictional force on your feet as you walk?
Teflon, Ice or an oiled surface.
