A. dimensionless
Coefficient of rolling friction will always be less than that of sliding friction. Hence more force is required to overcome sliding friction. Because the force = coefficient of friction x normal force (ie weight of the body)
quality of the Surface is affected to the Coefficient of friction
You need two different materials to determine the coefficient of friction. Without another material you cannot know what the coefficient of friction is.
With what material? Coefficient of friction is for two materials.
The coefficient of friction is the same in this case.
The coefficient of static friction is always larger because it takes more initial force to move an object that is at rest.

No. Coefficient of friction is not measured in units.

The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
Limiting friction is just the maximum static friction force (if you go over that point static friction becomes kinetic friction).Let f = frictional force,c = coefficient of frictionN = Normal forcefmax = cN = limiting frictionAlthough the term coefficient of limiting friction is not really used, I'd assume it would just be "c" (it's a coefficient after all). So they would be the same.If you meant is coefficient of friction the same as limiting friction, than the answer is no. Coefficient of friction is just the "c" in the equation. Limiting friction however is the product of the coefficient and the normal force.

The coefficient of friction is dimensionless; it has no units.
With what material? Coefficient of friction is for two materials.
The coefficient of friction is a scalar quantity which has no direction which does not have an angle.
A higher coefficient of friction indicates that two surfaces in contact have a greater resistence. A lower coefficient of friction indicates that the two surfaces in contact have less resistence. Soccer cleats on grass have a greater coefficient of friction than skates on ice.
