Verified answer
The question does not have enough information for a single answer. All we can tell from the question as is is that the friciton force must be less than 5000N. To give a definite number to the magnitude of the friction force we need to know at what rate the wagon is accelerating when the pull is 5000N.

Investigate-how friction increases with increase of size of an object?
The force of friction on an object is equal to the coefficient of friction times the force perpendicular to the surface (normal force). When the mass of an object increases, the normal force increases, and the force of friction also increases. However, because the equation does not involve surface area, increasing surface area has no affect on the force of friction.
Give the ways of increasing and reducing friction?
By making the surface rough for increasing friction....... use any lubricating material to reduce the friction.. use rollers to decrease the friction force.. make less contact between 2 connecting materials..
A 8000 kg engine pulls a train of 5 wagons each of 2000 kg along a horizontal track if the engine exerts a force of 40000N and the track offers friction force of 5000N then calculate 1 the net acclera?
Ans. :- net acceleration = 40000 - 5000 = 35000 N.
What is the Force engine provides the wheels of the car equation?
Thrust or friction
Unbalanced force opposing motion between touching surfaces?
The unbalanced force that opposes motion between touching surfaces is called friction. It acts in the opposite direction of the applied force and depends on the nature of the surfaces and the force pressing them together. Friction can be reduced by using lubricants or by increasing the smoothness of the surfaces.

How one can increase the force of friction?
there are a few different things that come to mind immediately. The most prevalent being changing one or both of the surfaces making contact. for instance, rubber (as in a tire, most often) on clean, dry pavement has a static friction coefficient of 0.9 μs while rubber (again as in a tire) on wet pavement has a static friction coefficient somewhere in the ballpark of 0.25-0.75 μs.the static (and kinetic, for that matter) coefficient of friction varies between almost every pair of materials (some may be close if the surfaces are similar).additionally, the force of friction would increase the greater the mass of the object that the force is being applied to. the force of friction is calculated as follows;Ff = μ · Nwhere Ff is force of friction, μ is the coefficient of static friction, and N is the normal force (normal force is equal to the mass of the object times the acceleration of gravity. the unit of measurement for this value is newtons, and it is simply the weight of the object) Given this equation, you can see that by increasing the mass of the object, you are in effect increasing the frictional force acting on that object.hope this helped!
Which force slows down a ball when it moves?
The force of friction, which is the normal force (weight) multiplied by the coefficient of friction (how rough the carpet is).
Does a car run because of the frition or reaction force from the ground is the friction static friction or kinetic friction?
No. the car runs by how much gas you have and how much power your car engine has.
Which is the larger the kinetic friction force or the statical friction force?
Statical friction
Is friction a natural force?
friction is a natural force
What is an exapmle of a balanced force?
AN airplane traveling @ a constant speed. It's air friction is balanced by the applied force of it's engine.
