I push a wall and it pushes back as long as I do - where does this infinite reaction force comes from?
The reaction force is not infinite; it is finite. For example, if you push with a force of 100N, the wall will push back with a force of 100N.If you are thinking that this requires an unlimited amount of energy, then you are confusing the concepts of force and energy. Energy is only required if the force is applied over a certain distance - the energy (or work) required to pull or push an object is equal to the force multiplied by the distance. In the example you give, the wall doesn't budge, so you have a force of 100 N times a distance of zero meters, equals an energy of 0 Joule.
How much force is needed to push a force of 100 newtons back?
Also 100 newtons. Actually, that would only hold it in place - to push it back, you would need slightly more than 100 newtons.

How does pressure vary with area if force is applied?
Pressure is defined as force per area or P = F/A. So, if I push my hand against a wall with the force of 10 newtons, I am dispersing that 10 newtons over the area of my hand. If my hand is say 7in * 4 inches, that would give a total area of 28in^2. The pressure I am exerting on the wall would be P = F/A = 10 Newtons/(28in^2) = .36 N/in^2. If instead of pushing the wall with my hand, I push a nail against the wall, I am now applying the same 10 newtons of force, but my area is a fraction of the size. Since A goes down, pressure will go up. So now, my area may be A = 0.1in^2. P = F/A= 10Newtons/(.1in^2) = 100 N/in^2.
How is torque different from a force?
Torque is basically the equivalent of a force, for rotational movement. It always involves a force, but torque also depends on how far you push or pull, from the axis of rotation. A torque has units of force x distance (for example, in SI units, newton x meters). Thus, a force of 100 N at 1 meter from the axis of rotation (100 N-m) has the same effect (the same torque) as a force of 50 N at 2 meter (also 100 N-m).

How is distance and direction affect work?
Work is the product of force and distance, or w = F x d. Now, theoretically, if you push an object 100 yards to the east, and then turn it around and push it 100 yards back to the staring point, you did NO work, because distance has a vector component. But, if you just push it in one direction only, the work done will be the product of the force applied times the distance moved.
How long do you have to work out to burn 100 calories?
Depends on a lot of things, but mainly your weight, and how hard you push. Me, I'd go through 100 cals in about 10 minutes of casual jogging.

How does construction use slope?
It reduces the force needed to move the load up. Just think of it, it takes less force to push a cart with 100 kg of bricks on a slope or is it easier to lift it up directly to a height of 10m?
I am suffering from stomach acid and i usually do push up exercise 100 times but nowadays it is very hard to pass motion for meis it cause of push up exercise?
The push ups should not cause you to have limited motion. You may have an ulcer or even a pulled muscle. A doctor can diagnose you.
