Is it tiring to push hard against a solid wall even if no work is done?
Not sure if this is a real physics question... but yes, pushing against a wall is tiring even though no "work" is being done. Its isometric conditioning. Think of this: Put your hands in front of you and press them together as hard as you can for as long as you can. This will tire you out pretty quick.
What happens to the kinetic energy of a moving object if the network done is positive?
That really depends on the situation. Work done on an object may increase its kinetic energy; but it may also just increase its potential energy (e.g., when pushing something upwards against the force of gravity).
How much work is done if a force of 20 N is applied on an object that remains stationary?
20 joules

In what activities are you doing work in its scientific meaning A sitting still on a rock B pushing against a rock but not moving it C pushing the rock over a cliff?
In activity B, where you are pushing against a rock but not moving it, work is being done in its scientific meaning as the force you apply results in a displacement over time, even though the rock doesn't move. In activities A and C, no work is being done because there is either no displacement in the case of sitting still on a rock (A) or no force causing a displacement in the case of pushing a rock over a cliff (C).
