The force needed to move a pencil across a desk would depend on the friction between the pencil and the desk surface. If there is low friction, only a small force would be needed. If there is high friction, a greater force would be required to overcome it.
The force that pushes a pencil is the force of your hand applying pressure to the pencil. This causes the pencil to move due to the force of friction between the pencil and the surface it is resting on.
If you push with a force of 100 N on a desk that does not move, no work is done because work is defined as the product of force and displacement in the direction of the force. Since the desk does not move, there is no displacement in the direction of the force, and thus no work is done.
You would have to overcome sliding friction to make a book move across a desk. Sliding friction is the force that resists the motion of two surfaces sliding against each other.
your using the force called muscular force.
No, if the force exerted in one direction is greater than the force exerted in the opposite direction, the desk will move in the direction with the greater force, in this case to the left. The desk will move in the direction of the net force acting on it, which is the difference between the two forces (15 N to the left - 10 N to the right = 5 N to the left).

The force that allows you to pull out a desk drawer is friction. This force is generated between the surfaces of the drawer and its tracks or slides, providing the resistance needed to move the drawer in and out.
The desk will experience a force in the direction of the push from the two people, causing it to move in that same direction as long as the force applied is greater than any opposing forces like friction.
Yes, a desk on carpet would have sliding friction. The friction between the desk and the carpet would provide resistance to any sliding motion, making it harder to move the desk across the carpet.
No, a pencil is not alive. We know we are alive because we move, grow, and change. A pencil does not move, grow or change unless we move it or change it (for example: by sharpening the pencil).
The person's push creates a force that accelerates the crate. As long as the force overcomes friction, the crate will move across the floor.

When friction increases, more force is required to push something across a surface. This is because the frictional force opposes the motion of the object, making it harder to move. Increasing the applied force can help overcome this resistance and move the object across the surface.
