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.
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 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.
The work done on the desk is 200 joules. Work is calculated by multiplying force applied by the distance moved in the direction of the force; in this case, 20 N x 10 m = 200 J.
The force of digging is a push force. As you push the shovel into the ground, you are exerting force on the soil to displace it and move it away from the hole you are digging.
A push or pull that acts on an object is a force.

The force of digging is a push force. As you push the shovel into the ground, you are exerting force on the soil to displace it and move it away from the hole you are digging.
Work done = force multiply by displacement so W = 20X 10 = 200 Nm now 1Nm = 1 joule then the answer is 200 J
A push or pull that acts on an object is a force.
force
When two completely equal forces are applied at one object or each other from opposite angeles. When this happens the object to which force is applied will not move because the two forces will cancle each other out.In other words, if I push a desk left at 2n and somebody else pushes a desk right at 2n the desk will not move.
The force of your pencil or pen against the desk that your paper is on if you're writing something down. The force of your paper against the desk. The force of your book against the desk. In each case, the desk exerts the identical but opposite force against the object lying on it. If that were not true, the objects would deform the desk, or the desk would form a bump where the objects are lying on it.
Yes, push is a force that occurs when an object is pushed in a particular direction. It can cause the object to move or accelerate in the direction of the push.
The direction of the friction force is always opposed to the movement. If I push my desk to the north, the friction force will be to the south - and if I don't push hard enough, it won't budge.
