Work = force x distance. Answer is in joules.
100 N is a force. An object of mass about 10.2Kg would experience a gravitational force of 100N.
Work = force x distance = 200 joules
Work W done by a constant force F that produces a displacement L in the direction of the force is : W = F∙L for the case stated: W = 100N∙20m = 2 000J (joules) The mass of the object is not involved in the calculation.
The acceleration is 0. That also means that the net force is 0N since the gravity Force is 100N down and the bag of nails is 100N, the air resistance must be 100N up to balance it out and create the net force of 0N
Yes, friction can be involved, as one of the forces. For example, if I push against this heavy desk in front of mine with a force of 100N, and it doesn't budge, that means there is a contrary force of 100N. That force, of course, is friction.
100 N is a force. An object of mass about 10.2Kg would experience a gravitational force of 100N.
F = m aa = F/m = 100/20 = 5 meters per second2 .

a lever has a mechanical advantage of 5 . how heavy an object can the lever move if a person exerts 100N force on the lever?
The acceleration is 0. That also means that the net force is 0N since the gravity Force is 100N down and the bag of nails is 100N, the air resistance must be 100N up to balance it out and create the net force of 0N
net force=mass x acceleration => mass=net force/ acceleration mass= 100/ (5/2) => mass=40
A balanced force is the one in which if there is a force on one side of the object , on the other side there is a force of the same magnitude. example is a book kept on a table is at rest. 2 forces are acting on it. one is vertically downwards that is its weight(mg) while other is perpendicular to he surface(normal force exerted by the table) an unbalanced force is 2 forces acting in opposite directions have different magnitudes and the direction of the object is towards the direction of the dominant force. example is 2 children are pulling a rope one with a force of 100N and other with 50N. rope is pulled by the child applying a force of 100N.

If the box is sliding along at a constant speed, the net force acting on the box is zero.If the net force was not zero, the box would either be speeding up or slowing down.Non-zero net forces acting on objects cause the objects to accelerate. Therefore, if the net forces is not zero, the velocity of the object could not be constant.
Yes, friction can be involved, as one of the forces. For example, if I push against this heavy desk in front of mine with a force of 100N, and it doesn't budge, that means there is a contrary force of 100N. That force, of course, is friction.
F=m*a a=F/m = 300N/3000kg=0.1m/s^2
