its the second part of the question that I don't understand:

according the graph shown, the net force acting on an object varies wth the object's displacement. Calculate the work down by the force on the object at the various displacements listed below (i won't bother telling you since you don't have the graph, but I figured out the work done to be these)

a)the work down = 160J
b)200J
c)480J

"state two possible outcomes of the work above being done on the object". I don't know what they mean by that...

Please explain!

Maybe they mean for two of the different displacements. Without seeing the complete question and figuree, it is hard to say.

The force of gravitation between two objects. Is 500 Newton's. What would the force of gravitation be if the distance between these two objects increased by 10 times?

When it comes to the concept of work being done on an object, it refers to the transfer of energy to or from the object by means of a force acting on it. In this case, we have the graph showing the net force acting on an object as it varies with the object's displacement.

To calculate the work done by the force on the object at the different displacements listed, you need to use the formula for work:

Work = Force * Displacement * cos(θ)

Where:
- Work is the amount of energy transferred to or from the object, measured in joules (J).
- Force is the magnitude of the net force acting on the object, measured in newtons (N).
- Displacement is the distance the object is displaced, measured in meters (m).
- θ (theta) is the angle between the force vector and the displacement vector. Since we don't have information about the angle, we'll assume it to be zero, meaning the force and displacement are in the same direction.

Now, let's analyze the given work values:

a) Work done = 160 J
b) Work done = 200 J
c) Work done = 480 J

These values represent the energy transferred to or from the object at the respective displacements.

Moving on to the next part of the question, when they ask for two possible outcomes of the work being done on the object, they might be referring to the effects of the work on the object. Here are two possible outcomes:

1. Change in Kinetic Energy: The work done on the object can result in a change in its kinetic energy. If the object gains work energy, its kinetic energy will increase, and if it loses work energy, its kinetic energy will decrease.

2. Change in Potential Energy: Alternatively, the work done can also result in a change in the object's potential energy. If the object is lifted against the force of gravity, work is done, resulting in an increase in potential energy. Conversely, if the object descends due to the force of gravity, work is done and the potential energy decreases.

These are two possible outcomes that could be associated with the work being done on the object.
