Is work done if you push a car that has run out of gas?
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.

Of corse,potential energy of pencil is increased.Therefor work done
Does an object have to move in order for work to be done?
Work = force x distance. If distance = 0, work = 0 because force x 0 = 0.
Is work being done when someone is sitting on a cushion on the floor?
Well. Work is being done. While sitting down, the person does not apply any force. He lets himself be dragged down by gravity. During this process, the gravitational force is doing the work. The work done by the gravitational force is stored as the potential energy present in the compressed cushion.
What is the rate of the work being done known as?
Power. It is usually measured in Watts (or horse-power in vehicles).
How do you determine a work done is positive sign or negative sign?
If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.

Why work done on the system is negativeand it is positive when its done by the system?
First, there are certain sign conventions. It could be defined in a different way, but things are traditionally done in a certain way. Second, if work going out of the system is defined as positive, then it is quite logical that work going into a system should have the opposite sign.
Is work being done when someone is typing a letter?
Yes it is being done, if the person doing it is doing it as part of a paid job or because they run a business and the letter is needed for the business. If it is being typed for school it may also be considered work, but of a different kind. And from the view of physics, since energy is being expended by the person typing, and perhaps by the machinery being used, work is being done. However, if you are at work and typing a letter to your grandmother, that is not the kind of work you are being paid for and your employer would say work is not being done.
