Which equation accurately represents the work done when a force of 4.0N moves an object 1.2m?

The equation that accurately represents the work done when a force moves an object is defined by the formula W = Fd, where W is work, F is the force applied, and d is the distance over which the force is applied. In this case, the force is 4.0 N and the distance is 1.2 m. Therefore, using the correct units for distance (meters) is essential for consistency and accuracy in the calculation of work.

Using the values provided in the correct form: W = (4.0 N)(1.2 m) directly shows how the work done is calculated by multiplying the force with the displacement in the same units. The resulting value will reflect the amount of work done on the object.

The other choices introduce incorrect variables or use inappropriate units, such as seconds, or misrepresent the calculation of work by altering the relationship between force, distance, and the calculation method. Only the choice with the proper units (Newtons and meters) and the correct equation reflects the physical definition of work in physics.
