Answer: D
Explain:
For example, an unopened soda in a bottle has a uniform composition and is a homogeneous mixture. Once you open the bottle, bubbles appear in the liquid. The bubbles from carbonation are gasses, while the majority of the soda is liquid. An opened can of soda is an example of a heterogeneous mixture.
        
                    
             
        
        
        
The answer should be D, because there is no motion involved. Unless, of course, you are heavier than a large cargo crate.
Work is expressed in Joules, which are Newtons times meters. Meters are a unit of distance, so if the force (in Newtons) is not producing any distance, there is no work.
