Answer:
Explanation:
Let assume begins movement at zero point, that is, height is equal to zero. The block has an initial linear kinetic energy and no gravitational potential energy and end with no linear kinetic energy, some gravitational potential energy and work losses due to slide friction. In mathematical terms, this system can be model as follows:

Where  are linear kinetic energy, gravitational potential energy and work, respectively.
 are linear kinetic energy, gravitational potential energy and work, respectively. 
 
        
             
        
        
        
Compounds are molecules with 2 or more elements
So the answer would be the third one
CO2;H2O
 
        
             
        
        
        
The relationship between the masses of the Earth, moon and sun and their distances to each other play critical roles in affecting tides
