It would be: Time = Distance / Speed
        
             
        
        
        
Answer:
Because the object should shrink its volume to zero, which is impossible
Explanation:
Let's talk about gases for simplicity. Ideal gases are governed by the ideal gas equation:

where
p is the gas pressure
V is the volume of the gas
n is the number of moles
R is the gas constant
T is the absolute temperature
From the formula, we see that T and V are directly proportional: therefore, in order for a gas to have an absolute temperature of zero, it must also have a volume of zero, which is impossible.
 
        
             
        
        
        
There will not be enough momentum from the first hill to cross another hill if he same or larger size because of the way potential energy and kinetic energy works it will not be able go as high as it could go on he fist hill.
        
                    
             
        
        
        
C. Mechanical, because temperature can cause solid objects to expand and contract, causing rocks to split apart.
