Answer:
B: False
Explanation:
The second law of thermodynamics states that: the entropy of an isolated system will never decrease because isolated systems always tend to evolve towards thermodynamic equilibrium which is a state with maximum entropy.
Thus, it means that the entropy change will always be positive. 
Therefore, the given statement in the question is false. 
 
        
             
        
        
        
Answer:

Answer:
The average speed for the entire run is 12 km/h.
Explanation:       
The average speed is given by the following equation:

Where:
 : is the total distance
: is the total distance
 : is the total time
: is the total time
If during the first hour, they ran a total of 13 kilometers and then, they ran 5.0 kilometers during the next half an hour we have:


Hence, the average speed is:

Therefore, the average speed for the entire run is 12 km/h.

According to newton's first law, massive objects have larger inertia than
small objects, which means it takes more force to move bigger things
than smaller
ones.
