Answer:
False. The net force is Zero
Explanation:
To answer this question we propose the solution of the problem.
  We have a toy where balls come in and out after crashes between them, this toy forms our system, so all the balls are parts of the system, when the balls collide with each other according to Newton's third law force and action and reaction, so it has the same magnitude, but opposite direction, this is each is applied to some of the objects.
In conclusion of the previous one for the system the net force is Zero, all are internal. Therefore, the only thing that happens is a redistribution of speeds according to the conservation of the moment.
Let's review the answer.
False. The net force is Zero
 
        
             
        
        
        
A) they have no effect on air temperature over land on the coast is False
Explanation:
- warm and cold ocean currents can influence the coastal areas only when the air is blown into the land from the sea.
- the temperature over the land increases when warm ocean currents heat the air above the ocean.
- the temperature over the land decreases when cold ocean currents cool the air above the ocean and can bring colder winds to the coastal regions.
-  so, ocean currents play a major role in regulating the air temperature over land on the coastal region.
