4. Analyze: What can you say about the acceleration of dividers when the pressure increases

from left to right?

if  increase the pressure in a system the acceleration should increase

Explanation:

The definition of pressure is

         P = F / A

Where F is the force and A the area

       F = P A

Let's write Newton's second law

      F = ma

We substitute

     P A = m a

So we see that the pressure is directly proportional to the acceleration, if  increase the pressure in a system the acceleration should increase
