Acceleration is directly proportional to net force. What is the relationship between acceleration and mass?

They are inversely related; As acceleration decreases, mass increases; As acceleration decreases, mass increases.

Explanation:

This is to keep the force the same.

F=2m•0.5a

F=0.5m•2a

Both forces have the same value, but they have acceleration and masses that are inversely proportional to eachother.

In real life, you can see it with a recoil gun. The bullet and the gun have equal but opposite forces, but the bullet accelerates faster than the gun due to its smaller mass, while the gun recoils at a slower acceleration due to its larger mass.

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

i think the answer is a, hope this is right, that would be my best guess.
