Did the cart with the greatest force acting on it accelerate the fastest? Why or why not?

states that the acceleration of an object increases with increased force and decreases with increased mass.

Explanation: Notice how mass and force affect acceleration. Newton's second law. The acceleration of an object increases with increased force, decreases with increased mass, and is in the same direction as the force.

i believe the answer is three water molecules

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
