Answer:
A
Explanation:
Since acceleration is the change of velocity and f=ma, the change in velocity is dependent on force and mass. Since the force on all of the objects is the same, the one with the least mass will accelerate the most. Object A is the least massive at a mass of 0.5kg, meaning that its velocity will change the most. Hope this helps!
The last one on that list would be your answer
Answer:
both melting point and boiling points are lower
this is because it becomes easier to break those bonds (they’re actually intermolecular forces) between the atoms sinc they’re weak, and thus require less energy to break.
