Because upward buoyant force is slightly higher than gravitation force for this particular object
Answer:
Hey
I have no idea when YOUR assignment is due.
Newtons 1rst law:
An object that has constant motion will remain at that speed unless acted on by an external force.
Newtons 2nd law:
F=ma (force=mass*acceleration)
Newtons 3rd law:
when a force is applied to an object, there will be an opposite but equal reaction.
Acceleration:
How much your speed increases/decreases per unit of time.
I wrote all that^
Answer:
Newton's second law: F=ma.
Force = mass x acceleration
This basically means, that the more massive something is, and the faster it is going, the more force the object will have.
So, the factors that can be used to find acceleration are:
F=ma
a=F/m
So, we see that the correct answer is A, mass and force.
Let me know if this helps!
