3. since the unbalanced forces an upward force, the object will move upward.
Explanation:
Newton's second law states that when an object is acted upon unbalanced forces, the object will experience an acceleration, whose direction is the same as the net force acting on the object, and whose magnitude is given by
where F is the net force and m is the object's mass.
From the above statement, we can say that an object accelerates in the direction of the net force acting on it. Looking at the diagram, we see that the net force on this object is upward, because the force going upward is 450 N while the force going downward is 400 N, so there is a net force:
in the upward direction. (there is no net force on the horizontal direction, since the two horizontal forces are equal and opposite)
So, the object will accelerate upward.
I am pretty sure that <span>the following whihc cannot be determined by looking at the phase diagram is definitely </span>D. system pressure. I consider this one to be correct because only this point is not included into<span> phase diagram and can't be determined itself. Hope it will help! Regards!</span>
Answer:
D
Explanation:
If in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. In an endothermic reaction, the products have more stored chemical energy than the reactants. And in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
