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>
The object is in a state of equilibrium.
Answer:
150N

300*0.5= x
150N= x
force= 150N
