Answer:
B if they run out of fuel then they would probably keep going because there is nothing that would stop them other than like a planet or something.
Explanation:
Given what we know about the forces that act upon objects, we can confirm that an object to which balanced forces are applied will not be in motion.
<h3>What are
balanced and
unbalanced forces?</h3>
- A balanced force is when an object is not in motion due to all forces being matched.
- This means that for every force, there is an opposite force of the same magnitude that nullifies it.
- When one of these forces increases and overtakes its opposite, we gain motion.
- When this happens, the forces are now unbalanced.
Therefore, we can confirm that since the forces that are acting on the object are balanced, meaning that each force is matched by an opposite force of the same magnitude, the object will not move. For this object to move, the forces would have to become unbalanced by increasing the magnitude of one.

Answer:
Solution III < Solution II < Solution I < Solution IV
Explanation:
I)
Due to the rate of neutralization is 1 mol of NaOH with 1 mol of HCl and that we have equal volumes of both solution with the same concentration, they neutralize each other leaving a neutral pH (pH=7). Althought, because your titrating agent is a base the equivalence point will be a bit alkaline.
II) The same as the point I) but now the titrating agent is the acid, the equivalence point will be neutral trending a bit to acid.
III) Given that we have one strong acid neutralizing a weak base solution, in the equivalence point the the pH will be acid because the HCl (strong) dissociates compleately so we will have the 0.01 mol (100 ml of 0.1 M) of HCl with 0.01 mol>CH3NH2 (because is a weak base). How much less than 0.01 mol we have? <u>It depends of the strengh of the base and the pH will also depend on that</u>.
IV) This case is similar to the last one but with a strong base and a weak acid. So with a similar deduction the pH in the equivalence point will be alkaline (pH>7). How much? It depends on the strengh of the acid.
<u>In order of increasing pH: </u>
Solution III < Solution II < Solution I < Solution IV
