From the description of the substances, the best answer would be option A. Substance D would generally function as a solvent because it has the largest composition in a solution. A solvent in a solution has the highest percent composition among all components involved. Having a composition of more than 50% would mean that a substance is the solvent.

Answer:
Velocity of the box: 10.67 m/s
Explanation:
Recall that impulse is defined as the force applied times the time the force is in action. Then we can obtained the value of the impulse given to the box as:
Impulse = F * time = 33.3 N * 2.35 s = 78.225 kg m/s
then we use the momentum of the box at that precise time to find its velocity recalling that :
Momentum = mass * velocity
Then
78.225 kg m/s = 7.33 kg * v
v = 78.225/7.33 m/s = 10.67 m/s
