Final answer:
The work done when a 25 N horizontal force is applied to move a 10-kg box, causing it to move 5 meters, is 125 J.
Step-by-step explanation:
To calculate the work done, we can use the formula:
Work = Force x Distance
In this case, the force is 25 N and the distance is 5 m. So, the work done is:
Work = 25 N x 5 m = 125 J
Therefore, the correct answer is A) 125 J.
