Answer 1

Answer:

Follows are the correct solution to this question:

Explanation:

The kids pulley in the same place, as you'll see. It implies that we already have an unstable power case, which is also referred to it as the supervisory review, since forces may not cancel. This condition will result in the creation of an unmatched net force to move or re-pay the object and is what we'll find.

First, let's discover the intensity the two guys were exercising. It is easy, it can add the strength of either of them. Size 5N + 5N = 10N  

If both of the kids' powers (10N) overcome the resistance or strength of the cabinet itself, the cabinets will pass. It succeeds to overcome the cabinet's opposition, its cabinet shifts into a boys' power.
