The floor exerts 20 N of force on the chair
Explanation:
We can answer this question by using Newton's third law, which states that:
<em>"When an object A exerts a force (called action) on an object B, object B exerts an equal and opposite force (called reaction) on object A"</em>
In this problem, we can identify:
- Object A as the chair
- Object B as the floor
This means that the force of 20 N exerted by the chair on the floor is the action, and so the force exerted by the floor on the chair is the reaction. Newton's third law states that these two forces are equal and opposite: therefore, the force exerted by the floor on the chair is also 20 N, but in the opposite direction.

Before entering the closed room, the cert members should assess
the situation first. They should gather information in order to determine if it’s
safe to go or if needed assistance to the current situation. They should consider some probabilities
before they establish the decision and take an action. Especially to the current situation where there is a possibility that the smoke that they smell is coming from the room and the reason may be because there is a fire. Assessing the situation before taking an action immediately is a must, in order to prevent further harm.
