Inertia is defined as ax Force. Property of matter. Change in motion. None of the above A hockey puck sliding at constant velocity across the ice is In equilibrium Nearly in equilibrium Is nowhere near being in equilibrium None of the above Burl and Paul have a total weight of 1300 N. The tensions in the supporting ropes that support their scaffold add to 1700 N.The weight of the scaffold itself must be 300 N 400 N 500 N 600 N

## Step1<br />Inertia is a property of matter that describes its resistance to any change in its state of motion. This means that an object in motion will stay in motion, and an object at rest will stay at rest, unless an external force is applied to it. Therefore, the correct answer is "Property of matter".<br /><br />## Step2<br />A hockey puck sliding at constant velocity across the ice is in equilibrium. This is because the forces acting on it are balanced, meaning there is no net force acting on the puck. Therefore, the correct answer is "In equilibrium".<br /><br />## Step3<br />To determine the weight of the scaffold itself, we need to consider the total weight of Burl and Paul, which is 1300 N, and the total tension in the supporting ropes, which is 1700 N. The difference between these two values will give us the weight of the scaffold. Therefore, the correct answer is 400 N.
