Question

which of the free - body diagram models above can help explain why the explosion?

Explanation:

To determine the correct free - body diagram for a situation related to forces (like buoyancy or tension - weight interactions), we analyze the forces acting on the mass. The weight force \(F_W = mg\) (downward) and the upward force \(F_F\) (like buoyant force or tension). For a mass \(\frac{1}{2}m\), the weight is \(\frac{1}{2}mg\). In option C, the upward force \(F_F\) and downward weight \(\frac{1}{2}F_W\) (since mass is \(\frac{1}{2}m\), weight is half) are shown, which is consistent with force balance for a partially submerged or tension - weight system. Other options either have incorrect mass - force relationships or force directions.

Answer:

C
