Answer:
671.76 kg or 6590 N
Explanation:
So the buoyant force generated by the floating ice is equals to the mass of water displaced by the submerged ice. We also need to account for gravity of ice. The resulting additional mass that the ice sheet can support is the difference between the mass of water displaced by ice and the mass of ice submerged totally in water.
So the ice piece can support an additional 671.76 kg of bear, or 671.76 * 9.81 = 6590 N
D. Frictional
The other three are energies while frictional energy is not
I believe that they are called thought experiments.
The way in which objects exert forces on each other is described by Newton’s 3rd law of motion
