Show hintHide hint
Refer to the definition of buoyancy.
Question 5.
A cube with a volume of 0.5 m³, made of metal with a density of 7800 kg/m³, is placed in water. Determine whether it will float or sink.
Show hintHide hint
Compare weights with buoyancy.
Question 6.
An object submerged in two liquids with densities of 800 kg/m³ and 1200 kg/m³ experiences a buoyant force of 100 N when fully submerged in both. What can you determine about its ability to float?
Show hintHide hint
Focus on how different liquid densities affect buoyancy.
