| A girl is floating in a freshwater lake with her head just above the water. If she weighs 600 N, what is the volume of the submerged part of her body? | 0.06 m^3 |
| What is the tension in a wire supporting a 1250-N camera submerged in water? The volume of the camera is 8.3 x 10^-2 m^3. | 436.6 N |
| A metal object is suspended from a spring scale. The scale reads 920 N when the object is suspended in air, and 750 N when the object is completely submerged in water. Find the volume of the object. Find the density of the metal. | 0.017 m^3; 5412 kg/m^3 |
| What is the size of the buoyant force that acts on a floating ball that normally weighs 5.0 N? | ??? |
| What is the apparent weight of a rock submerged in water if the rock weighs 54 N in air and has a volume of 2.3 x 10^-3 m^3? | 31.46 N |
| If a rock weighing 54 N is submerged in a liquid with a density exactly twice that of water, what will be its new apparent weight reading in the liquid? The volume of the rock is 2.3 x 10^-3 m^3. | 8.92 N |
