A container has a large cylindrical lower part with a long thin cylindrical neck open at the top. The lower part of the container holds 22.2 m3 of water and the surface area of the bottom of the container is 8.90 m2. The height of the lower part of the container is 2.50 m, and the neck contains a column of water 8.50 m high. The total volume of the column of water in the neck is 0.200 m3. What is the magnitude of the force exerted by the water on the bottom of the container? _____ MN
Balloons are usually filled with helium gas because the density of helium gas under the same conditions is one-seventh the density of air. The buoyant force given by the relation "Fb = ρ(air).g.V(balloon)" pushes the balloon upwards. People with a mass of 70 kg get on a spherical balloon with a diameter of 10 m. The number of people getting into the cabin of the balloon is 3. In this case, calculate the acceleration of the balloon during its take-off. Take the density of the air 1.16 kg / m3 and neglect the weight of the balloon and the cabin.
You threw a box full of your ex’s things with dimensions of 0.15 [m] × 0.25 [m] × 0.30 [m]. It floated along a lake with the broadest face facing down. The box is submerged to a height of 0.05 [m]. What is the mass of the piece of box? The density of water is 1000 [kg/m3].
