- A 0.20kg plastic ball has a density of 750 kg/m3. What is the amount of force required to hold it completely submerged under water? Density of water is 1000 kg/m3A block of wood has a mass of 3.68 kg and a density of 587 kg/m. It is to be loaded with lead (1.13 x 104 kg/m) so that it will float in water with 0.937 of its volume submerged. What mass of lead is needed if the lead is attached to (a) the top of the wood and (b) the bottom of the wood? (a) Number Units (b) Number Units28.

- A cubic block of steel that measures 12. cm on a side is suspended in a saltwater bath by a vertical string. The steel block is completely submerged, but it does not touch the bottom surface. The string applies just enough force to keep the block from sinking further. What force does the string apply to support the block? Density of steel: 8050 kg/m3 Density of saltwater: 1030 kg/m3A metal block, with a volume of 55 cm² is hanging from a massless string and completely submerged in water. The tension in the string is 43 N. What is the mass of the block? The density of water is 1000 kg/m² To be clear, the block is entirely under water Hint: Apply Newton's 2nd law to the block.

- Over the summer I decide to supplement my income educational offerings by building a glass-bottomed boat to drive around Lake Michigan. The glass floor is a rectangle, two meter by three meters, and that floor lies one meter below the water's surface. What additional force pushes up on the glass floor due to the increased gauge pressure underwater? a 10,000 N b 40,000 N c 60,000 N d 120,000Na diving sphere has a mass of 2.05x10^5 kg and an external diameter of 12.0 meters. the sphere initially floats on the surface of the ocean. the density of the sea water is 1025 kg/m^3. a large anchor is then attached to the sphere and it sinks to the ocean floor at a depth of 1.49 km. what is the buoyant force felt by the submerged sphere? what is the tension in the anchor cable?6. A solid aluminum bar weighs 89 N in air. a. What is its volume? b. If it is suspended from a rope and totally submerged in water, what is the tension in the rope?
- You need to determine the density of a ceramic statue. If you suspend it from a spring scale, the scale reads 28.4 N. If you then lower the statue into a tub of water so that it is completely submerged, the scale reads 17.0 N. What is the density?A block of wood with dimensions 60.0 cm × 40.0 cm × 8.0 cm floats on water with 75% of its volume below the surface of the water. While floating on water, how much mass can be placed on top of the block before it is completely submerged? The density of water is 1000 kg·m−3A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.
