A wooden block of volume 5.26 times 10^-4 m^3 floats in water, and a small steel object of mass m is placed on top of the block. When m = 0.400 kg, the system is in equilibrium and the top of the wooden block is at the level of the water. (Take the density of steel to be 8 g/cm^3.) (a) What is the density of the wood? kg/m^3 (b) What happens to the block when the steel object is...

A 1,200Kg boat is sunk in the harbor and sits on the bottom a depth of 30m. A plan to raise the boat using ping pong balls has been put in place. The boat is sealed so that the ping pong balls can be added to the boat and will remain in the boat displacing enough water to raise it to the surface. An average ping pong ball is 4 cm in diameter. (a) Assume that all of the ping...

Imagine we shape 0.1x103 kg of solid steel into a small boat model which can displace 0.1 m3 of water at its maximum capacity. What is the additional buoyant force we get from this ship compared to the buoyant force we would get by submerging this chunk of solid steel directly into water, in unit of N? ρ(steel) = 7.8x103kg/m3. ρ(water) = 1.0x103kg/m3. Use g = 9.8 m/s2
