A raft is 4.20 m wide and 7.30 m long. When a horse is loaded onto the raft, it sinks 2.70 cm deeper into the water. (a)Calculate the volume of the water (in m3) that was displaced after the horse was loaded unto the raft. _______ m3   (b)Given that the density of water is: 998 kg/m3, calculate the weight of the water (in N) that was displaced after the horse was loaded unto the raft. ________ N   (c)What name is given to the weight of the water that was displaced when the horse was loaded on the raft? -Pressure force -Torricelli's force -Buoyant force -Bernoulli's force   (d)Determine the weight of the horse. __________N

A large block has dimensions of length = 0.15 m, width = 0.2 m, and depth = 0.5 m. It has a mass of 117 kg. The volume of a block, Vblock = (length) x (width) x (depth).   (a) Using the table shown, what is the block made of?  (b) If completely under water, what is the buoyant force acting on the block?

A boat displaces 5.76 m3 of water when if floats on the surface of a lake. What is the magnitude of the buoyant force acting on the boat? (The density of water is 1000kg/m3)

A life preserver is manufactured to support a 70 kg person with 25% of his volume out of the water.   If the density of the life preserver is 100 kg/m^3 and it is completely submerged, what must its volume be? Assume that the density of the person to be about the same as the density of water, 1000 kg/m^3. Express your answer with the appropriate units.

A solid block is suspended from a spring scale. If the reading on the scale when the block is completely immersed in water is 25.0 N, and the reading when it is completely immersed in alcohol of density 806 kg/m3 is 25.7 N, what are (a) the block’s volume and (b) its density?
