A boat (with a flat bottom) and its cargo weigh 6,000 N. The area of the boat's bottom is 9 m2. How far below the surface of the water is the boat's bottom when it is floating in water? Answer in meters.

A block of iron is suspended from one end of an equal-arm balance by a thin wire. To balance the scales, 4.35 kg are needed on the scale pan at the other end. The density of iron is 7.87×103 kg/m3 and the density of water is 9.98×102 kg/m3. What is the volume of the block (in m3)? Next, a beaker of water is placed so that the iron block, suspended as above, is submerged in the beaker but not touching the bottom (see the figure). What mass (in kg) is now necessary to balance the scales?

The blue whale is the largest animal known to have ever existed (see the photo). It can be almost 30 m long with a mass of 1.73 x 10³ kg. Imagine a blue whale is completely submerged and at rest under the surface of salt water. What volume of salt water is displaced by the whale? Calculate your answer in gallons. Take the density of salt water to be 1030 kg/m³. Number Units Torulus/Pixabay

A raft is 4.80 m wide and 7.30 m long. When a horse is loaded onto the raft, it sinks 2.90 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? Bernoulli's force Torricelli's force    Pressure force Buoyant force (d) Determine the weight of the horse.  N
