A 6.2 m^3 object floats in water with 46% of its volume above the waterline. What is the force the Earth exerts on the object? The density of water is 1000 kg/m^3.

5. A block of mass 0.55 kg and density 550 kg/m3 is forced under the surface of the water by means of a spring (k = 70.0 N/m) that is fixed to the bottom of the container as shown in the figure. How much does the spring stretch? (the density of water is 1000 kg/m3). cm 741 na741 na741na741 na741 741 na741 741 na741 na741 na741 na7 na741 na741 na741 na741 no7 aha741 741 na wwwW 741 na741

The gravitational force exerted on a solid object is 5 N. When the object is suspended from a spring scale and submerged in water, the scale reads 3.5 N. Find the density of the object.

A ball was submerged in water and held in place. When released, the ball has upward acceleration of 3.5 m/s^2. What is the density of the ball?

A block of wood with a mass of 0.57 kg is floating on the surface of a lake. What is the magnitude of 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 block of wood has a mass of 3.71 kg and a density of 515 kg/m3. It is to be loaded with lead (1.13 × 104 kg/m3) so that it will float in water with 0.803 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?

You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of ?w=1.00×103 kg/m3ρw=1.00×103 kg/m3, fills the lower portion of the container to a depth of 0.221 m0.221 m. The fluid that is floating on top of the water is 0.342 m0.342 m deep. If the absolute pressure on the bottom of the container is 1.049×105 Pa1.049×105 Pa, what is the density, ?lρl, of the unknown fluid? The acceleration due to gravity is ?=9.81 m/s2g=9.81 m/s2 and atmospheric pressure is ?0=1.013×105 PaP0=1.013×105 Pa.

A hollow plastic cube of side length 80 cm is held below the surface of a lake by a cord anchored to the bottom of the lake. The cube has a mass of 85 kg and the density of the lake water is 1025 kg/m. a) What is the buoyant force exerted on the cube by the lake water? b) If the top surface of the cube is 25.4 m below the surface of the lake, what is the gauge pressure at the top surface of the cube? P. = 1.013 x 10 Pa. atm c) What is the force on the top face of the cube? Note the top face will have a square cross section and the length of the side is 80 cm.

A tank of water (SG=1.0) has a gate in its vertical wall 5 m high and 3 m wide. The top edge of the gate is 2 m below the surface of the water. What is the hydrostatic force on the gate?
