A barge floating in fresh water (ρ = 1000 kg/m3) is shaped like a hollow rectangular prism with base area A = 550 m2 and height H = 2.0 m. When empty the bottom of the barge is located H0 = 0.45 m below the surface of the water. When fully loaded with coal the bottom of the barge is located H1 = 1.8 m below the surface. 1)Find the mass of the coal in kilograms. 2) How far would the barge be submerged (in meters) if m2 = 450000 kg of coal had been placed on the empty barge?

A U-tube open at both ends is partially filled with water (Figure a). Oil having a density of 790 kg/m³ is then poured into the right arm and forms a column L = 5.18 cm high (Figure b). Shield Po FU h Water Oil a (a) Determine the difference h in the heights of the two liquid surfaces. cm (b) The right arm is then shielded from any air motion while air is blown across the top of the left arm until the surfaces of the two liquids are at the same height (Figure c). Determine the speed of the air being blown across the left arm. Take the density of air as 1.20 kg/m³. m/s

A spherical weather balloon is filled with hydrogen until its radius is 4.10 m. Its total mass including the instruments it carries is 16.0 kg. (a) Find the buoyant force acting on the balloon, assuming the density of air is 1.29 kg/m3. kN (b) What is the net force acting on the balloon and its instruments after the balloon is released from the ground? kN (c) Why does the radius of the balloon tend to increase as it rises to higher altitude? Because the external pressure     with increasing altitude.

A flat-bottomed aluminum fishing boat has a mass of 60 kg and an area of 4.0 m2. When it is launched into the water (density 1,000 kg/m3), how far (in m) below the surface of the water does the bottom of the boat sink? B. A fisherman and his buddy climb into the boat. If they, along with their gear, have a mass of 300 kg, how much farther (in m) does the boat sink into the water?

The iceberg that sunk Titanic was estimated to be 150 m in length and 33 m above the water the ocean surface. If the density of ice is 917 kg/m³ and the density of seawater is 1025 kg/m³, how much of the iceberg lied below the surface of the water? O 11.5% 89.5% 89.2% 11.8%

A spherical weather balloon is filled with hydrogen until its radius is 4.30 m. Its total mass including the instruments it carries is 18.0 kg. (a) Find the buoyant force acting on the balloon, assuming the density of air is 1.29 kg/m³. 4.21 kN (b) What is the net force acting on the balloon and its instruments after the balloon is released from the ground? X kN (c) Why does the radius of the balloon tend to increase as it rises to higher altitude? Because the external pressure decreases v with increasing altitude.
