A small ferryboat is 4.30 m wide and 5.50 m long. When loaded truck pulls onto it, the boạt sinks an additional 4.50 cm into the river. What is the weight of the truck? kN

A vat contains a mixture of oil and water. The water forms a lower layer which is 0.8 m deep, and above it there is an oil layer 0.3 m thick. The density of water is 1000 kg/m³, and the density of oil is 800 kg/m3. Find the force on a flat door at the bottom of the vessel that has a cross-sectional area of 0.5 m2. The acceleration due to gravity is 9.81 m/s2. Oil, P. = 800 kg/m3 h. = 0.3 m %3D Water, pw = 1000 kg/m3 %3D hw = 0.8 m A = 0.5 m2

A fishing line has attached to it a hollow plastic float 3.15 cm in diameter and having a mass of 1.50 g. Find the mass of a lead weight that, when attached to the bottom of the float, will cause the float to be half submerged.

When a cube-shaped object with a mass of 235 kg is supported fully underwater by a lifting cable, the tension in the cable is Tair = 617 N. Calculate the density of the object and the volume of the object based on the information above. Based on the density what is the material?
