Question

Figure (a) below shows an object hanging from a spring scale, with the scale measuring 5.35 N. In figure (b), the suspended object is submerged in water, and the scale now reads 3.40 N. What is the density (in kg/m³) of the object? (Hint: the free-body diagram to the right of figure (b) shows the
forces acting on the object, with B and T pointing up and Mg pointing down.)

An incompressible box is completely submerged in water at a depth of 60m. The volume of the box is 8L and it has a mass of 30 kg. The buoyant force on the box is 70N.. If the box is brought to a depth of 90m, stae what the mass of the box ,volume of the box and buoyant force on the box will be? Choose one correct answer with the correct units of measure. A. Mass = 70kg Volume = 8L Buoyant force = 30N B. Mass = 30kg Volume = 8 m3 Bouyant force = 70 pound C. Mass = 30kg volume = 8L Buoyant force =70N D. Mass = 8 kg Volume = 30L Buoyant force = 70N
