A 1.00 kg beaker containing 2.00 kg of oil (density =916.0 kg/m 3) rests on a scale. A 2.00 kg block of iron is suspended from a spring scale and completely submerged in the oil, as shown in figure. Determine the equilibrium reading of both scales.

A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.

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.)

A scale reads 85 N when a piece of aluminum is hanging from it. What does it read when it is lowered so that the aluminum is submerged in water? The density of alluminum is 2700 kg / (m ^ 3); Useg = 9.8 m/s ^ 2 Calculate answer to two decimals .

When an object is suspended from a spring balance (figure (a)) the reading is 8.80 N. When the suspended object is submerged in water (figure (b)) the reading is 4.40 N. Determine the density of the object. kg/m³ (a) spring scale Mog (b) spring scale FB FRA A TO & Mog

You place an open bottle filled with olive oil (density 880 kg/m^3) in a container filled with water so that the surfaces of both liquids are at the same level. The bottle has a hole in it 18cm below the surface that is initially closed with adhesive tape, as shown in (Figure 1).       Determine the vertical distance Δh between the oil surface and water surface after the tape is removed and the equilibrium is reached. Assume that the volume of water is much greater than the volume of olive oil, so that the decrease in the water level is negligible.

A block of wood, whose volume is V = 0.050 m3, is attached to the bottom of a lake by means of a rope and it is completely immersed in the water. The block has a density of 0.75 × 103kg/m3 (while water has a density of 1.0 × 103 kg/m3). a) Compute the buoyant force and the weight acting on the block.b) What is the tension in the rope?c) If we cut the rope, the block will start accelerating towards the surface. Calculate its acceleration.
