Question 6
please help solve
(a) In the figure below, a metal cube of length L = 0.5 m and mass 500 kg is suspended by a cable in an open tank of fresh water of density 1000 kg/m³. (i) Calculate the magnitude of a buoyant force on the cube. [1 mark] (ii) Determine the tension in the cable. [2 marks]
(b) An empty cylindrical bucket, mass 20 kg, a radius of 0.8m and total height 2.0 m is floating straight up on a lake with some height is submerge in water. Then, a water from the lake is poured into the bucket to fully submerge it. Calculate the mass of the water that is poured into the bucket to fully submerge the bucket given water density from the lake is Pater = 1000kg/m³ [3 marks] (c) The U-tube in the figure below contains two liquids in static equilibrium. The water in right arm has a density of 998 kg/m³ and the density of oil in the left arm is unknown. Measurement gives / = 135 mm and d= 12.3 mm. What is the density of the oil?
