Question 4 A force of 250 N is applied to a hydraulic jack piston that is 0.02 m in diameter. If the piston that supports the load has a diameter of 0.15 m, approximately how much mass can be lifted by the jack? Ignore any difference in height between the pistons. A) 250 kg B) 700 kg C) 1400 kg D) 2800 kg E) 5600 kg Question 5 A balloon inflated with helium gas (density = 0.2 kg/m³) has a volume of 6 × 10-³ m³. If the density of air is 1.3 kg/m³, what is the buoyant force exerted on the balloon? A) 0.01 N B) 0.08 N C) 0.8 N D) 1.3 N E) 7.8 N Question 6 Which one of the following statements concerning the buoyant force on an object submerged in a liquid is true? A) The buoyant force depends on the mass of the object. B) The buoyant force depends on the weight of the object. C) The buoyant force is independent of the density of the liquid. D) The buoyant force depends on the volume of the liquid displaced. E) The buoyant force will increase with depth if the liquid is incompressible.
