Fig. 2 shows the balloon after the vacuum pump was switched on for a few minutes. What pressure changes have occurred within the balloon and the air outside the balloon (in the container)? Pressure change in the balloon: decreases Pressure change outside: decreases Pressure change in the balloon: increases Pressure change outside: increases Pressure change in the balloon: remains the same Pressure change outside: decreases Pressure change in the balloon: increases Pressure change outside: decreases 2 / 5 2) The following box has a mass of 200 kg. What is the maximum pressure the box can exert on the floor? 33 kPa 3.3 kPa 1.7 kPa 17 kPa 3 / 5 3) A small submarine is submerged in water. The pressure acting on the submerged submarine depends on the volume of the water the density of the water the volume of the submarine the surface area of the submarine 4 / 5 4) A brick of mass 1.0 kg has dimensions 20.0 cm by 8.0 cm by 6.0 cm. When it lies on a horizontal surface, what is the maximum pressure it can exert? 2100 Pa 830 Pa 480 Pa 210 Pa 5 / 5 5) A sink is filled to a depth of 0.20 m with a liquid of density 1100 kg/m–3. The gravitational field strength is 10 N/kg. What is the pressure on the base of the sink due to the liquid? 22 Pa 2200 Pa 11 000 Pa 220 Pa P =h ρ g = 0.20 x 1100 x 10 = 2200 Pa Your score is Restart quiz
