The gravitational field strength is 10 N/kg. What is the pressure on the base of the sink due to the liquid? 2200 Pa 22 Pa 220 Pa 11 000 Pa P =h ρ g = 0.20 x 1100 x 10 = 2200 Pa 2 / 5 2) Which of the following locations is likely to have the largest pressure? Under the blade of a knife cutting vegetables. Under the tyre of a truck. Under the tyre of a bicycle. Inside a can which is connected to a vacuum pump. 3 / 5 3) Fig. 1 shows an inflated balloon that is placed inside a container that is connected to a vacuum pump. 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: remains the same Pressure change outside: decreases Pressure change in the balloon: decreases Pressure change outside: decreases Pressure change in the balloon: increases Pressure change outside: decreases Pressure change in the balloon: increases Pressure change outside: increases 4 / 5 4) Which of the following locations would a person experience the highest air pressure? On the top of Mount Everest. Inside an aeroplane which is flying at 10 000 metres. In a coal mine 100 metres below sea level. At sea level. 5 / 5 5) The diagram shows a simple mercury barometer. When the mercury barometer is brought to the top of a mountain, the height h of the mercury column decreases. Which statement explains this? The pressure in the space above the mercury column has increased. Atmospheric pressure has increased. There is less air above the mountain. Some mercury has evaporated. Your score is Restart quiz
