The gravitational field strength is 10 N/kg. What is the pressure on the base of the sink due to the liquid? 220 Pa 2200 Pa 11 000 Pa 22 Pa P =h ρ g = 0.20 x 1100 x 10 = 2200 Pa 3 / 5 3) A simple mercury barometer is shown below. The barometer is brought up to the top of a hill from sea level. How do the length X and the pressure at S change as the barometer is brought up to the top of the hill? Length X: decreases Pressure at S: decreases Length X: decreases Pressure at S: no change Length X: increases Pressure at S: decreases Length X: increases Pressure at S: no change 4 / 5 4) The heights of the two mercury levels of a simple mercury barometer are shown. What is the pressure of the point P. 0 mmHg 760 mmHg 480 mmHg 380 mmHg 5 / 5 5) The heights of two levels of a mercury barometer are shown. What is the pressure at point P? 0 mmHg 740 mmHg 860 mmHg 120 mmHg Your score is Restart quiz
