Atmospheric pressure is 1.0 × 105 Pa. The density of the water in the lake is 1000 kg/m3 and the gravitational field strength g is 10 N/kg. What is the total pressure at this depth? 8.0 × 104 Pa 1.1 × 105 Pa 2.0 × 104 Pa 1.8 × 105 Pa 2 / 5 2) The heights of the two mercury levels of a simple mercury barometer are shown. What is the pressure of the point P. 760 mmHg 480 mmHg 380 mmHg 0 mmHg 3 / 5 3) 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? 210 Pa 480 Pa 2100 Pa 830 Pa 4 / 5 4) A small submarine is submerged in water.
