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? 1.1 × 105 Pa 2.0 × 104 Pa 8.0 × 104 Pa 1.8 × 105 Pa 2 / 5 2) What will happen if a small hole is made in the tube as shown below? air will flow into the hole and the mercury level in the tube will rise mercury will flow out of the hole and the mercury level in the tube will rise air will flow into the hole and the mercury level in the tube will drop mercury will flow out of the hole and the mercury level in the tube will drop The pressure inside the tube is lower than atmospheric pressure so air will flow into the hole. As the air rises into the airspace above the mercury it will push the mercury downwards. 3 / 5 3) The¬†diagram below shows the structure of a simple hydraulic lift. When a force F is applied at M, a force is set up at N to lift a load. What is the magnitude of force F exerted in order to lift a load of 80N at N? 4.0 N 1.0 N 1600 N 80 N 4 / 5 4) 2018 S4 EOY P1 Q10 A cube of dimensions 2.0 cm by 3.0 cm by 4.0 cm is placed on the ground as shown. Given that the density of the block is 1.8 g cm3, what is the pressure under the block? 5.4 Pa 54 Pa 0.54 Pa 540 Pa 5 / 5 5) A 95.0 kg table exerts a pressure of 1.05 kPa on its legs. When a man climbs on top of it, the pressure exerted on its legs increased to 1.90 kPa. What is the weight of the man? 17.2 N 76.9 N 1720 N 796 N Your score is Restart quiz
