Question 8 1 pts A tank contains a liquid with density p = 930 kg/m³, and the pressure at the surface of the liquid is Psurface= 1300 Pa. What is the pressure, in the unit of Pa, at a point in the liquid where the depth is 0.29 m from the surface of the liquid? Use g = 10 m/s² for the acceleration due to gravity. Question 9 1 pts A large tank contains a liquid with density p = 1120 kg/m³. What is the pressure difference between two points in the liquid if the height difference of the two points is 2.6 m? Use g = 10 m/s² for the acceleration due to gravity. Answer a positive pressure in the unit of Pa.
