Question

A submarine is 20 m below the surface of the sea. The pressure due to the water is P. On another day, the submarine is 26 m below the surface of fresh water. The density of sea water is 1.3 times the density of fresh water. What is the pressure due to the fresh water at a depth of 26 m? A P/1.3 B P C 1.3P D 1.7P Four identical beakers are filled with equal volumes of liquids P or Q, as shown. Liquid P is denser than liquid Q. At which point is the pressure the least? An oil tank has a base of area 2.5 m² and is filled with oil to a depth of 1.2 m. The density of the oil is 800 kg/m³. What is the force exerted on the base of the tank due to the oil? A 960 N B 2400 N C 9600 N D 24 000 N
