A robotic research vehicle is deployed to study a hydrothermal vent at a depth of 3500 m below the ocean surface.
Suggest one reason why the hydrostatic pressure acting on the vehicle at this depth is significantly greater than the pressure it experiences near the surface at a depth of 20 m.
54 exam-style questions on Edexcel GCSE Physics 15.2 Pressure in fluids, covering 15.2.1 Atmospheric pressure and height, 15.2.2 Pressure in fluids, 15.2.3 Pressure, force and area, 15.2.4 Pressure and depth, 15.2.5 Pressure in liquids: depth and density, 15.2.6 Upthrust, and 15.2.7 Floating and sinking. Each one has a worked solution and a mark scheme showing where the marks go.
