Question 4

A camera is lowered into a freshwater cave pool until it has 8.0 m of water above it. The pool is open to air, which exerts a pressure of 95 kPa on the water surface. The density of the water is 1000 kg/m3. Take g=10 N/kgg=10\ \mathrm{N/kg}g=10 N/kg. Use P=hρgP=h\rho gP=hρg. At what total pressure does the camera operate?
