Water pressure in a lake is greater . a. at the bottom b. at the surface c. at any point, for pressure is the same d. throughout midway to the bottom

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

With i really need the correct answer!

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
