calculate the pressure by sea water when diving to a depth of 100m. what is the pressure acting on the diver?

P = 981000 [Pa] or 98.1 [kPa]

Explanation:

To calculate the pressure at that depth we can use the following expression that defines the static pressure of a fluid as a function of the density and depth of the body with respect to the surface of the liquid.

where:

P = pressure [Pa]

Ro = density of the water = 1000 [kg/m³]

g = gravity acceleration = 9.81 [m/s²]

h = depth = 100 [m]

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
