A boat has a porthole window, of

jekas [21]

Answer:

F = 534.6[N]

Explanation:

We must find the pressure exerted by the water at the depth of the boat, by means of the following equation.

$P=Ro*g*h$

where:

Ro = density of sea water = 1027 [kg/m³]

g = gravity acceleration = 9.81 [m/s²]

h = wáter Depth = 6.25 [m]

Now replacing:

$P=1027*9.81*6.25\\P=62967.93[Pa]$

The net force is:

$F = P*A\\F = 62967.93*0.00849\\F = 534.6[N]$
