Answer:
P = 400248 [Pa]
Explanation:
We can calculate the hydrostatic pressure exerted by a column of liquid by means of the following equation.
where:
Ro = density = 1020 [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = depth = 40 [m]
Therefore:
Answer:
The correct option is B
Explanation:
In part A pressure is given as
In Part B we can calculate the pressure using the formula
Where F is the force which in this case is weight which can be obtained as follow
W = Mg
Substituting 70kg for M and for g
A is the area with a value
So substituting into the above equation
for part c
A
F
Therefore
From this we see that the value of P for part B is the greatest
