Answer:
The depth is 5.15 m.
Explanation:
Lets take the depth of the pool = h m
The atmospheric pressure ,P = 101235 N/m²
The area of the top = A m²
The area of the bottom = a m²
Given that A= 1.5 a
The force on the top of the pool = P A
The total pressure on the bottom = P + ρ g h
ρ =Density of the water = 1000 kg/m³
The total pressure at the bottom of the pool = (P + ρ g h) a
The bottom and the top force is same
(P + ρ g h) a = P A
P a +ρ g h a = P A
ρ g h a = P A - P a
h=5.15 m
The depth is 5.15 m.

ooh thanks but don't give me advise
The most important function of a landfill is to store and get rid of solid waste which it provides an area where waste is disposed of and can be managed properly in order to reduce health and environmental risk<span />
Answer:
Explanation:
Given:
mass, m = 87.5kg
Velocity, V = 0.900c
now,
the relativistic kinetic energy id given as:
...........(1)
where,
= relativistic factor, given as; 
Now, the classical kinetic energy is given as:
..........(2)
Dividing the equation (1) by (2) we get
or
substituting the values in the equation we get,
or
...get food to people in need when they need it...
