B is the only answer that makes sense.
A that would mean the car only moves 5 mi/hr
C just doesn't make sense
D the equation never mentions the velocity changing
Answer
given,
diameter = 6 m
depth = h = 1.5 m
Atmospheric pressure = P₀ = 10⁵ Pa
a) absolute pressure
P = P₀ + ρ g h
P = 10⁵ + 1000 x 10 x 1.5
P = 1.15 x 10⁵ Pa
b) When two person enters into the pool
mass of the two person = 150 Kg
weight of water level displaced is equal to the weight of person
ρ V g = 2 m g
V = 0.3 m³
Area of pool =
=
= 28.27 m²
height of the water rise
h = 0.0106 m
pressure increased
P = ρ g h
P = 1000 x 10 x 0.0106
P = 106.103 Pa
