The pressure increase at the bottom of the pool after they enter the pool and float is 106.103 Pa.
<h3>What is absolute pressure?</h3>
Absolute pressure is the force that exists in a space when there is no matter present, or when there is a perfect vacuum. This absolute zero serves as the baseline for measurements in absolute pressure. The measurement of barometric pressure is the greatest illustration of an absolute referenced pressure. In order to determine absolute pressure, a complete vacuum is used. In contrast, gauge pressure is the amount of pressure that is measured in relation to atmospheric pressure, also referred to as barometric pressure.
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 exists equal to the weight of person.
Area of pool 
Height of the water rise
P = ρ g h
P = 1000 x 10 x 0.0106
P = 106.103 Pa

Answer:
hey but the person at the top is right
Answer:
Weight of the car, normal force, drag force
Explanation:
The forces acting on the car are:
- The normal force which acts perpendicularly to the downhill plane
- The weight of the car which acts vertically downwards
- The drag force due to air resistance which acts in opposition to the motion of the car
Friction is ignored, so the force due to friction is assumed negligible
The temperature of a fluid rises when energy is given to it. This phenomenon can be described by the equation:
Q = MCp ΔT
where,
Q is the quantity of added energy.
M is the fluid's mass.
The fluid's heat capacity is denoted by Cp.
T stands for temperature change.
<h3>What happens to a fluid's kinetic energy as the temperature rises?</h3>
The mean kinetic energy of the particles in a liquid rises with temperature. The molecules' higher average kinetic energies allow them to more easily overcome the attraction forces that keep them bound together.
<h3>Which temperature rise makes liquids more fluid?</h3>
The most significant determining factor for fluidity is pouring temperature. Therefore, the fluidity increases as the pouring temperature increases.
<h3>How does a liquid react when the temperature rises?</h3>
Particles in a solid, liquid, or gas move more quickly as its temperature rises. The particles slow down as the temperature drops. When a liquid is sufficiently cooled, it turns into a solid.

A weight would be least affected since it would fall striaght down if it was say paper it would go down slower because it has more air resistance due to less weight
