Answer:
A) To true. he pressure at the bottom of the pool decreases by exactly the same amount as the atmospheric pressure decreases
Explanation:
Let us propose the solution of this problem before seeing the final statements. The pressure increases with the depth of raposin due to the weight of water that is above the person and also the pressure exerted by the atmosphere on the entire pool, the equation describing this process is
P = + ρ g y
Where is the atmospheric pressure, ρ the water density, and 'y' the depth measured from the surface.
Let's examine this equation in we see that the total pressure is directly proportional to the atmospheric pressure and depth
Now we can examine the claims
A) To true. State agreement or with the equation above
B) False. Pressure changes with atmospheric pressure
C) False. It's the opposite
D) False. They are directly proportional
A The pressure at the bottom of the pool decreases by exactly the same amount as the atmospheric pressure decreases
<h3>Further explanation </h3>Hydrostatic pressure is pressure caused by the weight of a liquid.
The weight of a liquid is affected by the force of gravity.
If a liquid is placed in a container, the higher the liquid content in the container, the heavier the liquid content is and the greater the liquid pressure at the bottom of the container.
The hydrostatic pressure of a liquid can be formulated:
Ph = hydrostatic pressure (N / m², Pa)
ρ = density of liquid (kg / m³)
g = acceleration due to gravity (m / s²)
h = height / depth of liquid surface (m)
If the container is open, then the atmospheric pressure (P₀) can be entered into the equation.
The magnitude of P₀ is usually equal to = 1.01.10⁵ Pascal (Pa = N / m²) = 1 atm
For example submarines :
The deeper a submarine is, the greater the hydrostatic pressure it experiences, so that the hull / wall of the submarine is made thick to withstand that pressure.
As a storm approaches, the atmospheric pressure drops
Because the hydrostatic pressure is proportional to the atmospheric pressure, the pressure at the bottom of the pool will also be reduced

Answer:
Explanation:
Work is equal to the product of force and distance.
The box is being pushed with an effort (force) of 45 Newtons and the distance is 3.5 meters.
Substitute the values into the formula.
