Coal is the answer to the question
Answer:
1299 N/m²
Explanation:
Applying,
P = ρgh............... Equation 1
Where P = pressure of water at the bottom of the container, ρ = density of water, h = height of water in the container, g = acceleration due to gravity.
but,
V = πr²h............ Equation 2
Where V = volume of water, r = radius of the container
make h the subject of the equation
h = V/πr².................. Equation 3
From the question,
Given: V = 200 liters, = 200000 cm³, r = 70 cm
Constant: π = 22/7
Substitute these values into equation 3
h = 200000/[(22/7)(70²)]
h = 12.99 cm
h = 0.1299 m
Also given
Constant: g = 10 m/s², ρ = 1000 kg/m³
Substitute these values into equation 1
P = 0.1299(10)(1000)
p = 1299 N/m²
Answer:
La persona está nadando en la alberca a una profundida de 5.575 metros.
Explanation:
La presión absoluta (
) experimentada por la persona es la suma de la presión atmosférica (
) y la presión hidrostática de la columna de agua de la alberca (
), medidas en kilopascales. Es decir,
(1)
(2)
Donde:
- Densidad del fluido de la alberca, medida en kilogramos por metro cúbico.
- Aceleración gravitacional, medida en metros por segundo al cuadrado.
- Profundidad de la persona en la alberca, medida en metros.
Si sabemos que 
, 
, 
y 
, entonces la profundidad de la persona en la alberca es:
La persona está nadando en la alberca a una profundida de 5.575 metros.
So the acceleration of gravity is 9.8 m/s so that’s how quickly it will accelerate downwards. You can use a kinematic equation to determine your answer. We know that initial velocity was 19 m/s, final velocity must be 0 m/s because it’s at the very top, and the acceleration is -9.8 m/s. You can then use this equation:
Vf^2=Vo^2+2ax
Plugging in values:
361=19.6x
X=18 m
