Answer:
As ailtitudes rises air pressure drops ...... As altitude increases , the amount of gas molecules in the air decreases - so the air becomes less dense than air nearer to the sea level. So there is less air pressure at high altitudes
This is picture describe as
More current mean less resistance
Less resistance mean more current
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.
