A tall tube is evacuated and its stopcock is closed. The open end of the tube is immersed in a container of water (density 10^3

kg/m^3) that is open to the atmosphere (pressure 10^5 N/m^2). When the stopcock is opened, how far up the tube will the water rise?

Answer:

10.19 m

Explanation:

Water will rise to equalize the pressure inside and outside the tube.

The equation of pressure is given by

p=\rho gh

Where,

p = Pressure of air = 10⁵ N/m²

ρ = Density of water = 10³ kg/m³

g = Acceleration due to gravity = 9.81 m/s²

h = Height the water will rise

h=\frac{p}{gh}\\\Rightarrow h=\frac{10^5}{9.81\times 10^3}\\\Rightarrow h=10.19\ m

∴ The water will rise by 10.19 m.

Un recipiente contiene una capa de aceite (densidad 600 kg/m³) de 17.1 cm, sobre otra de agua (densidad 1000 kg/m³) de 28.4 cm d
MAVERICK [17]

Answer:

P=3792.55 Pa

Explanation:

Para resolver este problema, vamos primero a hacer un dibujo de la situación (ver imagen adjunta).

En este caso, tanto el peso del aceite como el peso del agua están ejerciendo una  presión sobre el fondo del recipiente, por lo que la presión total será la suma de ambas presiones. La presión está dada por la equación:

P=\rho gh

por lo que la presión total será:

P_{total}=P_{aceite}+P_{agua}

P_{total}=\rho _{aceite} gh_{aceite}+\rho _{agua} gh_{agua}

y sustituímos (mucho cuidado de convertir las alturas a metros)

P_{total}=(600 kg/m^{3})(9.81 m/s^{2})(17.1x10^{-2}m)+(1000 kg/m^{3}) (9.81 m/s^{2})(28.4x10^{-2}m)

lo cual nos da como resultado:

P=3792.55 Pa

nata0808 [166]

A truck moves 60 kilometers east from point A to point B. At point B, it turns back west and stops 15 kilometers away from point A.

Displacement=15km east

Distance=60+(60-15)=105km

ans is A. The total distance is 105 kilometers, and the total displacement is 15 kilometers east.
