bija089 [108]

Answer: El trabajo realizado al desplazar el bloque es: 75 N.m

Datos:

Fuerza= F= 25 N

Distancia= d= 3 m

Explicación:

El trabajo es el producto de la fuerza ejercida sobre un cuerpo con el desplazamiento producido por la fuerza. Para que exista trabajo, la dirección de la fuerza debe ser igual a la dirección del desplazamiento.

Trabajo= Fuerza x Desplazamiento

Reemplazando los datos:

T= 25 N * 3 m

T= 75 N.m

What happens to the boiling point of water as you climb higher up a mountain?
Maksim231197 [3]
The higher the pressure, the higher boiling point of water. At lower the pressure, the boiling point of water comes down. So, the lower pressure inreases the boiling resulting more evaporation. As we go higher in altitude, the atmospheric pressure decreases. This results in decreasing the boiling point at higher altitude and increase in boiling of water. In fact, at the sea level ,the the sea water boils at 100 degree C where atmospheric pressre is normal. However , the boiling takes place at a lower temperature at the top of a mountain due to low pressure. In other words the boling is faster at the top of a mountain than that at its foot.
