The pH scale goes from 0-14. 0-6.9 is acidic, 7 is neutral and 7.1-14 is basic

3 0

The range of the PH scale is 0-14, so the average range is 7.

a].When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture.

b]. The water filtered by kamal is not safe to drink .

If you run out of water, or cannot carry enough water with you for your entire trip, you may need to source drinking water from natural water sources.

Laura jala un trineo una distancia de 2000 cm usando una cuerda, con una tensión constante de 80 N. La tarea requiere de 800 J d

Andre45 [30]

Respuesta:

60°

Explicación:

Paso 1: Información dada

Distancia recorrida (d): 2000 cm

Fuerza aplicada (F): 80 N

Trabajo realizado (W): 800 J

Paso 2: Convertir "d" a metros

Usaremos el factor de conversión 1 m = 100 cm.

2000 cm × 1 m/100 cm = 20 m

Paso 3: Calcular el ángulo entre la cuerda y el suelo (θ)

W = F × d × cosθ

800 J = 80 N × 20 m × cosθ

θ = 60°
