Answer:

A) at the rod's geometrical center

Explanation:

Let us assume that the rod is replaced by water. And now this water volume is in translational and in rotational equilibrium.

Therefore, a net upward force must have been exerted by the surrounding liquid which acts at the center of mass of the water volume.

This force determines through the geometric center of the column of the cylindrical water  

Moreover, the force is also independent of submerged body into it

Hence, the first option is correct

El método de cristalización sirve para separar agua salada y obtener ambos componentes por separado
GaryK [48]

Answer:

Si.

Explicación:

Sí, el método de cristalización se utiliza para separar la sal del agua y obtener los componentes de la sal y del agua por separado. La cristalización es un método o técnica que se utiliza para purificar compuestos sólidos. Este proceso funciona mejor debido a las diferentes solubilidades del compuesto deseado y las impurezas que están presentes en un solvente dado. El proceso de cristalización implica enfriar agua salada para formar cristales de hielo puro. Luego, los cristales de hielo se separan de la salmuera no congelada, se lavan para eliminar la sal residual y luego se derrite la solución para producir agua dulce.
