La erosión costera es la pérdida o desplazamiento de tierra, o la remoción a largo plazo de sedimentos y rocas a lo largo de la costa debido a la acción de olas, corrientes, mareas, agua impulsada por el viento, hielo transportado por el agua u otros impactos de marejadas ciclónicas.

Answer:

2.06 N/m

Explanation:

The system makes 10.0 complete oscillations in 17.0 s. So, the frequency of the system is

$f=\frac{10.0}{17.0 s}=0.59 Hz$

The angular frequency of the system is given by

$\omega = 2\pi f=2\pi (0.59 Hz)=3.71 rad/s$

In a simple harmonic motion, the angular frequency is related to the mass and the spring constant by

$\omega=\sqrt{\frac{k}{m}}$

where

k is the spring constant

m is the mass

Here we know

$\omega=3.71 rad/s\\m = 150 g = 0.150 kg$

So we can solve the formula to find k:

$k=\omega^2 m = (3.71 rad/s)^2 (0.150 kg)=2.06 N/m$

This process of physically separating a single phase mixture into several components would be termed simple distillation, I believe.

As it is mentioned that one is separating them based on their different boiling points.
