Earth has few and relatively tiny sattellites other than the moon specifically because of this large moon. Note the mass ratio of our moon to our planet. It is the highest in the solar system by a large amount. This one large sattellite will over time sweep up and aggregate other smaller sattellites. Put another way, we probably did have other smaller ...

The moon is by far the largest of earths natural satellites, but is by no means the only one. There are many much smaller bodies which either orbit earth or haveĀ an orbit around the sun which is extremely similar to that of earth. The moon is the most significant and largest as it is the result of large amounts of matter clumped together that was thrown off ...

When the the earth was formed. I guess only the moon was close enough in proxmity to be attracted by the gravity of the earth or rather earth cant hold anymore natural sattelites but the moon.

There are two mechanisms. Which one is more important depends on the colloid. A large number of colloidal particles have ionisable groups on their surfaces. These are usually salts of carboxylic acids. The vast majority of organic colloids (e.g. milk) are in this class, as are colloids prepared from acidic monomers like the acrylates. In water the surface ...

John Rennie will probably have more details on the matter, but in general colloids (such as oil dispersed into soap water) are not so much stabilized by a net total charge of the mixture, but rather are stabilized by repulsions from separated charges. For example: This is a cartoon representation of what an oil droplet in soap water looks like; note that ...
