The force that is shown by the muscular strength of the fiqure skater is the gravitational force.
<h3>What is the solar system?</h3>
The solar system is composed of the sun and the planets. The sun is at the center of the solar system and it is surrounded by the planets. There are nine planets that surround the sun in the solar system and the planets move round the sun in concentric orbits.
We know that the solar system is held together by the gravitational force that acts between the sun and the planets. This is why the solar system is said to be heliocentric.
Coming back to our analogy in the question, the skater is being used as a model for understanding the solar system. Thus, the force that is shown by the muscular strength of the fiqure skater is the gravitational force.

The water reclamation, the greywater usage, and the desalination processes are kind of similar, but also kind of different.
The water reclamation is a process in which the wastewater through chemical and biological treatments is cleaned from the polluters, so that it can be returned into the environment and not cause any damage.
The greywater is a wastewater from the households and offices that doesn't have fecal contamination. This water is not suitable for drinking, but it is also not in a very bad state, so it is used for the toilet flushing, laundry washing, for irrigation.
The desalination is a process through which the saline water is stripped of the salt, in order to be suitable for drinking. This is not a widely used process, but some places like the countries on the Arabian Peninsula have to do it because there is not a single stream or river with freshwater with constant flow.
When salt or sugar is added water moves from inside the cells to the outside solutes by osmosis, causing a partial dehydration of the cell, known as plasmolysis, that interferes with microorganism multiplication.
