Water sprinkler used for grass lawns beigns to rotate as soon as the water is supplied. Explain the principle on which it works.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Water Sprinkler Mechanism**: A water sprinkler is a device that distributes water over a specific area, such as a lawn. When water is supplied to the sprinkler, it flows through the pipes and exits through small holes or nozzles.

2. **Identifying the Principle of Operation**: The operation of the water sprinkler is based on a fundamental principle of physics known as Newton's Third Law of Motion. This law states that for every action, there is an equal and opposite reaction.

3. **Applying Newton's Third Law**: When water is forced out of the nozzles of the sprinkler, it creates a force in the direction of the water's exit. According to Newton's Third Law, the water exerts an equal and opposite force back on the sprinkler itself.
