If you're referring to chemical polarity, then water is a common polar substance. It's polar because at the particle level, a water molecule has a positive end and a negative end (caused by unshared electrons between hydrogen and oxygen.) As a result, water is able to dissolve many other substances which are also polar (like salt.)
Some examples of real-world applications of inclined planes include ramps for wheelchair access, sloped roads for vehicles to climb steep hills more easily, and conveyor belts used in industries for transporting materials up or down.
Real objects are physical entities that exist in the observable world. They can be touched, seen, heard, smelled, or tasted. Examples include tables, chairs, books, and cars.
Convection currents can be found in real-world examples such as in the atmosphere, where they drive weather patterns and wind movements. In the ocean, convection currents play a role in the circulation of water and nutrient distribution. In the Earth's mantle, convection currents are responsible for the movement of tectonic plates and the formation of volcanic activity.
A real machine is a physical device that performs mechanical tasks in the physical world. It operates based on principles of physics and mechanics to convert inputs into outputs. Examples include cars, washing machines, and computers.
No, a galvanometer does not have polarity. It is a device used to detect and measure small electric currents. The deflection of the needle in a galvanometer indicates the presence and direction of the current but not the polarity.

Did you mean "real world examples of parallel lines"? If so, railroad tracks are a perfect example.
