- When an invention is created for a certain job, e.g. headphones, a number of factors occur. First of all, the invention focuses on this particular area or task. Telephones had attracted attention to communication and therefore more inventions were thought of. In addition, every invention has its own limitations/ People are also inventing new things when attempting to solve these limitations.
- For example ,the invention of "Spinning Jenny" created a necessity to accelerate weaving of cloth which had facilitated the invention of a "loom", which then had increased the demand for raw cotton, which prompted the invention of cotton gin that created the "demand for "stronger iron" to make bigger "stronger machines", enhancements in "smelting metal" led to the invention of steel.

Sound needs a material medium like solid ,liquid or gas to travel and be heard because the molecules of solid, liquid and gases carry sound waves from one place to another. Sound cannot travel through vacuum or empty space because vacuum has no molecules which can vibrate and carry sound waves.

Moment of inertia of sphere is normally expressed as;
| I = ⅖ MR2 |
Here, r and m are the radius and mass of the sphere respectively. Students have to keep in mind that we are talking about the moment of inertia of a solid sphere about its central axis above. Additionally, if we talk about the moment of inertia of the sphere about its axis on the surface it is expressed as;
| I = 7/5 MR2 |
