construction of machinery
Answer is Right!
Answer is Wrong!
The correct answer is: D. construction of machinery
Non-metals are widely used in the construction of machinery because they are strong, lightweight, and durable. They are also non-conductive, which makes them safe to use in machines that generate electricity.
Here is a brief explanation of each option:
- A. water boiler – Non-metals are not typically used in water boilers because they are not as good at conducting heat as metals. This means that they would not be as efficient at heating water.
- B. fertilizer – Non-metals are not typically used in fertilizers because they do not contain the nutrients that plants need to grow.
- C. aeroplanes – Non-metals are used in some parts of aeroplanes, such as the windows and the body. However, they are not as widely used as metals in aeroplanes because they are not as strong.
