Question

5. Why can't you:
• Use a cooking utensil made of carbon?
• Draw wires from a piece of sulpuhur or coal?
Use nylon or jute ropes for electrical transmission?​

Answer 1

Answer:

(a) We cannot draw wires from a piece of wood or coal because they are brittle. They break down on stretching. (b) We cannot use nylon or jute ropes for electrical transmission because they are bad conductors of electricity.
