Question

Q 10) Arpan has learnt that materials which can be drawn into wires are called ductile. Which of the following is not a ductile material? / ਅਰਪਣ ਨੇ ਇਹ ਸਿਖਿਆ ਕਿ ਜਿਨਾਂ ਪਦਾਰਥਾਂ ਨੂੰ ਖਿੱਚ ਕੇ ਤਾਰਾਂ ਬਣਾਈਆਂ ਜਾ ਸਕਦੀਆਂ ਹਨ,ਉਹਨਾਂ ਨੂੰ ਖਿਚਨਯੋਗ ਕਹਿੰਦੇ ਹਨ।ਹੇਠ ਲਿਖਿਆਂ ਵਿਚੋਂ ਕਿਹੜਾ ਖਿਚਣਯੋਗ ਪਦਾਰਥ ਨਹੀਂ ਹੈ? * 0/2 (a) Silver ਚਾਂਦੀ (b) Sulphur ਸਲਫਰ (c) Copper ਤਾਂਬਾ (d) Aluminium ਐਲੂਮੀਨੀਅਮ​

Answer 1

Answer:

sorry

Explanation:

sorry preet i don't know the answer where are you from

Answer 2

Answer:

Sulphur is non-metal which is not have ductile properties.

Explanation:

Silver is a soft metal with excessive thermal and electrical conductivity. It is malleable and ductile much like gold. However, the silver content in ores mines in India is about 1% received as a derivative withinside the mining of gold and lead. Thus, silver is noticeably high-priced to be drawn into wires for the industries.

Ductility is the physical belongings of the metal this means that if we pull the metal it’s going to stretch instead of break. In different words, a fabric’s capacity to go through giant plastic deformation under tensile stress earlier than rapture is known as the ductile properties of the material. The ductile substances are nickel, copper, metallic, etc.  

The property of a metal that explains the breaking of steel without forming stretch below tensile stress is known as brittle. It is likewise known as an unexpected failure. The brittle substances are glass, solid iron, etc.

Ductility is vital attention in engineering and manufacturing, defining a fabric appropriate for certain manufacture and potential to absorb mechanical overload.
