Question

ਪੈਰਾਸ਼ੂਟ ਬਣਾਉਣ ਲਈ ਹੇਠ ਲਿਖਿਆਂ ਵਿੱਚੋਂ ਕਿਹੜਾ ਫਾਈਬਰ ਵਰਤਿਆ ਜਾਂਦਾ ਹੈ? Which of the following fibres is used for making parachutes? पैराशूट बनाने के लिए निम्नलिखित में से किस फाइबर का उपयोग किया जाता है? *
ਪਲਾਸਟਿਕ Plastic प्लास्टिक
ਟੇਰੀਲੀਨ Terelyne टेरीलीन
ਨਾਈਲਾਨ Nylon नायलॉन
ਸਟੀਲ Steel स्टील​

Answer 1

Answer:

NYLON FIBER is used in the making of parachutes.

• nylons are very strong and elastic that why they used in parachutes.  

• the polymers which are linked by an amide linkage. and are a synthetic polymer is known as nylons we can prepare nylons by condensation of polymerization of diamines with carboxylic acids and also of amino acids and their lactams.

• terelyne =    Terylene is a practical example of polyester. Like nylon, it is popular for its use in making synthetic textile.

• steel  = steel is not a polymer it is a mixture of alloys so we cant use steel as a fiber.

• plastic does not have an elastic property and can break so we can't use plastic also.

so option 3 nylon is correct answer.
