1. What is copolymer? Give examples. 2. Mention the differences between natural fibre and synthetic fibre.
3. Write two uses of rayon and nylon each.

hope it helps :D if u want u can break it down if you want it in a small sentence.

A copolymer is a polymer that is made up of two or more monomer species. Many commercially important polymers are copolymers.

 Examples include polyethylene-vinyl acetate (PEVA), nitrile rubber, and acrylonitrile butadiene styrene (ABS).

What's the difference between natural and synthetic fabrics? Natural fabrics, like merino wool, cotton, cashmere, and silk, are made of fibers that are produced by animals and plants. Synthetic fabrics, like polyester, nylon and acrylic, are "man-made" fibers that are created in laboratories.

Rayon is used in textile industry for making textiles. Rayon is used for making tyre cords.It is also used for making carpets and surgical dressings. Acrylic is widely used in the world today for several purposes, offering an alternative to glass due to its safe due to its safety

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

happy to
