Question

with the help of an activity show that nylon is a shortest fibre​

Answer 1

Answer:

Activity -Take threads of cotton and nylon(synthetic fibres) of about same length and thickness.. Hang cotton, thread from a stand. Attach a pan at the other end of the thread.Add weights, one by one, to the pan until the thread breaks (see fig.) note the total weight required to break the cotton thread. This gives a measure of the tensile strength of the thread. Repeat the same with nylon thread.

CONCLUSION

From this activity, We can say that-

Much more weight is required to break the nylon thread showing that nylon thread has a grater strength than any other cotton thread
