Question

5 examples of desirable and undesirable effects of friction​

Answer 1

Answer:

All the world’s a stage,

And all the men and women merely players;

They have their exits and their entrances,

And one man in his time plays many parts,

His acts being seven ages. At first, the infant,

Mewling and puking in the nurse’s arms.

Then the whining schoolboy, with his satchel

And shining morning face, creeping like snail

Unwillingly to school. And then the lover,

Sighing like furnace, with a woeful ballad

Made to his mistress’ eyebrow. Then a soldier,

Full of strange oaths and bearded like the pard,

Jealous in honour, sudden and quick in quarrel,

Answer 2
