Answer
0.1 sec
Reason — Sound persists in the human ear for about 0.1 second due to a phenomenon called persistence of hearing.
This means that even after the sound source stops vibrating, the sensation of sound continues in the ear for a short duration.
This property helps in the continuity of sound, such as in speech and music, preventing abrupt breaks between successive sounds.
