A person clapped his hand near a cliff and hurt the echo after 5 sec. what is the distance of the cliff from the person if the speed of the sound v is taken as 340m/s

Answer»

ere's your answer......The SOUND traveled from the PLACE the person STOOD, to the cliff and then REBOUNDED back to the person , so the person heard the resound/echo.So the sound traveled TWICE the distance between him/her and the cliff.Distance between cliff and person = 340 m/sec * 5 seconds / 2       = 850 metersThanks...!!!XDSorry baby 'wink'
