Question

the death of sea is 6200 meter and the speed of sound of time is 1500 meter/second.calculate the time echo hearing

Answer 1

DEPTH = 6200 m

SPEED = 1500 m/s

THEREFORE, THE TIME TAKEN FOR SOUND TO REACH THE

SEA BED,

  T = DISTANCE / SPEED

  T = 6200 / 1500 = 4.13 sec

SAME TIME IS TAKEN FOR ECHO TO REACH TOP SURFACE

THEREFORE, TOTAL TIME TAKE,

T= 2 x 4.13 =  8.26 sec
