you measure the depth to the bottom with a lead line and find out the bottom is 6000 meters deep. How many seconds would it take for a seconds would it take for a sound signal to leave the ship, bounce off the bottom and return to ship? Show your work

Answer:

7.838 seconds

Step-by-step explanation:

  • Assuming the sound of sound in seawater is 1531 m/s we can calculate the time taken by the signal to leave the ship and back.
  • The depth to the bottom is 6000 meters
  • The sound signal will cover the distance twice, to and fro the bottom to the ship.
  • Time is calculated by dividing the distance by the velocity or speed.

In this case;

Time = (2× distance) ÷ velocity

= (2×6000) m ÷ 1531 m/s

= 12000 m ÷ 1531 m/s

= 7.838 s

Therefore, it will take 7.838 s for the sound signal to leave the ship and bounce back off and return to the ship.
