Final answer:
To determine the depth of the ocean at a certain point, the ship sends out a signal that bounces off the seafloor and returns to the ship. By measuring the time it takes for the signal to travel, the distance can be calculated. In this case, the signal takes 8 seconds to travel to the seafloor and back.
Step-by-step explanation:
To determine the depth of the ocean at a certain point, the ship sends out a signal that bounces off the seafloor and returns to the ship. By measuring the time it takes for the signal to travel, the distance can be calculated. In this case, the signal takes 8 seconds to travel to the seafloor and back. Since the time it takes for the signal to travel is doubled in comparison to the first scenario, the depth of the ocean is also doubled.
Let's calculate the depth of the ocean using this information:
Time taken for the sound to travel to the bottom of the Abyss and back = 8 seconds
Speed of sound in sea water = 1450 m/s
Distance = Speed x Time
Distance = 1450 m/s x 8 seconds = 11600 m
Therefore, the depth of the ocean at the bottom of the Abyss is 11600 meters.
