To find the depth of the sunken ship using the information provided, we can follow these steps: ### Step 1: Understand the Problem We need to find the depth of a sunken ship based on the time it takes for ultrasonic waves to travel to the ship and back. The total time taken for the waves to travel to the ship and return is given as 2.0 seconds. ### Step 2: Identify the Variables - **Time (t)** = 2.0 seconds (total time for the wave to travel to the ship and back) - **Velocity (v)** = 1450 m/s (speed of ultrasonic waves in seawater) ...
