The ultrasonic signal sent to the seabed returns after 4.5 seconds. Determine the depth of the sea. (The speed of sound in water is 1500 m / s).
Task data: t (duration of ultrasonic signal movement) = 4.5 s.
Reference values: by condition V (speed of sound in water) = 1500 m / s.
The depth of the sea can be determined by the formula: H = 0.5S = 0.5 * V * t.
Let’s calculate: H = 0.5 * 1500 * 4.5 = 3375 m.
Answer: The depth of the sea is 3375 meters.
