Question

Пользуясь приведённым выше рисунком Определите За какое время звуковая волна отправлено с эхолотом достигнет дна Если глубина моря равна 7500 м с За какое время звуковая волна отправлено с эхолот а возвратиться обратно если глубина моря равна 6000м

Answer 1

Ответ:

скорость звука в воде 1500 м/c

7500:1500=5 c - звук достигнет дна

(6000:1500)*2=8 c -волна вернется на корабль

Answer 2

Calculation of the Time Taken for Sound Waves to Reach the Bottom and Return

To determine the time it takes for a sound wave to travel from the echolot to the bottom of the sea and back, we need to consider the speed of sound in water and the depth of the sea.

According to the given information, the depth of the sea is 7500 meters when the sound wave is sent from the echolot, and 6000 meters when the sound wave returns.

The speed of sound in water is approximately 1500 meters per second

To calculate the time taken for the sound wave to reach the bottom, we can use the formula:

Time = Distance / Speed

1. Time taken for the sound wave to reach the bottom: - Distance: 7500 meters - Speed: 1500 meters per second

Plugging these values into the formula, we get:

Time = 7500 meters / 1500 meters per second = 5 seconds

Therefore, it takes 5 seconds for the sound wave to reach the bottom of the sea.

2. Time taken for the sound wave to return: - Distance: 6000 meters - Speed: 1500 meters per second

Using the same formula, we can calculate the time taken for the sound wave to return:

Time = 6000 meters / 1500 meters per second = 4 seconds

Therefore, it takes 4 seconds for the sound wave to return from the bottom of the sea to the echolot.

Please note that these calculations assume a constant speed of sound in water and do not take into account any other factors that may affect the propagation of sound waves in the ocean.
