Question

За какой промежуток времени распространяется звуковая волна в воде на расстояние 29 км, если ее длина равна 7,25 м, а частота колебаний 200 Гц? даю 20 балов только решите с дано со всем прошу нужно срочно пожалуйста

Answer 1

Дано:
расстояние-29 км
длина волны-7.25 метров
частота колебаний-200 Гц
найти: Т
решение:
скорость=частота*длину волны
скорость=7.25*200=1450 метров в секунду
время=расстояние:скорость
время=29000:1450
время=20 секунд

Answer 2

Calculation of the Time for Sound Wave to Travel in Water

To calculate the time it takes for a sound wave to travel a distance of 29 km in water, we need to use the formula:

Time = Distance / Speed

In this case, the distance is given as 29 km, and we need to find the speed of sound in water. The speed of sound in a medium depends on the properties of the medium, such as its density and elasticity.

Unfortunately, the search results did not provide the necessary information to directly calculate the speed of sound in water. However, we can make an estimation based on the typical speed of sound in water, which is around 1,500 meters per second (m/s).

Using this estimation, we can calculate the time it takes for the sound wave to travel 29 km in water:

Time = Distance / Speed = 29,000 m / 1,500 m/s = 19.33 seconds

Therefore, it would take approximately 19.33 seconds for the sound wave to travel a distance of 29 km in water, assuming the speed of sound in water is around 1,500 m/s.

Please note that this is an estimation, and the actual speed of sound in water may vary depending on various factors such as temperature, salinity, and pressure.

I hope this helps! Let me know if you have any further questions.
