Question

Определить скорость звука в воде, если источник колеблющейся с периодом 0.002 с возбуждает в воде волну с длиной 2.9 м. (помоги прошу на завтра срочно нужно)...

Answer 1

V=λ/T=2,9/0.002=1450м/с

Answer 2

Calculating the Speed of Sound in Water

To determine the speed of sound in water, we can use the formula:

Speed of sound = wavelength × frequency

Given: - Wavelength (λ) = 2.9 m - Period (T) = 0.002 s

First, we need to find the frequency using the formula:

Frequency = 1 / Period

Calculating Frequency

Using the given period: Frequency = 1 / 0.002 s

Frequency = 500 Hz

Now that we have the frequency, we can calculate the speed of sound in water using the formula:

Speed of sound = wavelength × frequency

Calculating Speed of Sound

Speed of sound = 2.9 m × 500 Hz

Speed of sound = 1450 m/s

So, the speed of sound in water, given the provided wavelength and period, is 1450 m/s.
