Canadian geese move up and down on the surface of a lake. If one moves up and down 15 times a minute and you estimate the distance between the wave crests to be 1 m, determine the speed of the water
F = rpm
F = 15/60
F = .25
V = wavelength * Frequency
v = 0.25 m/s
Thank you
To determine the speed of the water, you can use the formula: velocity (V) = wavelength (λ) * frequency (f).
Here's how you can calculate it:
1. First, determine the frequency (f) in hertz (Hz). Since the Canadian goose moves up and down 15 times a minute, you need to convert the frequency to seconds. Divide 15 by 60 to get the frequency in Hz:
f = 15/60
f = 0.25 Hz
2. Next, estimate the distance between the wave crests, which is the wavelength (λ). In this case, you estimated the distance to be 1 meter.
λ = 1 m
3. Finally, plug in the values of wavelength (λ) and frequency (f) into the formula:
V = λ * f
V = 1 meter * 0.25 Hz
V = 0.25 meters/second
Therefore, the speed of the water is estimated to be 0.25 meters per second.
