Last question i'm stuck on please help me through this.

Five waves pass a dock in 2.0 s. If the waves are traveling at 10.0 m/s, then what is the wavelength of the waves?

how did you get 4m?

ok, thank you for explaining

To find the wavelength of the waves, we need to use the formula:

Wavelength = Speed / Frequency

In this case, speed is given as 10.0 m/s. However, frequency is not explicitly mentioned in the question. But we can calculate it using the given information that five waves pass a dock in 2.0 s.

Frequency is the number of waves passing a given point in one second. So, we can calculate the frequency by dividing the number of waves (which is 5) by the time taken (which is 2.0 s):

Frequency = Number of Waves / Time

Frequency = 5 / 2.0 s

Frequency = 2.5 Hz

Now that we have the speed (10.0 m/s) and frequency (2.5 Hz), we can calculate the wavelength:

Wavelength = Speed / Frequency

Wavelength = 10.0 m/s / 2.5 Hz

Wavelength = 4.0 meters

Therefore, the wavelength of the waves is 4.0 meters.

4m

v = d/t

d = v*t
d = 20m/s
5 waves

Answer = 20meters/5
