Question

41 and 42, they are the same part, please specify decimals

Answer 1

Given:

The distance traveled by water wave is d = 6.6 m

The time duration is t = 1.69 s

The time period is T = 1.1 s

To find the speed of the water wave and the wavelength.

Step-by-step explanation:

The wave speed can be calculated as

`\begin{gathered} v=(d)/(t) \\ =(6.6)/(1.69) \\ =3.9\text{ m/s} \end{gathered}`

The wavelength can be calculated as

`\begin{gathered} \lambda=v* T \\ =3.9*1.1 \\ =4.29\text{ m} \end{gathered}`

Thus, the wave speed is 3.9 m/s

The wavelength is 4.29 m
