Walking along the beach, you notice that a new wave reaches the shore every 3.8 s , and you estimate the wave crests to be 2.5 m apart. at what wave speed c are the waves moving?

Explanation:

1. Data:

a) period = 3.8 s

b) λ = 2.5 m

c) c = ?

2. Physical principles and formula:

              distance     = speed     ×      time

            wavelength = speed      ×       T

                      λ         =      c         ×       T

                 meter      = (meter/second)  ×   second

                      m        =               (m /s)    ×     s

3. Solution:

the higher the current the higher the mag field around it the higher the influence on the compass

i believe the answer is a hope it and is correct
