A pelican is sitting on its perch in the habit as ocean waves come splashing in. The crests is the waves drench the pelican as it collided with its perch. The drenching occurs every 1.40 seconds. The crest are positioned 9.8 meters apart. What is the period of the wave? What is the frequency of the wave? Determine the speed of the Wave?

The frequency of the wave is 0.714 H Z and the speed of the wave is 7 m/s.

Explanation:

To find the frequency of the wave,

From the given data, we can find the frequency and speed of the wave.

The drenching occurs at every 1.40 seconds

   T = 1.40 seconds

To find frequency the formula used is

 F = T⁻¹

    = 1.4 ⁻¹

F = 0.714 HZ

To find speed, the formula used is

V = λ/ T

    =

V = 7 m/s.

Thus, The frequency of the wave is 0.714 H Z and the speed of the wave is 7 m/s.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
