A pop bottle is to be used as a musical instrument. the bottle is 26.0 cm tall and the height of the water is 9.00 cm. Treat the bottle as a pipe that is closed at one end (the surface of the water) and open at the other end.

What is the fundamental frequency of the bottle?

504.41 Hz

Explanation:

Given,

Height of the bottle, h = 26 cm

height of the water, l = 9 cm

Length of the pipe

L =h - l

L =26 - 9 = 17 cm

Fundamental frequency of closed-open pipe

v =  speed of sound, v = 343 m/s

f = 504.41 Hz

Fundamental frequency of bottle is equal to 504.41 Hz

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.
