The frequency for a fundamental pipe is given as:
f = v/4L
L is equal to the length of the pipe
Since L = Lo/2 where Lo is the original length of the pipe, the
new frequency would be:
f = (v/4)/(Lo/2)
f = 2 (v/4Lo)
Since v/4Lo = fo, therefore:
f = 2 fo
Answer:

Explanation:
This is true because gravity is independent of mass. Whether it's a heavy or a light object, when dropped, they both will hit the ground at the same time. The reason is that gravity does not depend on mass.
Hope this helped!

Answer:
1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)
The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.
