An organ pipe is open at both ends. It is producing sound at its n = 3 harmonic, the frequency of which is 392 Hz. Take the speed of sound to be 344 m/s. What is the length of the pipe?

Explanation:

Formula for the organ pipe of length L which is open at both the ends. So, its third harmonic frequency will be given as follows.

where,    v = speed of the sound = 344 m/s

            = 392 Hz

Hence, putting the given values into the above formula as follows.

            L =

               =

               =

               = 1.316 m

Thus, we can conclude that the length of the pipe is 1.316 m.

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

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
