Use the dimensions of a small soft drink bottle to calculate its fundamental resonant frequency when empty. Assume the bottle is 17 cm tall. It forms a closed-end pipe.

504.4 Hz

Explanation:

The fundamental resonant frequency of sound in closed end pipe containing only air is given by

f = v/4L

v = speed of sound in air = 343 m/s

L = Length of closed pipe = 17cm = 0.17 m

f = 343/(4×0.17) = 504.4 Hz

this a false

explanation:

iron would move it is magnetic there is a mag field around the current in the wire
