A stationary tuning fork is in resonance with an air column in a pipe. If the tuning fork is moved with
a speed of 2 m/s

in front of the open end of the pipe and parallel to it, the length of the pipe should

be changed for the resonance to occur with the moving tuning fork. If the speed of sound in air is
320 m/s
, the smallest value of the percentage change required in the length of the pipe is__________

Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.

Answer:

$f = \frac{V}{4L {}^{1} }$

$f( \frac{320 + 0}{320 - 2} ) = \frac{V}{4L {}^{2} }$

$➦ \frac{L {}^{2} }{4} = \frac{318}{320}$

$\frac{4 - L {}^{2} }{4} = \frac{2}{320}$

$\frac{△L}{L} \times 100\% = \frac{20}{32} \% = 0.62\%$
