T = 2pi * sqrt(L/32) dT/dt = pi * sqrt(16L)/(16L) * (dL/dt) (dT/dt)*(dt/dL) = [pi * sqrt(16L)/(16L) * (dL/dt)]*(dt/dL) dT/dL = pi * sqrt(16L)/(16L) dT/dL = pi * sqrt(16(16))/(16(16)) dT/dL = pi*sqrt(256)/256 dT/dL = 16pi/256 dT/dL = pi/16

\[T = 2\pi * \sqrt{\frac{L}{32}}\] \[\frac{dT}{dL} = \frac{\pi}{16}\]
