Answer

(a) increase (b) $446HZ$

Work Step by Step

(a) If the speed of the sound is increased then the fundamental frequency will increase because fundamental frequency is directly proportional to the speed of sound. (b) We can find the fundamental frequency as $f_1=\frac{v}{4L}$ We plug in the known values to obtain: $f_1=\frac{348}{4(0.260-0.065)}=446HZ$
