###### Question:

the same fundamental resonance frequency as the open pipe? Tong must a second pipe, closed at one end, be if it is to have (a) 90 cm (b) 75 cm (c) 60 cm (d) 45 cm 13. 60 cm long metal rod (density p=8700 kg/m) is clamped at its center. It resonates to its fundamental to tongitudinal waves of 3.00 kHz for a speed 3.6 km/s. What is the Young's modulus for the material of the rod? (a) 1.1 x 10' N/m? (b) 3.1 x 100 N/m? (c) 4.3 x 10" N/m (d) 3.4 x 10 N/m 14. The speed of compression waves in water is (with bulk modulus for water B-2.2 10 N/m")
