Atube 1.20 m long is closed at one end. a stretched wire is placed near the open end. the wire is 0.350 m long and has a mass of 9.50 g. it is fixed at both ends and oscillates in its fundamental mode. by resonance, it sets the air column in the tube into oscillation at that column's fundamental frequency. assume that the speed of sound in air is 343 m/s, find (a) that frequency and (b) the tension in the wire.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
