28 The diagram shows a tuning fork above a tube of air of length 25 cm. A stationary wave is set up in the tube with the same frequency as the tuning fork. The lower end of the tube is sealed. This is the minimum length of tube with the lower end sealed that creates a stationary wave. Which other lengths of tubes, sealed at their lower end, will also create a stationary wave? A 37.5 cm and 50 cm B 50 cm and 75 cm C 75 cm and 100 cm D 75 cm and 125 cm

In the figure shown below, one end of a cord is attached to the floor and the other end is attached to a small set of essentially massless wheels through a slot in a track on which the wheels roll without friction. As a result of this arrangement, the upper end of the cord is essentially free. At equilibrium, the cord is vertical and motionless. When it carries a small amplitude wave, the cord is under a uniform tension of 1.20 N. The cord has a mass of 5.80 g and a length of 85.0 cm. (a) Find the speed (in m/s) of the transverse waves in the cord. m/s (b) The cord's vibration possibilities are a set of standing-wave states, each with a node at the fixed bottom end and an antinode at the free top end. Find the node-antinode distances (in m) for the first three harmonics. Enter your answers from the lowest to the highest harmonic. m m m (c) Find the frequency (in Hz) of each of these states. (Enter your answers from simplest to more complicated.) Hz Hz Hz (d) What If? The wheels get stuck on the track and are unable to move, hence making the cart stationary. Determine the node-antinode distance (in m) and frequency of vibration (in Hz) for the third harmonic. distance m frequency Hz

Figure 6 shows a boy sitting on a swing and being pumped (pushed) by a harmonic force Fosin⁡ωt where Fo is the force amplitude and ω is the angular frequency of pumping in the horizontal direction. This forced oscillation can be modelled by a simple pendulum which consists of a lumped mass m swinging at a distance L from the pivot. (i) Write the equation of motion for this pendulum under forced vibration. (ii) Find the amplitude of angular swing based on the assumption of a small angle. (7 marks) Figure 6
