Both drawings show the same square, each of which has a side of length L = 0.76 m. An observer O is stationed at one corner of each square. Two loudspeakers are located at corners of the square, as in either drawing 1 or drawing 2. The speakers produce the same single-frequency tone in either drawing and are in phase. The speed of sound is 343 m/s. Find the single smallest frequency that will produce both constructive interference in drawing 1 and destructive interference in drawing 2. f =

The drawing shows a square, each side of which has a length of L = 0.250 m. Two different positive charges q1 and q2 are fixed at the corners of the square. Find the electric potential energy of a third charge q3 = −4.00×10−9 C placed at corner A and then at corner B. EPEA = EPEB = q1 = +1.50×10−9 C q2 = +4.00×10−9 C

The figure below shows a cylindrical container with an outlet valve. The cylinder is filled with water until the water level is a distance L = 20 cm from the top. A vibrating tuning fork is placed near the top of the cylinder and the valve is opened so that the length L slowly increases. If the tuning fork has a frequency of f = 502 Hz, determine the next two values of L (in m ) that correspond to a resonant mode. (Assume that the speed of sound in air is 343 m/s. ) (i) first length m second length m

(a) In a minor rail yard accident, a runaway goods truck of mass 1.85×104 kg collides at u = 20.0 ms−1 with a stationary truck of mass 2.20×104 kg, as shown in Figure 3. The trucks lock together and travel at the same speed after the collision. Assume friction is negligible. Figure 3 Sketch of the runaway and stationary goods trucks, for use in Question 10. (i) Show that the speed of the trucks after the collision is 9.14 ms−1. (ii) One of the truck wheels can be modelled as a solid disk of radius 4.60×10−1 m and moment of inertia 36.5 kgm2. Calculate the magnitude of the wheel's angular momentum after the collision. (iii) The truck's linear velocity vector is in the positive x-direction using the Cartesian coordinate system shown in Figure 3. What is the direction of the wheel's angular momentum vector? Briefly explain your reasoning. (b) The train driver sounds the train's whistle. The whistle is a pipe that is open at one end and closed at the other, and it has a length of 0.480 m. The speed of sound in air is 343 ms−1. (i) Sketch the standing wave pattern of the air pressure in the whistle for its fundamental resonant frequency. Clearly indicate the open and closed ends of the whistle pipe. (ii) Hence calculate the frequency of the sound made by the whistle's fundamental resonance. (c) An observer standing on a bridge above the train track hears the whistle as the train approaches at a speed of 40.0 ms−1. (i) Show that the whistle frequency perceived by the observer is 13.2% greater than the frequency perceived by the driver. (ii) Describe how the sound of the whistle, as heard by the observer, will change as the train approaches and goes past the bridge.
