4. Loudspeakers A and B are vibrating in phase and are playing the same tone, which has a frequency of 250 Hz. They are set up as in Figure 17.7, and point C is located as shown there. However, the distance between the speakers and the distance between speaker B and point C have the same value d. The speed of sound is 343 m/s. What is the smallest value of d, such that constructive interference occurs at point C?...

Part B.
The answer is 1.07 rad/s.
(12.2.20) In the diagram below, the upper cylinder has mass M1 = 3.00 kg and the lower cylinder has mass M2 = 2.00 kg. Their radii are a and 3a, where a = 10.0 cm, as shown. Initially M1 is rotating clockwise at 8.00 rad/s and M2 is rotating counterclockwise at 4.00 rad/s. They are both rotating about the same axis passing through the centers of the two cylinders. (a) M1 is dropped...

A sound wave a frequency of 20 kHz emerges through a circular opening that has a diameter of 0.78 m. Concepts: The diffraction angle for a wave emerging through a circular opening is given by sin(theta) = 1.22 /D, where is the wavelength of the sound and D is the diameter of the opening. What is meant by the diffraction angle? the angle that the sound wave bends away from the center before passing through the opening the location of...

Solve for the final angular velocity (ans. 22.9 rad/s)
Let's look at a new example to see how this works. Consider a solid wheel of radius 0.5 m and mass of 2 kg. The wheel sits at the top of a hill that has a height of 10 m. Starting from rest, the wheel rolls without slipping down the hill to the bottom. What is the velocity of the wheel at the bottom of the hill? The key to this...

3. A ping-pong ball is a hollow sphere that has a radius of 0.100 m and a mass of 0.00270 grams. At one point during a game of table tennis the ball is initially rotating at 100 rad/s counterclockwise (around its center of mass) before being hit by a paddle. The hit from the paddle changes the angular velocity to 60 rad/s clockwise in a time of 0.200 seconds. (a) Through how many radians will the ball turn...
