Two small speakers A and B are driven in step at 720 Hz by the same audio oscillator. These speakers both start out 4.50 m from the listener, but speaker A is slowly moved away At what distance dd will the sound from the speakers first produce destructive interference at the location of the listener? If A keeps moving, at what distance dd will the speakers next produce destructive interference at the listener? After A starts moving away, at what distance will the speakers first produce constructive interference at the listener?

A toy battery-powered plane is hanging from the ceiling. With the motor turned off it is pulled to one side 0.20 m and released to swing as a pendulum. It takes 1 s to get to the far side of its swing. The plane now has the motor turned on and it flies in a circular path of radius 0.60 m. If the period of the circular motion is the same as the period of the simple harmonic motion, what is the approximate speed of the plane?

1. A surge is moving at 9 f t/s into a basin of depth 1.4 f t where the speed is zero. Find the water depth behind the surge and the drift velocity behind the surge (that is, the velocity downstream of the surge in a stationary frame of reference). 2. A river of depth 2 m flows downstream at 1 m/s. A surge of depth H moves up the river at 5 m/s relative to a stationary observer on the bank of the river. Find H.

The little brown bat is a common bat species in North America. It emits echolocation pulses at a frequency of 40 kHz, well above the range of human hearing. To allow observers to “hear” these bats, the bat detector as shown combines the bat’s sound wave at frequency f1 with a wave of frequency f2 from a tunable oscillator. The resulting beat frequency is isolated with a filter, then amplified and sent to a loudspeaker. To what frequency should the tunable oscillator be set to produce an audible beat frequency of 3 kHz?
