5. A jogger runs at 9 m/s, and is trailed by a bumblebee moving at 5 m/s and emitting a frequency of 270 Hz. What frequency does the jogger hear if the speed of sound in air was 336 m/s? V=V Soos = S source (V 1 V 205) f=f Source S = ? V= 11

= 424 m away. How long (in s) until the dolphin hears an echo? Assume the water temperature is 25°C, and While floating in the ocean, a dolphin emits a sound wave directed toward the hull of an ocean liner d the speed of sound in the water is 1,533 m/s. S

a bat can detect small objects such as an insect whose size is approximately equal to one wavelength of the sound the bat makes. if bats emit a chirp at a frequency of 20.2 kHz and the speed of sound in air is 323 m/s, what is the smallest insect a bat can detect? answer in units of mm

40.The heart of a patient beats at a rate of seventy per minute. What is the frequency of the heartbeat? 1.17 Hz 70 Hz 0.0143 Hz 0.857 Hz

A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 7.69  104 Hz, and if the speed of sound in air is 343 m/s, what is the smallest insect a bat can detect? ?mm

An organ pipe that is 1.75 m long and open at both ends produces sound of frequency 303 Hz when resonating in its second overtone. What is the speed of sound in the room? m/s

If a stationary dolphin emits a call at a sound frequency of 53 kHz. The sound wave reflects off a fish moving directly towards the dolphin. And the sound wave echo returns at a frequency of 55 kHz. What is the speed of the fish? The speed of sound is 343 m/s.

and 4.00 m from the other? Ans. 4.1 rad 7. A bat flies toward a wall at a speed of 5.0 m/s. As it flies, the bat emits an ultrasonic sound wave with frequency 30 kHz. What frequency does the bat hear in the reflected wave? 8 The solution of travelling wave v(cos(kx - wt) is Ans. 30,888 kHz w²0²y a²y

1. The warning tag on a lawn mower states that it produces noise at a level of 93 dB. What is this in watts per meter squared? 1= ✓ W/m²

A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 5.89 104 Hz, and if the speed of sound in air is 343 m/s, what is the smallest insect a bat can detect?mm
