a. Subsonic. b. supersonic. c. No of these.
18. The frequency of the 2nd hand top top a clock is
a. 1 hertz. b. 1/60 hertz. c. 60 hertz.
19. The sonic eight at soil level created by one aircraft will certainly be diminished if the aircraft
a. Is smaller. b. Paris higher. c. Is an ext streamlined. d. all of these. e. No one of these.

a. Decreased. b. Increased. c. Neither decreased nor increased.
21. If in ~ a concert, a wind blows straight from the orchestra toward you, the speed of the sound you hear will certainly be
a. Decreased. b. increased. c. Neither lessened nor increased.
22. A tide travels an typical distance that 1 meter in 1 second with a frequency that 1 Hz. The amplitude is
a. Much less than 1 meter. b. 1 meter. c. An ext than 1 meter. d. not enough information to say.
23. Sound travels v the waiting in the kind of
a. Transverse waves, b. longitudinal waves,
24. and radio signals travel v the waiting in the type of
a. Transverse waves. b. Longitudinal waves.
25. Pitch synchronizes to
a. frequency, b. Noise, c. Loudness,
26. whereas amplitude corresponds to
a. Frequency. b. Noise. c. Loudness.
27. A vibrating tuning fork reasons an identical fork nearby to vibrate. This is dubbed
a. Refraction. b. Resonance. c. Beats. d. Reverberation.
Reasoning: See web page 389 of the textbook for more information.
28. For this to happen, both forks must have actually the same (or multiple)
a. Intensities. b. Amplitudes. c. frequencies. d. Geometries. e. All of these.
