Part a - whale communication.
blue whales apparently communicate with each other using sound of frequency 17.0hz , which can be heard nearly 1000km away in the ocean. what is the wavelength of such a sound in seawater, where the speed of sound is 1521m/s ?
? 1 =
m
part b - dolphin clicks.
one type of sound that dolphins emit is a sharp click of wavelength 1.50cm in the ocean. what is the frequency of such clicks?
f =
khz
part c - dog whistles.
one brand of dog whistles claims a frequency of 26.0khz for its product. what is the wavelength of this sound?
? =
cm
part d - bats.
while bats emit a wide variety of sounds, one type emits pulses of sound having a frequency between 39.0khz and 78.0khz . what is the range of wavelengths of this sound?
? min,? max =
mm
part e - sonograms.
ultrasound is used to view the interior of the body, much as x rays are utilized. for sharp imagery, the wavelength of the sound should be around one-fourth (or less) the size of the objects to be viewed. approximately what frequency of sound is needed to produce a clear image of a tumor that is 1.00mm across if the speed of sound in the tissue is 1550m/s ?
f =
mhz

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
