Since the phase velocity of the wave in a coaxial transmission line whose conductors are filled with dielectric material is 1.5*10^7 m/s, what is the speed of the wave propagating in an unlimited dielectric medium, which has the same properties as the dielectric filling the guide, in Mm/s (megameters/second)?

In a loudspeaker, an electromagnetic coil rapidly drives a paper cone back and forth, sending out sound waves. If the cone of a loudspeaker moves sinusoidally at 1.2 kHz with an amplitude of 3.5 mm, what are the cone’s maximum speed and acceleration?
A meteorologist for a TV station is using radar to determine the distance to a cloud. He notes that a time of 0.24 ms elapses between the sending and the return of a radar pulse. How far away is the cloud?
Sound waves entering human ear first pass through the auditory canal before reaching the eardrum. If a typical adult has an auditory canal of 2.5cm long and 7.0mm in diameter, suppose that when you listen to ordinary conversation, the intensity of sound waves is about 3.2 × 10^−6W/m^2; a) What is the average power delivered to the eardrum?
While hunting for moths to eat, a bat emits a chirp that lasts for 4.80 ms and then is silent while it listens for the echo. If the beginning of the echo returns just after the outgoing chirp is finished, how close to the moth is the bat? The bat is flying toward the moth at a speed of 4.40 m/s and the moth is flying away from the bat at 1.20 m/s. Assume it is a cool night with a temperature of 10.0°C. Speed of sound in air at 0°C is 331 m/s (see table 12.1).
The initials “AM” stand for amplitude modulation. Instead of fluctuating frequencies as above, they instead vary the amplitude, such that y= A(t)sin[2pif]t. Notice that the frequency is now fixed, but the amplitude will be inconsistent. Each AM station is assigned a frequency in kHz (1000 waves/second.) For example, 760AM is assigned a frequency of f=760kHz. a. What is the wavelength of the 760AM radio waves? b. Suppose a station has equation y=A(t)sin(1,850,000pit). What is this station?c. Sketch a graph of y=2^tsin(t) and explain graphically what the amplitude is doing.
A sun-like star is barely visible to naked-eye observers on earth when it is a distance of 7.0 light years, or 6.6 × 1016 m, away. The sun emits a power of 3.8 × 1026 W. Using this information, at what distance would a candle that emits a power of 0.20 W just be visible?
Maxwell's equations in a dielectric resemble those in vacuum but with eo replaced by K €0, where is the dielectric constant. We measure the speed of an electromagnetic wave in a certain dielectric and find u = .333 c. Determine the dielectric constant
You shout the word "hello!" into an idealized echo tube. Five seconds later, the "hello!" returns to your ears. Assuming the speed of sound is 340 m/s, how long is the echo tube? The echo is happening perfectly linearly, i.e. no bouncing off the sides of the tube. Just straight down and back again.
