Binaural Beat Brain Wave
The threshold of the human ear is around 20,000 Hz, so the frequency of this radio signal is far higher than what the ear can detect.
a.The sound of the crack of the bat travels at a speed of
v = 331 m/s + 0.6T
= 331 m/s + (0.6)(30.0°C)
= 349 m/s
For the fan sitting in the seats at the ballpark,
d = 8.0 m + 2.0 m = 10.0 m
Since the frequency of the sonar ping increased, the ship must be
approaching the engineer.
