the answer for this question is c
The "pitch" of a sound is the impression your brain forms
that corresponds to the frequency of the sound wave.
When the frequency is high, your brain says "high pitch".
When the frequency is low, your brain says "low pitch".
Answer:
Explanation:
the speed of the tsunami will be
v = distance / time
v = s/t
v = 2300 / 5.3
v = 434 miles/hour
To convert this to m/s, we should note that, 1 mile = 1609 m, and thus
434 miles/hr = 434 * 1609/3600
434 miles/hr = 194 m/s
The frequency, f is given by the formula
f = velocity * wavelength
f = vλ
f = 194 * 470
f = 91180 Hz = 91 kHz
Period, T = 1/f
Period T = 1.096*10^-5 s or
Period T = 1.096*10^-5 / 60
Period, T = 1.828*10^-7 minute
