Well a Hz is a unit of frequency. It's define as the amount of time it takes pattern to oscillate in one full cycle.
so 12 Hz is the oscillation of a cycles 12 times per seconds.
A billion.
12^2 + 12 = 144 + 12 = 156 or, 12^2 + 12 = 12(12 + 1) = (12)(13) = 156
12
12 x 12 x 12 x 12 x 12 = 125 = 248,832
The Answer Is 12 12 x 12 x 12 = 1728 12 x 12 = 144 144 x 12 = 1728

3 cycles / 12 seconds = 0.25 cycles / second, or 0.25 Hz.3 cycles / 12 seconds = 0.25 cycles / second, or 0.25 Hz.3 cycles / 12 seconds = 0.25 cycles / second, or 0.25 Hz.3 cycles / 12 seconds = 0.25 cycles / second, or 0.25 Hz.
The photon energy of 1022 Hz is 4.22664452E-12 electron volts.
Frequency of femal adult is 165 hz to 255 hz.
Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit

c = λ × f λ in meter f = 1/T Hz = 1/s Therefore, C= 2 (m) X 6 (Hz)= 12 m/s
The hearing frequency range for sheep is estimated to be 100 to 30,000 Hz. Sheep have a lifespan of 10 to 12 years.
10 Hz 10 Hz
440 Hz, 660 Hz, and 880 Hz.
Low hz
The sensitivity of the human ear ranges from 20 Hz to 20 kHz. Under ideal conditions in a laboratory, humans have detected sounds as low as 12 Hz.
