Answer:
9.0m and 0.009m
Explanation:
Since the hearing capacity range as from low to high. That is from 20Hz to 20000Hz.
F1 = 20Hz and F2 = 20000Hz
Also velocity is given as 360m/s
For the low capacity hearing
V = λf1
360m/s = λ × 20Hz
λ = 360m/s ÷ 20Hz
λ = 18m
Where λ = 2L
18m = 2L
L = 9m
As lo for the high frequency = 20000Hz
V = λf2
360m/s = λ × 20000
λ = 360m/s ÷ 20000
λ = 0.018m
λ = 2L
0.018 = 2L
L = 0.018÷2
L = 0.009m

Answer: The answer is Reverberating Circuit
Explanation:
reverberating circuits produces repetitive outputs. It involves signaling from one neuron to another in a linear sequence, one of the neurons sends a signal back to the initiating neuron. This is a back and forth signaling from one neuron to the neuron initiating the signal. It is involved in the control of activities that are rhythmic in nature such as breathing, the sleep-wake cycle, swinging of arms when walking.
