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

More of the turtles' ancestors who acted in thisway survived to reproduce, passing thisbehavioral trait to their offspring.
B lack of interest in biodiversity conservation
The best way to define military codes is : B. Secret languages used for communcuation
By using this, we minimized the risk of enemy listening to the conversation and managed to turn the condition over
