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
Flat layered clouds with horizontal development are called STRATUS or STRATI-FORM clouds. These clouds have a layered or spread out aspect. They form when air is forced upwards by forced convection. Forced convection can occur as a result of surface convergence or movement of a frontal boundary. Examples of stratus clouds are cirro-stratus and alto-stratus clouds.
No, marsupials are mammals like opossums, kangaroos, wombats, and bandicoots who all have pouches and give birth to live young that are not ready to live in the outside world until later as they are not fully developed. Therefore they live in their mothers pouches until they are mature enough. They mainly live in Australia, New Guinea and America.
