Answer:
When there is an increase in the frequency of sound waves, the wavelength decreases.
Explanation:
Given data,
The frequency of the whale changes from 200 Hz to 300 Hz
The formula for frequency and wavelength is,
λ = v/f
Where v is the velocity of the sound waves in water (1531 m/s)
The wavelength at 200 Hz is,
λ = 1531/200
= 7.655 m
The wavelength at 300 Hz is,
λ = 1531/300
= 5.1 m
Hence, when there is an increase in the frequency of sound waves, the wavelength decreases.

Answer:
rain is water because it's a liquid
Overproduction is a driving force in natural selection, as it can lead to adaptation and variations in a species. Darwin argued that all species overproduce, since they have more offspring than can realistically reach reproductive age, based on the resources available.
Answer:Tides are formed because of the interaction of the gravitational forces between the Earth, the moon, and the sun. ... Tides are made by the rising and falling sea levels with the action of gravity while waves are formed when several factors relating to the wind and water interact with each other
