True.
Yes because the sound waves are closer together or more frequent. A drum is usually larger than a teakettle, so it will have a lower resonant frequency.

false because it does
There is no best frequency. If you train a dog correctly any frequency the dog can hear will control it. Your voice, whistle, 'silent' whistle. All are acceptable.
yes, a whistle sound is high pitched sound
its mostly mammals such as dogs cats rats
Cymbals, muted trumpets, triangle. bats, dog whistle ...
a change in the sound's frequency caused by the motion of the sound's source
Yes it does. Higher pitched sounds have higher frequencies than lower pitched sounds.
A series of high frequency moans, clicks and whistle, some which are audible to our ears.
It isn't louder (loudness has to do with intensity, and a small whistle can't generate that much intensity), it's a higher frequency. In the range that is inaudible to humans.
The longest whistle recorded belongs to a blue whale, which can produce sounds that can travel hundreds of miles underwater. Their low-frequency whistles can reach lengths of up to 188 decibels.
The whistle works by causing the smooth flow of air to be split by a narrow blade, sometimes called a labium or windcutter, creating a turbulent vortex which causes the air to vibrate. The length of the chamber typically defines the resonance frequency.
