Is 20000 greater than 25? If so, then it is a safe bet that 20000 km is longer than 25 km
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.
No. Frequency is just a measure of "how often". It can be less than, equal to or greater than normal.
True.

Infrasound is always smaller or lighter than ultrasound. For example: infrasound can be the sound of a paper clip hitting the floor, and ultrasound can be the sound of two planets colliding.
No. The frequency of gamma rays is several orders of magnitude greater than that of any sound wave.
A high-pitched sound has a greater frequency, meaning it oscillates more rapidly than a low-pitched sound. This frequency is perceived by our ears as a higher pitch.
Yes
20,000 Hz is considered a high frequency, but it may not necessarily sound loud. The perception of loudness is more closely related to the amplitude or intensity of the sound waves rather than the frequency.
Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing.

Sounds with higher amplitude have greater energy than sounds with higher frequency. Amplitude corresponds to the intensity or loudness of a sound, while frequency relates to pitch. In general, the energy of a sound wave is proportional to its amplitude squared.
A sound with a too high frequency is called ultrasonic. These frequencies are above the range of human hearing, typically greater than 20,000 Hz.
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.
Yes. 1 meter = 1000 millimeters (mm), so 200 meters = 200,000 millimeters. Convert them to the same units and then the comparison can be made. 1 m = 1000 mm ⇒ 20000 mm = 20000 ÷ 1000 m = 20 m 200 m is greater than 20 m, so 200 m is greater than 20000 mm.
Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. This frequency varies from person to person, it is approximately 20 kilohertz (20,000 hertz). This is the lower limit in describing ultrasound.
