the sound would be called "ultrasound"
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.
Yes
Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing.

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.
No. Frequency is just a measure of "how often". It can be less than, equal to or greater than normal.
The ultra sound having frequency is higher than the human ear can be respond.it is greater than 46khz.
No.
No... 2g is only 2000mg
