Rock concerts and whispers are examples of a high-amplitude sound and a low-amplitude sound.
The largest displacement of sound wave constituents from their resting positions is referred to as amplitude. It stands for the loudness or intensity of a sound, to put it simply. Here are some illustrations of both high and low-amplitude sounds:
High Amplitude Sound: An illustration of a high amplitude sound is a rock concert with loudspeakers blaring songs at full intensity. The concert speakers produce sound waves with a tremendous amplitude, creating a powerful, strong sound that can be heard from a great distance.
Low Amplitude Sound: A low amplitude sound is something like the sound of a whisper. The sound created when someone whispers is calm and soft and not as loud as a rock concert, since the sound waves produced have a tiny amplitude.
In both cases, how loud or soft the sound is perceived by our ears depends on the amplitude of the sound waves. Low-amplitude sounds are soft and quiet, but high-amplitude sounds are strong and loud.
Hence, rock concerts and whispers are examples of a high-amplitude sound and a low-amplitude sound.

Answer:
C) 4.0026 amu
Explanation:
Helium (He) is the 2nd element on the Periodic Table.
It's neutral atom has 2 protons and 2 electrons.
It is in the 1st period and the 18th row.
It is also a Noble gas.
The relationship between the stiffness of a medium and the speed of the wave is directly proportional. Because molecules are closer in a stiff medium, an increase of stiffness in a medium would also result to an increase in which a wave travels.
Answer:
the density of ordinary (baryonic) matter in the universe
Explanation:
Deuterium detection is of interest because the amount of it may be related to the amount of dark matter in the universe, but precise measurements have been difficult to obtain. Due to the way in which deuterium was created in the Big Bang, an exact measurement of the amount of deuterium would allow scientists to set limits on the models of the great explosion.
Also, an exact measure of deuterium would be an indicator of the cosmic density of barions (ordinary matter), and that density of barions would indicate whether ordinary matter is dark and is found in regions such as black holes, gas clouds or brown dwarfs, or it is bright and can be found in the stars. This information will help scientists who try to understand the very beginning of our universe.
