Answer:
<u>Frequency</u>- number of wave cycles that occur in a given amount of time.
<u>Pitch</u>- number of wavelengths in a given amount of time.
<u>Amplitude</u>- fluctuation or displacement of a wave from its mean value. That means how high or low they are away from the center line.
<u>Volume</u>- The perception of loudness from the intensity of a sound wave. The higher the intensity of a sound, the louder it is perceived in our ears, and the higher volume it has.
<u>Wavelength</u>- the distance between the tops of the "waves".

Answer:
In an earthquake prone area, the things that are needed to be considered for the buildings to stand constant and no cause of damages are as follows-
- The foundation of the building must be made strong, using large amount of concretes so that it can hold the entire load of the building.
- The pillars of the buildings are also should be firmed, rigid, strong and thick.
- The buildings are needed to be construct in such a way that during any seismic event, the forces can be redistributed easily through the body of the building without causing any damage.
- The buildings must be overall comprised of holding high strength and stiffness.
The answer is B. I hope this helps! :)
