<h2>Answer: The <u>height</u> of a sound wave determines its <u>loudness</u> </h2>
Sound waves are longitudinal mechanical waves, that is, they depend on a medium to propagate.
Among the characteristics of a sound wave, it is the amplitude, that is the degree of movement of the molecules of the medium in which the wave propagates.
Depending on how high this amplitude is, the sound will be louder.
Answer:compound is a poly element pure substance
Explanation:
It made up of two or more elements.
It can be broen down into simpler units
The decrease in gravitational potential energy of the system is given by
where
m is the mass, g is the gravitational acceleration, and 
is the variation of height of the system.
also corresponds to the weight of the diver, therefore if we rearrange the equation and we use 
and 
, we can find her weight:
