how loud a sound is
how high or low a sound is
the loudness or softness of a sound
A student placed an electric bell in a sealed jar and then removed the air from the jar using a vacuum. The expected result of this experiment would be:
silence because vibrations cannot be transmitted to the jar through a vacuum.
a lower pitched bell because sound absorbed by glass
an increase in amplitude because sound travels better in glass
an increase in amplitude because sound travels better in glass

pitch
frequency
Why is the school library covered with carpet?
To help absorb sounds to keep it quiet
To help absorb sounds so it can stay noisy
So everyone can make a lot of noise
because it looks good
What do bats and dolphins use to find things?
echolocation
their eyes
their ears
You will see a flash of lightning before you hear the thunder that goes with it because
light travels faster through the atmosphere than sound
thunder occurs much later than lightning
the eye is quicker than the ear
sound travels faster through the atmosphere than light
