B
True, you only need one trial.
C
True, people should give a lot of input right away.
D
False, you need to build two types to test.
7) How does sound travel?
A
Sound is a vibration that travels as a transverse and compression wave.
B
Sound is a vibration that travels as a compression wave.
C
Sound vibrates.
D
Sound is a vibration that travels as a transverse wave.
8) Sound waves transfer energy through a _____.
A
wall
B
air
C
medium
D
water
9) How does hitting a drum create a sound?
A
The drum skin vibrates; air particles move away; air particles travel to ear drums.
B
The drum skin vibrates; this compresses air particles; the air particles transfer as a compression wave through the air.
C
The drum skin asks to be hits again; then makes a noise that travels through the air.
D
The drum skin compresses; the compression affects air particles; air particles travel to your ears.
10) Sound travels fastest through
A
gases
B
solids
C
liquids
