Solidification) Consider the 3-D sound wave created by a person playing a clarinet.

a)What is oscillating in the medium?

b)What is traveling through space and time that makes this a wave?

c)What determines the wave speed? What determines the amplitude? How could you change either of these quantities?

d)Explain the difference between the motions of air molecules due to the sound created by the clarinet to the motion of air molecules due to a gust of wind.

Please see the answer below

Explanation:

a)

The pressure of the air is oscillating in the medium when a person plays the clarinet.

b)

Energy is the physical property that is propagating through space.

c)

- Temperature and molecular mass (air) determines the speed of the waves.

- The amplitude depends of the energy generated by the person when he is playing the clarinet.

- The temperature can be changed by introducing heat in the air to increase the temperature, or with enough wind to slow down the temperature.

d)

- Motion of air molecules generated by the sound of clarinet consists in oscillating motions of molecules in a definite region, oscillation that are produced by the change in the air pressure. In this sense the molecules that we hear are different from the molecules that were vibrating near of the clarinet, these were transmitting to each other the energy of the propagation until the molecules that are near of us.

- In the case of the wind, air molecules do not oscillate in a definite region. Here, molecules are translated trough space.

hope this helps!!

the answer is b

explanation:

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
