An audience member experiences sound of intensity I as an orchestra member plays a flute.  If the audience member moves farther back so that the distance from the flute player is doubled, then I would:A.decrease by a factor of 4.B.decrease by a factor of 2.C.remain the same.D.increase by a factor of 2.

Doubling the distance between sound source and a listener will change the intensity, as detected by the listener, by what factor?Select one:a.2b.1/4c.4d.1/2

Question 59A musician plays the trumpet in a marching band.  The musician tunes the trumpet inside a room and then goes outside to play.  When outside, the trumpet sounds flat (plays a lower frequency).  Which of the following has occurred to account for the decrease in the frequency?A.The air outside is warmer than inside, which increased the speed of the sound waves.B.More energy is dissipated outside, which caused the sound waves to lose energy.C.The musician shortened the length of the trumpet, which decreased the wavelength of the sound waves.D.The air outside is cooler than inside, which decreased the speed of the sound waves.

: Which of the following is proportional to the amplitude of the sound where the frequency remainsconstant?

Light intensity decreases as the distance between the light source and the plant increases. This is called __________ proportionality. What word completes the sentence?

If air in the room is warmed up, the speed of sound in it(1) increases(2) decreases(3) remains the same(4) fluctuates
