A couple attends an outdoor symphony in July and again in December. During the second performance, they both notice a delay in the sound, which gives the impression that they are listening to a recording rather than a live performance. What principle of the speed of sound best explains their observations?
The speed of a sound wave varies with its wavelength and frequency.
The speed of a sound wave depends upon the temperature of its medium.
The speed of a sound wave is affected by the stat of matter of the medium.
The speed of a sound wave changes depending on the density of the particles in the medium.
What role does the inner ear play in hearing?
Captures sound waves
transmits sound waves from air to fluids
converts sound waves into electrical signals
removes high and low sound waves that are harmful
The vibrating string shown produces a sound. If the same string produced a louder sound, how would the string's appearance change?

The string would vibrate to a higher height.
The string would vibrate over a longer distance.
The string would vibrate over a shorter distance.
