A sound source is at rest and has a frequency of 460Hz. An observer is moving towards the source at a speed of 34.9 m/s. Calculate the frequency heard by the observer. Use 338 m/s for the speed of sound in air.

The wavelength of a certain sound source is 2.4mm in air and the speed of sound in air is 345 m/s. What is the frequency of this sound source?

2. These two classes of sounds are in complementary distribution. In a sentence or two, clearly state how you can tell that they’re in complementary distribution. Be as specific as possible.

3. Using features, characterize the environments where the alternation between plain and aspirated stops occurs. (One of the environments will be “elsewhere”.)

• [p t k q] occur:

• [pʰ tʰ kʰ qʰ] occur:

4. Using features, character the natural segment classes consisting of       [p t k q] and of [pʰ tʰ kʰ qʰ].

• [p t k q]:

• [pʰ tʰ kʰ qʰ]:

5. Write a rule (in formal notation) that describes the relationship between [p t k q] and [pʰ tʰ kʰ qʰ] in Central Alaskan Yup’ik.

6. Show derivations for the following surface forms.

You do hot have a thermometer to measure temp you are able to measures the speed of sound through the air. If you measure the sound to be 349m/s. what is the air temp?
