    1. The problem statement, all variables and given/known data
    1. "When filling your car with gasoline, in the last few seconds before filling the tank, a noise with a rising pitch comes from the tank. Explain"
    2. "Liona Boyd, a famous Canadian guitarist, tunes her guitar's A string with a 440 Hz tuning fork. Beats are heard at a frequency of 4 Hz. To give herself more information, Mrs. Boyd wraps a piece of masking tape around one of the tuning fork tines and continues tuning. This time, a beat frequency of 5 Hz is heard. Is more information required to find the specific frequency of the string? What are the possible frequencies of the string? In each case, what should Ms. Boyd do to tune the string?"
