A sub-contra-octave A tuning fork (corresponds to the lowest note on a piano keyboard) vibrates with a frequency f of 27.5 hertz (cycles per second). You strike a sub-contra-octave A tuning fork with a
force that produces a maximum pressure of 4 Pascals. Write and graph a sine model that gives the
pressure P as a function of the time t (in seconds).
