A middle-A tuning fork vibrates with a frequency f of 440 hertz (cycles per second). You strike a middle-A tuning fork with a fo
rce that produces a maximum pressure of 5 pascals. Write a sine model that gives the pressure P as a function of the time t (in seconds).A middle-A tuning fork vibrates with a frequency f of 440 hertz (cycles per second).

We calculate current from the formula: , where q is a electric charge transferred over time t Time should be converted to seconds: 1h 15 min= 75min= 4500s I= Result is in unit-Ampere
