Sam is standing at the edge of a cliff. Zie rings a tuning fork that has a power of P at a distance of x, from zir ear. Sam then drops the tuning fork from rest and it falls over the edge of the cliff!! [15 points] a. Derive a formula for intensity of the sound zie hears after the tuning fork has been falling for a time T. You can ignore air resistance, the horizontal displacement of the tuning fork from zir ear (all distances are vertical), and can assume the power stays the same as the tuning fork falls. Your equation should only involve variables defined in the problem, numbers, and physical constants if needed. [ 6 points] b. Derive a formula for the change in decibel level of the tuning fork that Sam would hear after it had been falling for time T. Note: you are comparing the sound levels before it is dropped and after falling for time T. Your equation should only involve variables defined in the problem, numbers, and physical constants if needed [6 points] c. What is the change in the decibel level if the tuning fork started at 2.54 cm from zir ear and has been falling for 2.1 seconds? [ 3 points ] Sam is standing at the edge of a cliff.
