Two students are standing the same distance from a source of sound. The first student receives a power of (36 × 10⁻6) W in their eardrum. The second student receives (1.28) times more power in their eardrum. If the second student's eardrum has a diameter of (d = 1) cm, what was the intensity of the sound that the student heard, in watts per square meter?
a. (36 × 10⁻6) W/m(²)
b. (46.08 × 10⁻6) W/m(²)
c. (64.8 × 10⁻6) W/m(²)
d. (0.46 × 10⁻6) W/m(²)
