Final answer:
The difference between the intensities of the two sounds with intensities 2.3 x 10⁻⁶ W/m² and 6.5 x 10⁻⁶ W/m² is 4.2 x 10⁻⁶ watts per meter squared.
Step-by-step explanation:
The question asks about calculating the difference between the intensities of two sounds, with intensities given in watts per meter squared (W/m²). The difference between the intensities of the first sound (2.3 x 10⁻⁶ W/m²) and the second sound (6.5 x 10⁻⁶ W/m²) can be found by simply subtracting the intensity of the first sound from the intensity of the second sound:
Intensity difference = 6.5 x 10⁻⁶ W/m² - 2.3 x 10⁻⁶ W/m²
Intensity difference = 4.2 x 10⁻⁶ W/m²
Therefore, the difference between the intensities of the two sounds is 4.2 x 10⁻⁶ watts per meter squared.
