if the intensity of a mosquito's buzzing is 9.3 x 10^-8 W/m^2 at a distance of 0.21 m, how much sound power does that mosquito generate?

The sound power generated by the mosquito can be calculated using the equation W = I * (4πr^2), where I is the intensity of the sound and r is the distance from the source of the sound. In this case, the intensity is 9.3 x 10^-8 W/m^2 and the distance is 0.21 m. Substituting these values into the equation we get W = 9.3 x 10^-8 W/m^2 * (4π(0.21 m)^2) = 1.381 x 10^-8 W. This means the mosquito is generating 1.381 x 10^-8 W of sound power.
