Answer 1

The new intensity of the sound wave is 60 W/cm²

Step-by-step explanation:

The intensity of a sound wave is a measure of the power carried by the wave per unit area. It is given by the formula I = P/A, where I is the intensity, P is the power, and A is the area.

If the initial intensity is 6 W/cm² and it is raised by 10 decibels, we can use the formula:

I2 = I1 * 10^(dB/10)

Substituting the given values, we have: I2 = 6 * 10^(10/10) = 60 W/cm².
