3. The relation between the intensity I W/m and the intensity level D dB of a sound can be represented by the following formula: D=10log 10 12 (a) If the intensity of the sound in a bookstore is 10 W/m, find the intensity level (in dB) of the sound. (b) If the intensity level is halved now, find the intensity (in W/m 2 ) of the sound
