Please answer both questions carefully
(a) Determine the intensity of sound in W/m2 reaching a person sitting at a distance of 5 m from a 200-W loud speaker. (b) The level of sound for threshold of hearing with intensity given by 1,-10x 10 given by 1,- 1.0x 10-12 W/m Wm is 0 decibel. Find the intensity of sound for a level of 50 decibels hi threshold of hearing.
