A fan at a rock concert is 40.0 m from the stage, and at this point the sound intensity level is 114 dB . Sound is detected when a sound wave causes the tympanic membrane (the eardrum) to vibrate. Typically, the diameter of this membrane is about 8.40 mm in humans. E = 13.9  μJ   v = 3.73  m/s   Part C How fast would a typical 2.0 mg mosquito would have to fly (in mm/s) in order to have a kinetic energy...
