A fan at a rock concert is 35.0m from the stage, and at this point the sound intensity level is 108dB . Sound is detected when a sound wave causes the tympanic membrane (the eardrum) to vibrate . Typically, the diameter of this membrane is about 8.40mm in humans

1) How much energy is transferred to her eardrums each second ? the answer should be in microJoules.

2) How fast would a 2.00mg mosquito have to fly to have this much kinetic energy?

3) How fast a typical 2.0 mg mosquito would have to fly (in mm/s) to have an amount of energy delivered to the eardrum each second when someone whispers (20 dB) a secret in your ear?

4) Compare the mosquito's speeds found in parts (B) and (C).Please enter your answer as a number (factor) without the units.
