Energy Absorbed by Ear from 95-dB Sound Wave

[helppppp]

A 95-dB sound wave strikes an eardrum whose area is 5.0 x 10¯5 m². How much energy is absorbed by the eardrum per second? ...been stuck on this question for so long.

First, convert decibels to "intensity" using that equation with the "log" in it. Intensity equals power divided by area, measured in "watts per meter squared."

Your answer, "energy per second" is the same thing as power.
