Aperson wears a hearing aid that uniformly increases the sound level of all audible frequencies of sound by 28.1 db. the hearing aid picks up sound having a frequency of 250 hz at an intensity of 3.30 10-11 w/m2. what is the intensity delivered to the eardrum?

This is what i found on google “what happens to the bond angle when you add or remove an electron domain? the bond angle decreases as you add domains 5. can you force the atoms into new configurations by pushing atoms around? note: we can think of a bond or a lone pair of electrons as a “domain” of electrons.” i hope this you

Wish i knew this to !
