Question

A jet plane emits 3.0*10^5 J of sound energy per second.

a)What is the sound level 21m away

I have attached pictures of Partb and Partc 

Air absorbs sound at a rate of about 7.0 dB/km; calculate what the sound level will be 4.00 km. Express your answer using two significant figures. B = ΑΣΦ I ? dB
