Find the number of decibels for the power of the sound given. Round to the nearest decibel.
A rocket engine,
2.42 * 10^5 watts cm^2
what is the db?
3 answers
db=10*Log(2.42*10^5)=10*Log(242000) = 54
Correction:
db = 10*Log(2.42*10^5/10^-16) =
10*Log(2.42*10^21) = 81
db = 10*Log(2.42*10^5/10^-16) =
10*Log(2.42*10^21) = 81
Oops!!
10*Log(2.42*10^21) = 214 db.
10*Log(2.42*10^21) = 214 db.
