The loudness in decibels is
L = log₁₀(I/I₀)
where
I = sound intensity, W/m^2
I₀ = reference intensity, = 10^(-12) W/m^2
Raja's power level is 10^(-7) W, therefore the decibel value is
L = 10 log₁₀(10^(-7)/10^(-12))
= 10log₁₀10^5
= 10*5
= 50 dB
Answer: 50 dB
Answer:
$13.2
$113.20
Step-by-step explanation:
Simple interest for the fourth year = 13.20 ( 3.30 - 4)
New amount in the bank acount for 4th year = 100+ (3.30 x4) = 113.20
