Find the number of decibels for the power of the sound given. Round to the nearest decibel. A rocket engine,2.44 cross 10^(−5)watts/cm2.

dB=10log(I/I0)

=10log(2.46∗10−1/10−12)

=10log(2.46∗1011)=113.91dB−−−−−−−−−ans

A rocket engine, 2.39 cross 10−5watts/cm2

To find the number of decibels for the power of the sound, you can use the formula:

L = 10 * log10(I / I0)

where L is the sound level in decibels, I is the power of the sound in watts per square centimeter (W/cm^2), and I0 is the reference power level, which is typically set at 10^(-12) W/cm^2.

Given that I = 2.44 * 10^(-5) W/cm^2, we can calculate the sound level as follows:

L = 10 * log10(2.44 * 10^(-5) / 10^(-12))

L = 10 * log10(2.44 * 10^7)

L = 10 * (log10(2.44) + log10(10^7))

L = 10 * (0.387 + 7)

L = 10 * 7.387

L ≈ 73.87 decibels

Rounding to the nearest decibel, the sound level is approximately 74 decibels.
