Sound 1 has an intensity of 47.0 w/m^2. sound 2 has an intensity level that is 2.6 db greater than the intensity level of sound 1. what is the intensity of sound 2? express your answer using two significant figures.

The intensity of Sound 2 up to two significant digits is  

Solution:

As per the question:

Intensity of Sound 1,

Intensity of Sound 2,

Now,

The intensity of sound in decibel (dB) is:

where

= threshold or critical sound intensity

Now,

Intensity of Sound 1, in dB is given by:

Therefore,

Now,

The Intensity, in is given by:

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
