Sound 1 has an intensity of 45.0 w/m2. sound 2 has an intensity level that is 3.2 db greater than the intensity level of sound 1. what is the intensity level of sound 2?

The intensity level of sound 2 is 93.3\ W/m².

Explanation:

Given that,

Intensity of sound 1 = 45.0 W/m²

Intensity level of sound 2 = 3.2 dB

We need to calculate the intensity

Using equation of the sound level intensity

The intensity of sound 2 is greater than 3.2 dB.

Therefore,

Calculate the intensity of sound 2

Hence, The intensity level of sound 2 is 93.3\ W/m².

option number c is the right answer.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
