Abystander observes the musicians heading toward each other. when musician #1 is 100 m away, the intensity is 1.24 x 10-8 w/m^2. what is the intensity and intensity level when musician #1 is 25 m away?

Explanation:

Given that,

Distance 1, r = 100 m

Intensity,

If distance 2, r' = 25 m

We need to find the intensity and the intensity level at 25 meters. Intensity and a distance r is given by :

.........(1)

Let I' is the intensity at r'. So,

............(2)

From equation (1) and (2) :

Intensity level is given by :

,

dB = 32.96 dB

Hence, this is the required solution.

pe = weightxheight = 2000x1000=2,000,000joules

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
